0:02 imagine a line a simple unbroken line
0:05 stretching into
0:07 Infinity this line in its purest form
0:10 represents the First Dimension a realm
0:13 of length but without depth a universe
0:16 infinitely long but impossibly
0:19 thin now let's broaden our perspective
0:23 introduce a second line intersecting the
0:25 first and suddenly we're in the realm of
0:27 the second dimension a plain where
0:30 length and width interact in harmony but
0:33 depth remains a variable alien to
0:36 them as we go one step higher we find
0:39 ourselves in the familiar Embrace of the
0:41 third dimension this is where depth
0:43 comes in adding volume and substance to
0:46 our world buildings rise valleys deepen
0:50 and the universe takes on texture and
0:53 shape but what if we get out another
0:56 layer time is The elusive fourth
0:58 dimension that permeates our
1:00 three-dimensional space invisible but
1:04 omnipresent it dictates the rhythm of
1:06 Our Lives a continuous thread connecting
1:09 each previous moment with the current
1:10 one and the current one with the
1:13 next in this realm our understanding of
1:16 reality becomes more complex and broader
1:19 here the very fabric of the universe
1:21 reveals its complexity hinting at
1:23 Dimensions beyond our sensory
1:26 perception however nature hints at even
1:29 more complex
1:31 dimensions in the field of physics theor
1:34 suggests the existence of Dimensions
1:36 beyond our perception necessary for the
1:38 fundamental forces that govern the
1:41 universe these higher Dimensions
1:43 although beyond our sensory perception
1:45 are crucial to understanding the
1:47 structure of the
1:48 cosmos join us as we try to unravel
1:51 their Mysteries together today one
1:54 dimension at a time

2:06 in a historical context the concept of
2:09 measurement permeates all human thought
2:11 from the abstract reflections of ancient
2:13 philosophers to the Revolutionary
2:16 discoveries of modern
2:17 physics philosophers once pondered the
2:20 nature of existence laying the
2:22 foundations for our understanding of
2:24 space in their discussions they
2:26 questioned the very essence of reality
2:29 imagining Realms beyond the tangible as
2:32 the centuries passed these philosophical
2:35 speculations paved the way for more
2:37 structured inquiry into the nature of
2:39 the
2:39 universe meet the Visionary Herman
2:42 manowski who irrevocably changed our
2:45 understanding by proposing that time and
2:47 space are not separate entities but
2:50 intertwin Dimensions that form the
2:52 fabric of
2:53 SpaceTime Albert Einstein in turn based
2:56 on the foundation laid by manowski
2:59 presented the evolutionary theory of
3:01 general relativity restructuring our
3:04 understanding of gravity space and time
3:06 in a single Continuum forever changing
3:09 the course of
3:10 physics thus from the philosophical
3:13 quest of the ancient thinkers to the
3:15 scientific revolutions sparked by
3:17 manowski and Einstein the journey
3:19 through the evolution of spatial
3:21 thinking reveals a Relentless quest to
3:23 comprehend the true nature of our
3:25 universe
3:30 so over time we've come to realize that
3:33 to truly comprehend the fabric of our
3:35 reality we must go beyond the three
3:37 tangible Dimensions into the realm of
3:40 the fourth dimension
3:44 time the concept of time as a dimension
3:47 is both profound and persuasive to our
3:50 existence and the universe as a whole
3:53 unlike the three spatial Dimensions time
3:56 has a direction it moves inexorably
3:58 forward from the path past through the
4:00 present and into the
4:03 future this unidirectional flow of time
4:06 distinguishes it from space bringing to
4:09 the universe a temporal structure that
4:11 is fundamental to our understanding of
4:14 reality to illustrate the importance of
4:17 time as a dimension consider a simple
4:19 everyday scenario organizing a meeting
4:22 when we suggest that someone meet at a
4:24 certain place we unconsciously navigate
4:27 the three basic spatial Dimensions to
4:29 determine
4:30 where it makes sense that if we arrived
4:33 at different places no meeting would
4:35 take
4:36 place however the when the dimension
4:39 without which the meeting will not take
4:41 place is no less important that is
4:44 coming with your friend to the same
4:46 place but at different time intervals
4:48 you'll not be able to see each other
4:51 this intertwining of space and time is
4:54 manifested in the concept of world line
4:57 the path that an object or person person
5:00 takes through SpaceTime thus
5:02 representing its history and
5:04 future the idea of world lines provides
5:08 a vivid illustration of how events are
5:10 linked together in the fabric of
5:12 SpaceTime for two people to meet their
5:14 world lines must intersect at a precise
5:17 point in both space and time this
5:21 intersection is not just a coordinate
5:23 but a space-time coordinate the only
5:26 point in the vast Continuum of the
5:28 universe where both both where and when
5:32 coincide this principle applies not only
5:35 to simple encounters but also to the
5:37 fundamental workings of a
5:39 cosmos celestial bodies from planets to
5:42 Stars Trace their own world lines
5:44 through SpaceTime their paths determined
5:47 by the interplay of spatial positions
5:50 and temporal
5:51 moments for example the Earth's orbit
5:54 around the sun is not just a path
5:55 through space but a continuous Journey
5:58 Through Time with each point in the
6:00 orbit representing a unique moment the
6:03 integration of time as a dimension has a
6:06 profound effect on our perception of the
6:09 universe it forces us to look Beyond
6:11 static images of space to the dynamic
6:14 unfolding of
6:16 events time allows us to understand the
6:19 universe not as a set of individual
6:21 moments but as a continuous narrative
6:25 where cause and effect bind our reality
6:28 into a coherent
6:30 Hall the inclusion of time as a
6:33 dimension has catalyzed major advances
6:35 in physics particularly through
6:37 Einstein's theories of Relativity which
6:40 we've already
6:41 mentioned these theories not only
6:43 deepened our understanding of the cosmos
6:45 but also pav the way for new research in
6:47 quantum mechanics and
6:50 cosmology Einstein's Revelation that
6:53 time is relative it slows down or
6:55 shrinks depending on the velocity of an
6:57 object challenge the idea of a universal
7:00 clock this concept rooted in the special
7:04 theory of relativity illustrates how the
7:06 passage of time changes for observers in
7:09 different reference
7:11 frames this phenomenon is confirmed by
7:14 experiments for example with atomic
7:16 clocks on fast moving
7:19 airplanes in quantum mechanics time as a
7:23 dimension underlies the evolution of
7:25 particle state governed by the
7:26 Schrodinger equation
7:29 this basis is important for
7:31 understanding phenomena such as
7:32 entanglement and superposition where the
7:35 time Dimension provides a probability
7:37 distribution of
7:42 outcomes going beyond the fourth
7:45 dimension opens the door to a realm
7:47 where our everyday experience and the
7:49 laws of physics as we know them are
7:52 fundamentally challenged and
7:55 expanded in search of a unified theory
7:57 that harmonizes the principles of
7:59 quantum mechanics and the general theory
8:01 of relativity physicists have ventured
8:04 into the theoretical landscape of higher
8:07 Dimensions where the fabric of the
8:09 universe becomes even more intricate and
8:14 mysterious The Fifth Dimension and
8:16 Beyond are not just speculative
8:18 constructs but important components in
8:21 the Quest for a deeper understanding of
8:22 the
8:23 universe in theory such as String Theory
8:27 these higher Dimensions offer solutions
8:29 to physics most challenging Mysteries
8:31 including the unification of fundamental
8:33 forces and the nature of gravity at
8:35 Quantum
8:37 scales the difficulty in visualizing
8:40 higher Dimensions is that our perception
8:43 is inherently three-dimensional
8:45 therefore analogies become an invaluable
8:48 tool one of the classic analogies to
8:50 help understand the concept of higher
8:52 Dimensions is to imagine the perspective
8:55 of a two-dimensional being often called
8:58 a flatlander living living in a flat
9:00 two-dimensional world this being can
9:03 move forward and backward left and right
9:06 but has no concept of moving up and down
9:09 because these Dimensions do not exist in
9:11 its two-dimensional
9:14 experience imagine a three-dimensional
9:16 sphere passing through this
9:17 two-dimensional
9:19 world to a flat Lander the sphere would
9:22 first appear as a DOT when the sphere is
9:25 just touching the two-dimensional plane
9:27 gradually increasing into a circle as
9:30 more of the sphere passes through the
9:32 plane and then decreasing again to a
9:35 point as the sphere leaves the plane
9:38 before disappearing
9:40 altogether a two-dimensional being would
9:43 perceive this event as a circle that
9:44 appears out of nowhere changes size and
9:48 then
9:49 disappears without realizing what
9:51 three-dimensional object is causing the
9:55 phenomenon String Theory the leading
9:58 candidate for a unified Theory posits
10:01 that particles are not the individual
10:03 points we see them to be but tiny
10:05 vibrating strings whose modes of
10:08 vibration determine the properties of
10:09 the
10:10 particles this Theory requires the
10:13 existence of more than four known
10:14 dimensions in fact it suggests that
10:17 there may be as many as 10 or 11 these
10:20 additional dimensions are compacted or
10:23 convolved so that they are imperceptible
10:26 on our scale like the sphere in the
10:29 flatlander
10:32 example in The Fifth Dimension we
10:34 encounter a space containing all
10:36 possible universes that start from the
10:39 same initial conditions as our own
10:42 Universe imagine a tree each branch
10:46 representing a different decision or
10:48 outcome leading to a different reality
10:50 all coming from the same
10:52 trunk just as a person standing at the
10:55 base of the tree can choose which branch
10:57 to climb a being with access to The
11:00 Fifth Dimension can explore these
11:02 alternate realities each A variation of
11:05 our own universe but with slightly
11:07 different
11:11 outcomes the ascent to the sixth
11:13 Dimension opens a plane containing all
11:15 possible universes with the same initial
11:18 conditions as ours but with any possible
11:20 set of laws of
11:22 physics if we think of each universe as
11:25 a sheet of paper the sixth Dimension
11:27 would be like a stack of s sheets each
11:30 representing a different
11:32 Universe a being capable of traveling
11:35 through the sixth Dimension could hop
11:37 between these universes learning the
11:39 different outcomes and laws governing
11:41 each
11:44 reality the seventh Dimension extends
11:47 this concept to include universes that
11:49 start from different initial conditions
11:52 to use a library analogy each book
11:55 represents a different Universe the
11:57 seventh Dimension encompasses the entire
12:01 Library offering not just different
12:03 stories universes with the same initial
12:06 conditions as ours but with different
12:07 outcomes but completely different genres
12:11 universes with different initial
12:13 conditions a 7-dimensional being could
12:16 move through this Library experiencing
12:19 an infinite number of universes each
12:22 with its own unique initial conditions
12:24 and physical
12:27 laws in the eighth Dimension we find a
12:30 web of all possible
12:33 universes each with its own initial
12:36 conditions and laws of physics as well
12:38 as all possible variants of their
12:40 development in
12:42 Time Imagine a huge web where each
12:46 thread represents the timeline of a
12:48 separate universe and each node where
12:51 the threads cross represents an
12:53 important event that could lead to the
12:55 branching of new
12:57 universes the eighth dimension
12:59 encompasses this entire web allowing you
13:02 to travel between any nodes exploring
13:04 the connections between different
13:06 universes and their
13:10 history as we approach the ninth
13:12 Dimension we encounter all possible laws
13:15 of physics and initial conditions that
13:17 have existed or will ever
13:20 exist this Dimension can be compared to
13:22 the art of origami where a single piece
13:25 of paper can be folded into numerous
13:27 shapes each fold represents a change in
13:30 the initial conditions or laws of the
13:33 universe and the ninth Dimension
13:35 includes all possible combinations of
13:37 folds resulting in all conceivable and
13:40 inconceivable
13:42 universes a being living in the ninth
13:44 Dimension will not just have absolute
13:47 freedom to cross the boundaries between
13:49 all possible Realms of reality it will
13:51 experience all existence and all its
13:54 possible variations
14:00 the 10th Dimension is the Pinnacle of
14:02 the hierarchy of Dimensions where all
14:05 possible outcomes realities and
14:07 existences
14:09 converge it's the space that encompasses
14:12 all conceivable and inconceivable
14:14 timelines for every conceivable Universe
14:17 effectively encompassing all
14:19 possibilities of existence and
14:23 non-existence this concept can be
14:25 visualized as an infinitely complex
14:28 branching tree or network where each
14:31 branch represents a different outcome or
14:34 timeline and all branches ultimately
14:36 converge at one point the 10th
14:40 Dimension visualizing the 10th Dimension
14:42 is challenging because of its abstract
14:45 nature one approach is to use the
14:48 analogy of a tree where each branch
14:51 represents a different timeline or
14:54 universe and each Leaf represents a
14:56 possible outcome within that universe
15:00 moving from trunk to leaves we move from
15:02 the initial conditions of the universe
15:04 lower Dimensions through the various
15:07 choices and events higher Dimensions
15:10 that lead to all possible
15:13 outcomes the 10th Dimension represents
15:15 the point where all these possibilities
15:18 Come Together The Singularity of
15:20 infinite potential
15:23 outcomes it suggests a cosmos in which
15:26 all possible outcomes not only can
15:28 happen but happen in some timeline or
15:31 Universe in the 10th
15:33 Dimension the concept itself invites us
15:36 to reflect on the vastness of
15:38 possibilities that lie beyond our
15:40 observable
15:41 universe it raises questions about fate
15:45 choice and the underlying structure of
15:47 the
15:48 cosmos prompting a broader exploration
15:51 of potential realities that may exist
15:54 beyond our immediate perception
16:00 the exploration of higher Dimensions
16:02 beyond our familiar three-dimensional
16:04 space and fourth-dimensional time has
16:08 profound implications for both physics
16:10 and
16:11 cosmology not only is this field of
16:14 study designed to challenge our
16:15 fundamental understanding of the
16:17 universe but it may also hold the key to
16:20 uniting the disparate forces of nature
16:23 potentially solving some of cosmology's
16:25 most enigmatic
16:27 puzzles recogniz izing the existence of
16:30 higher Dimensions plays a key role in
16:32 the search for a Theory of Everything a
16:34 single framework that will seamlessly
16:37 UniFi general relativity in quantum
16:40 mechanics currently these two pillars of
16:43 modern physics describe the Cosmos on
16:45 very different scales and in seemingly
16:47 incompatible terms general relativity
16:50 perfectly explains the gravitational
16:53 interaction of massive celestial bodies
16:56 while quantum mechanics reveals the
16:58 inter world of subatomic
17:01 particles higher Dimensions may also
17:04 offer new insights into cosmological
17:06 Mysteries such as dark matter dark
17:09 energy and the nature of black
17:12 holes for example some theor suggest
17:15 that what we perceive as dark matter may
17:17 be gravitational effects from matter in
17:19 parallel
17:21 branches a concept from M Theory which
17:24 suggests multiple parallel membranes or
17:27 brains as fundamental components of the
17:31 universe each potentially containing
17:33 Another Universe in higher
17:36 Dimensions looking to the Future in the
17:39 field of energy mastering the
17:40 intricacies of higher Dimensions could
17:42 pave the way to harness forms and
17:44 mechanisms of energy that we cannot now
17:47 even imagine and potentially lead to the
17:50 creation of clean virtually in
17:52 exhaustible sources of
17:54 energy similarly the field of space
17:57 travel could be revolutionized by a
18:00 better understanding of the fabric of
18:01 SpaceTime perhaps eventually enabling
18:04 warp drives or other forms of faster
18:06 than light travel Concepts that are
18:09 currently in the realm of Science
18:10 Fiction but could be theoretically
18:13 plausible within higher
18:16 Dimensions the search for higher
18:18 Dimensions is already underway
18:20 researchers are exploring the subatomic
18:22 world with particle gas pedals such as
18:25 the Large Hadron Collider at CERN
18:27 looking for evidence of a additional
18:29 dimensions and the particles that may
18:31 inhabit them this experimental work is
18:34 complemented by theoretical studies that
18:36 delve physicists and mathematicians into
18:39 the abstract Realms of high dimensional
18:46 spaces as we complete our journey
18:48 through the dimensions from the
18:50 Simplicity of a line extending into
18:53 Infinity to the unfathomable complexity
18:56 of the 10th Dimension where faced with
18:59 the inherent challenge of visualizing
19:01 spaces beyond our three-dimensional
19:04 experience Through Math we can describe
19:06 properties and relationships within
19:08 higher dimensions and physics offers
19:11 theories such as string theory and M
19:14 Theory that hint of the existence of
19:16 these additional
19:18 Dimensions animation such as tasax
19:21 allows us to conceptualize High
19:23 dimensional shapes and their projections
19:25 or shadows in lower
19:27 dimensions further exploration of higher
19:30 Dimensions promises to revolutionize our
19:33 understanding of the
19:34 universe just as the transition from a
19:37 flat Earth to a spherical Earth many
19:40 centuries ago broadened Humanity's
19:44 Horizons this expanded perception has
19:46 the potential to influence not only
19:48 science but also art philosophy and all
19:52 aspects of human
19:53 creativity inviting us to rethink the
19:56 cosmos and our place in it
20:06 the moon has always been a beacon of
20:08 mystery and wonder but beyond its
20:10 radiant Beauty and folkloric tales the
20:13 moon holds secrets that have eluded us
20:16 for
20:16 centuries among these mysterious
20:19 features is the Moon South Pole a region
20:22 shrouded in Perpetual Shadow and intense
20:25 cold untouched and unexplored by any
20:28 previous lunar Mission this is the story
20:31 of chandrian 3 India's daring journey
20:34 into Uncharted
20:35 Territory launched on a journey of more
20:38 than
20:39 238,000 Mi chandrian 3 embarked on a
20:43 mission not just of distance but of
20:45 Discovery its purpose to unravel the
20:48 mysteries of the Moon South Pole a place
20:51 where sunlight barely reaches an area
20:53 where the terrain is so treacherous that
20:55 you have to through an endless Maze of
20:57 craters and
20:59 rocks here in this alien landscape
21:02 chandren 3 sought answers to questions
21:05 that have puzzled scientists for decades
21:07 What Lies Beneath the surface of this
21:10 mysterious region do earthquake like
21:13 Tremors shake the silent world and the
21:16 most exciting question is whether water
21:18 the elixir of Life exists here in the
21:21 form of
21:24 ice when chandran 3 ventured beyond
21:27 Earth it carried with it the aspirations
21:29 of a nation and the Curiosity of the
21:31 world its primary goal was clear yet
21:35 challenging to achieve a soft landing
21:37 near the moon's South Pole a feat that
21:39 had never before been accomplished from
21:42 The Busy mission control center of the
21:44 Indian space research organization a
21:47 team of dedicated scientists and
21:48 Engineers piloted this ambitious
21:51 Mission their expertise helped chandren
21:54 3 Traverse the space void overcoming the
21:57 challenges of lunar orbit insertion and
22:00 descent the South Pole of the moon is a
22:02 landscape unlike any other here the
22:05 terrain is a patchwork of craters and
22:07 mountains many of which are shrouded in
22:10 Perpetual Darkness the challenge was not
22:12 just to land but to land safely in an
22:15 area where the terrain is unforgiving
22:17 and most slopes are quite steep when the
22:20 vicrum landing modules separated from
22:22 the Orbiter it began its descent The
22:25 Landing module equipped with Advanced
22:27 sensors and engin
22:29 began its perilous Journey to the
22:31 surface of the Moon imagine a spaceship
22:33 autonomously navigating a maze of
22:35 craters and boulders in search of a
22:37 patch of land safe enough to land on the
22:40 landing modules onboard systems were
22:42 hard at work analyzing every inch of the
22:44 terrain below against this treacherous
22:47 landscape The Landing module also
22:49 struggled with extreme temperatures the
22:52 Moon South Pole is a place of Stark
22:54 contrasts the sun barely rises above the
22:57 Horizon on Shadows hide frigid
23:00 temperatures that can drop to - 382 de f
23:04 as the landing module made its Final
23:06 Approach the hearts of the flight
23:07 control center beat harder every second
23:10 was decisive every maneuver a test of
23:13 human Ingenuity and technological
23:15 prowess with light thud vicam landed
23:20 Land
23:22 mod marking and historic moment not only
23:25 for India but for lunar exploration in
23:27 general in the Silence of the Moon South
23:30 Pole chandrian 3 began its mission of
23:33 exploration and
23:36 Discovery so after the historic Landing
23:39 of chandren 3 a new chapter in lunar
23:41 exploration began the mission's goal was
23:44 to maximize the study of the moon's
23:46 characteristics especially its elusive
23:48 exosphere and ionosphere and to
23:52 establish the range of temperature
23:53 variations just beneath its surface the
23:56 lunar exosphere the thin layer of gases
23:59 surrounding the moon holds the key to
24:01 the satellites past and present unlike
24:04 Earth's robust atmosphere the moon's
24:06 exosphere is so rarified that it almost
24:09 resembles a vacuum the chander 3
24:12 instruments developed using the latest
24:14 technology are designed to measure the
24:16 density and composition of this elusive
24:18 layer in addition to the exosphere the
24:21 mission delve deeper into the moon's
24:23 ionosphere this layer formed by solar
24:26 energy ionizing atoms in the aop spere
24:28 plays a crucial role concerning lunar
24:31 communication and navigation the
24:33 chandrian 3 measurements were designed
24:35 to provide unprecedented information on
24:37 the density and behavior of the
24:39 ionosphere which is important for future
24:41 lunar missions and potential human
24:44 habitats another intriguing aspect of
24:47 the mission was studying the temperature
24:49 variations just beneath the lunar
24:51 surface using one of four instruments on
24:53 the landing module chased or chandra's
24:56 Surface thermophysical experiment
24:59 the temperature probe immersed in the
25:01 lunar regolith was tasked with a
25:03 critical mission of mapping the thermal
25:05 profile of the lunar soil the results of
25:07 chandrian 3 revealed a sharp contrast in
25:10 temperatures on the surface during a
25:12 lunar day temperatures Rose dramatically
25:15 to 140° F while just 8 cm deeper they
25:20 dropped significantly to 14° F
25:24 demonstrating the lunar soil as a
25:26 potential thermal insulator
25:29 this discovery provided new
25:30 opportunities for future lunar habitats
25:33 suggesting that the lunar regolith could
25:35 serve as a thermal insulator protecting
25:37 astronauts from the moon's harsh extreme
25:39 temperatures and harmful
25:41 radiation these studies were more than
25:44 just scientific Endeavors they were
25:46 Stepping Stones toward a future in which
25:48 the moon could be a gateway to Future
25:50 space exploration Mission results on the
25:53 lunar exosphere ionosphere and
25:55 subsurface temperature laid the
25:57 foundation for understanding the moon's
25:59 environment and its potential to support
26:02 human
26:04 life standing in the vast lunar
26:07 landscape chandrian 3 was ready to
26:09 detect a phenomenon that had not been
26:11 observed for more than 50 years a lunar
26:15 earthquake the mission succeeded in
26:17 shedding light on one of the most
26:18 intriguing and least understood aspects
26:20 of the Moon the instrument for lunar
26:23 seismic activity or ilsa a seismic
26:26 instrument was designed to detect the
26:28 slightest Tremors on the moon and it did
26:32 chandrian 3 detected what looked like a
26:34 lunar earthquake a significant Discovery
26:37 given that the last such observation was
26:39 made during the Apollo missions in the
26:41 early
26:42 1970s lunar Quakes are fundamentally
26:46 different from earthquakes while Earth's
26:49 seismic activity is largely due to the
26:51 movement of tectonic plates the moon
26:53 which is devoid of these plates
26:55 experiences earthquakes for a variety of
26:57 reasons
26:59 these Tremors can last much longer than
27:01 earthquakes sometimes up to an hour and
27:03 their origin is a subject of scientific
27:05 interest the chandrian 3 data suggest
27:08 several possible causes for these
27:10 earthquakes one theory is a collision
27:12 with meteoroids which could cause shock
27:15 waves that penetrate the moon's crust
27:17 another is Earth's gravitational pull
27:20 causing tidal forces that load the lunar
27:24 crust finally extreme temperature
27:26 fluctuations on the moon surface can
27:28 cause expansion and contraction leading
27:30 to earthquakes these earthquakes are not
27:33 just surface phenomena they're Windows
27:35 into the moon's interior by analyzing
27:38 the seismic waves scientists can infer
27:40 the composition and structure of our
27:42 satellites interior which resembles a
27:45 sonogram of the lunar interior such
27:48 information is of great importance for
27:50 understanding the formation and
27:52 evolution of the
27:53 Moon the detection of a lunar earthquake
27:57 of the chandren 3 spacecraft has not
27:59 only provided a glimpse into the dynamic
28:01 nature of our Celestial neighbor but has
28:03 also opened up new insights into the
28:06 geological processes that shape the
28:10 moon to unravel the geologic Mysteries
28:13 of the Moon chandran 3 carried out
28:16 another exploration among the most
28:18 intriguing finds was the discovery of
28:21 sulfur an element whose presence on the
28:23 moon has been shrouded in mystery the
28:26 laser induced breakdown spectroscope or
28:29 Libs Rover a Marvel of scientific
28:32 instrumentation vaporizes tiny samples
28:35 of lunar soil using high energy laser
28:37 pulses when the plasma emits light the
28:40 spectroscope analyzes its wavelength
28:43 thereby revealing the presence of
28:45 various elements including sulfur sulfur
28:48 on the moon is a significant find on
28:50 Earth sulfur is often associated with
28:53 volcanic activity raising questions
28:55 about similar processes on the moon in
28:57 the past its presence could provide
28:59 insight into the volcanic history of the
29:01 moon and the processes that shaped its
29:04 surface in addition to sulfur another
29:07 key objective of chandran 3 was the
29:09 search for water ice a search that's
29:12 intrigued scientists for decades water
29:15 ice on the moon is not just a scientific
29:17 curiosity it's a potential resource for
29:19 future human missions offering water for
29:22 life support and fuel
29:24 production despite High Hopes chandrian
29:27 3
29:28 like its predecessors found no direct
29:31 evidence of water ice on the moon's
29:32 surface however the lack of direct
29:35 evidence is not a conclusion but a clue
29:37 leading to new
29:41 hypotheses one theory is coal trapping
29:44 in which water vapor can migrate to
29:46 permanently shadowed Craters of the
29:48 poles freezing into ice the detection of
29:51 sulfur adds another layer to this Theory
29:53 as sulfur may be trapped with the water
29:55 ice and released as a result of the
29:57 breakdown of water molecules by high
29:59 energy solar
30:01 radiation the lack of direct evidence
30:03 for the existence of water ice raises
30:06 important questions is the ice deeper
30:08 beneath the surface shielded from
30:10 detection by the insulating properties
30:12 of the lunar soil or is its prevalence
30:15 more heterogeneous and Elusive than
30:17 previously thought during its
30:19 exploration of the Moon South Pole
30:22 chandrian 3 found more than just sulfur
30:24 the Rover's Libs instrument made the
30:26 first ever insitu do measurements of the
30:29 elemental composition of the lunar
30:30 surface in this
30:32 region in addition to sulfur the
30:34 instrument detected aluminum calcium
30:37 iron chromium and titanium each element
30:41 reflecting part of the complex geologic
30:44 history of the lunar surface further
30:46 measurements added new details to this
30:49 discovery further revealing the presence
30:51 of Manganese silicon and oxygen these
30:55 elements each with its own unique
30:57 spectral signature provided Clues to the
31:00 formation of the Moon and its
31:01 evolutionary history studies of the
31:04 presence of hydrogen a key component in
31:06 the search for water also continue the
31:09 mission's discovery of these elements
31:11 and the ongoing search for water ice
31:14 underscore the dynamic and complex
31:16 nature of the moon's geology each
31:19 Discovery each unanswered question moves
31:22 us further in our quest to understand
31:24 our nearest Celestial neighbor and
31:26 prepares us for the next steps in lunar
31:31 exploration as the chandrian 3 mission
31:34 at the Moon South Pole opened a new
31:36 chapter in lunar exploration it also
31:38 paved the way for the next ambitious
31:40 leap the lunar polar exploration mission
31:44 lupex for short this joint venture
31:47 between the Indian space research
31:49 organization and Japan Aerospace
31:51 Exploration Agency is scheduled to
31:53 launch no earlier than
31:55 2026 lupex plans to send an unmanned
31:58 lunar lander and Rover to further
32:00 explore the South Pole region of the
32:02 Moon Jaa will likely provide the H3
32:05 launch vehicle and Rover under
32:07 development and ISRO will provide the
32:09 Lander this Mission represents a
32:12 significant stepen International
32:13 cooperation on lunar
32:15 exploration the mission's goals are
32:18 multifaceted it will demonstrate new
32:20 Surface exploration Technologies
32:22 critical for sustained lunar exploration
32:24 in the polar regions precise Landings
32:27 will be achieved by using a feature
32:29 matching algorithm and navigation
32:31 equipment derived from the jaxa smart
32:34 Lander for investigating moon mission
32:36 the lupex Rover will carry several
32:39 instruments from jaxa and ISRO including
32:41 a drill capable of collecting samples
32:44 from a depth of 5 ft 1.5
32:47 M finding and analyzing water are key
32:50 goals of the mission and the potential
32:52 discovery of water ice could be a
32:54 GameChanger for future lunar
32:56 missions in parallel with lupex ISRO
33:00 chandry and 4 Mission designed to return
33:02 samples from the Moon is in the planning
33:04 stage scheduled for launch by 2028
33:08 chandrian 4 will consist of four modules
33:11 a transition module a descent module an
33:14 Ascent module and a re-entry module the
33:18 ambitious goal of the planned mission is
33:19 to return soil samples from the Moon
33:22 which will provide invaluable
33:23 information about the lunar
33:25 environment the mission will involve
33:27 complex Maneuvers including sample
33:29 collection docking in lunar orbit and
33:32 returning samples to
33:35 Earth chandrian 3's Innovative
33:38 discoveries from the detection of sulfur
33:41 and other elements to the study of lunar
33:43 earthquakes have revealed new layers of
33:46 the moon's mysterious nature these
33:49 results provide crucial insight into the
33:51 moon's geology its internal structure
33:54 and the potential for future lunar
33:56 habitats
33:58 looking ahead the future of lunar
34:00 exploration is promising missions like
34:03 lupex and chandrian 4 building on the
34:06 legacy of the previous ones will
34:08 continue to explore the mysteries of the
34:10 Moon India's role in these Endeavors is
34:13 not only that of a participant but also
34:15 that of a Pioneer such events truly
34:18 Inspire us to look beyond the boundless
34:21 Mysteries of the cosmos
34:30 the solar system has served as a
34:31 reliable buw workk for life but one day
34:35 Humanity will have to leave its native
34:37 Earth to continue existing in recent
34:40 decades scientists have been desperately
34:42 looking into the dim depths of space in
34:44 search of a Haven for life so far none
34:47 of the exoplanets we've found have
34:49 refuted the hypothesis of the uniqueness
34:52 of life but what if we're simply looking
34:54 in the wrong place perhaps it's not the
34:56 planets that hold all the answers but
34:59 their
35:00 moons in the mystical deep space
35:03 exomoons are unlike any other satellite
35:05 in the solar system the size of our
35:08 Earth these hidden Giants have an
35:10 amazing feature life can be found in
35:13 their interior many times more often
35:16 than on ordinary
35:17 exoplanets today we'll dive into the
35:20 mysterious distant universe and try to
35:24 discover why exom moons May someday
35:27 change
35:29 Humanity let's go back to the very
35:32 beginning of the history of exoplanet
35:34 science since astronomy received a
35:36 strong impetus only in the middle of the
35:38 20th century scientists began to study
35:41 the first exoplanets not so long ago the
35:44 first confirmed exoplanets were recorded
35:46 in
35:47 1992 it was a group of Earth Mass
35:49 planets orbiting the Pulsar PSR b257
35:54 +2 just 3 years later scientists found
35:58 the first planet orbiting the star 51
36:00 pegasi similar to our sun this was the
36:04 birth of exoplanetary science which is
36:06 dedicated to the study of planetary
36:08 systems outside our solar system and in
36:12 addition the search for places where
36:14 humanlike life could originate other
36:17 exoplanets available in our visible
36:19 Universe didn't have to wait long either
36:22 in the following years astronomers found
36:24 several more exoplanets until in 20 9
36:28 the Kepler space telescope was sent to
36:30 explore outer space in just 5 years of
36:33 operation it was able to confirm about
36:36 715 exoplanets with a size and
36:40 conditions similar to Earth's as of now
36:43 we already know about more than
36:45 5,500 planets outside the solar system
36:49 and the recently sent James web
36:50 telescope likely to be able to show us
36:52 even more distant planets further in
36:55 2013 scientists were able to determine
36:58 the planet's color for the first time
37:00 and a year later they were able to
37:02 record the magnetic field and later
37:05 volcanic activity finally in 2018
37:08 astronomers made a new potentially
37:10 breakthrough Discovery for the first
37:13 time a possible exomoon was recorded
37:15 near the Planet Kepler
37:18 1625b while this may not seem like such
37:20 an incredible Discovery at first glance
37:22 exomoons open a new chapter in modern
37:25 astronomy not only is novel hitherto
37:28 unexplored space objects but also as
37:31 potential elements for supporting life
37:33 on exoplanets and satellites themselves
37:36 every year knowledge about distant dim
37:39 exoplanets deepens bringing scientists
37:42 closer to a complete picture of the
37:44 history of the entire universe but how
37:47 did the scientists manage to confirm so
37:49 many planets in such a short time when
37:51 it's impossible to take a photo of each
37:53 one only 69 planets were found with
37:56 images the most Compu method is the
37:58 transit method which you may already
38:01 know when an exoplanet passes by its
38:03 Central Star the same star becomes
38:06 slightly dimmer which reveals the
38:08 presence of an object orbiting it
38:10 although this method doesn't allow us to
38:12 directly observe the planet and may turn
38:14 out to be just a glitch it is currently
38:17 the most effective of
38:19 all exoplanet exploration plays a
38:22 crucial role in all of astronomy and the
38:25 future of all of humanity exomoons as a
38:28 new chapter in exoplanet science may
38:31 have great potential for the search for
38:33 extraterrestrial life however despite
38:37 this exos satellites are of not much
38:39 interest to current research the main
38:42 problem associated with the search for
38:43 these exoplanets is their elusiveness to
38:47 telescope radar although no scientists
38:50 deny that some exoplanets may have
38:52 satellites it's an extremely difficult
38:55 and to some extent even impossible ible
38:57 task for our current Technologies to
39:00 investigate them the transit method or
39:03 more precisely the method of studying
39:06 the shift in the spectrum of stars can
39:08 confirm an exoplanet but a satellite
39:11 orbiting it almost under no
39:13 circumstances unless for example the
39:16 spacecraft is in the closest possible
39:17 proximity to the object of observation
39:19 due to a completely insignificant change
39:22 in the brightness of the star thus even
39:25 the very first exomoon found by Kepler
39:27 and the ones discovered later near the
39:29 planets Kepler 1708b and Kepler
39:33 1513b are still not perceived as
39:35 full-fledged proof of their existence
39:38 and therefore there is a possibility
39:40 that it could be just some kind of
39:41 technical error during the observation
39:44 which is not so far from the truth since
39:46 further observations did not yield any
39:48 encouraging results however as in the
39:50 case of the giant planet satellite
39:52 Kepler
39:54 1625b an exomoon can be seen if it is
39:57 large enough so far the first
39:59 hypothetical exomoon could be the size
40:01 of the Earth and have a strange tilted
40:04 orbit like Neptune's moon
40:07 Triton such a huge size of a possible
40:10 Moon may become one of the most
40:11 important elements in the further search
40:13 for other moons thus more than 20
40:16 exomoon candidates are currently known
40:19 all of them are gigantic probably at
40:22 least for Kepler
40:23 1625b it's the star around which it
40:26 orbits it is a red giant this dying star
40:30 can haat the moon's atmosphere
40:32 increasing its effective diameter and
40:34 allowing scientists to detect satellites
40:37 more often however perhaps right now
40:40 exomoons are not of too much scientific
40:43 importance for scientists to invest a
40:45 lot of resources in developing
40:46 Technologies to find them at this stage
40:49 of our science exomoons don't seem to be
40:51 a higher priority than other space
40:54 objects such as exoplanets the SAT ites
40:57 of distant planets are too complex to
41:00 study and have a very high chance of a
41:02 false positive result therefore it may
41:05 take months or even years of observation
41:07 and Analysis to confirm one satellite
41:11 when it seems more rational to spend
41:13 this resource on exploring a planet with
41:15 potential support for life including
41:18 human life of course it is possible that
41:21 exomoons may hide life in their interior
41:24 but Alternatives in the form of Rocky
41:26 EXO planets like Earth are still of much
41:29 higher importance in scientific
41:32 circles but we're going to focus on the
41:34 exomoons themselves and try to
41:36 investigate them is there any need to
41:38 study these mysterious and hidden moons
41:41 at all in fact these moons contain a lot
41:44 of information for our complete
41:46 understanding of the structure of the
41:47 universe but this will only be possible
41:50 in the future wellbe it not in the near
41:52 future the first thing that draws
41:54 scientists attention to even just
41:56 candidates for ex moons is their size
41:59 the largest moon in the solar system
42:02 ganim meat orbiting Jupiter has a
42:04 diameter of
42:06 3,273 Mi or
42:09 5,268 km but recorded exomoons can reach
42:13 the size of the Earth or even Neptune
42:16 therefore since such moons are even
42:19 difficult to distinguish among
42:21 exoplanets it's incredibly exciting to
42:23 imagine what moons might look like and
42:25 what activity they exhibit
42:28 it's possible that some large exomoons
42:31 have many of the features of planets and
42:33 that their study could overturn
42:34 everything we know about
42:36 satellites their similarities to other
42:39 exoplanets such as their likely geologic
42:42 activity bring us to the next important
42:44 point for careful study in the future
42:46 and that is the support of life we know
42:50 that several moons of the solar system
42:52 such as Enceladus or Europa despite
42:54 their low surface temperatures and small
42:57 eyes could hypothetically be a Haven for
43:00 living organisms due to the presence of
43:02 global oceans however what about the
43:04 much more massive moons which not only
43:07 can support a dense atmosphere but also
43:09 have more access to building chemicals
43:11 both from the inside and
43:13 outside according to a study by the
43:15 University of Washington exom moons have
43:18 more potential to support life than even
43:21 exoplanets they also have a habitable
43:23 zone although it's slightly different
43:26 but the main argument for exomoons as
43:28 one of the most intriguing places for
43:30 life to exist is the availability of
43:33 several heat sources for them the First
43:36 Source is the star itself and the second
43:39 is their Planet the moons are heated by
43:41 the gravitational pull of the planet
43:43 which keeps the probable water in the
43:45 interior of the Moon in a liquid state
43:48 moreover heating from an exoplanet can
43:51 stimulate geological activity such as
43:53 volcanic eruptions creating enough gas
43:55 inside the Moon to maintain an
43:58 atmosphere for a long time and also
44:01 bringing various crucial chemical
44:02 elements to the surface so exomoons are
44:06 not as simple as they may seem perhaps
44:09 the difficulty of finding them will be
44:11 rewarded with a potential breakthrough
44:13 in science finally exomoons may become
44:16 the necessary tool to study the
44:18 formation of our universe thus the
44:21 analysis of exomoons near different
44:23 stars and planets can reveal to
44:25 scientists how space objects are formed
44:27 what factors are responsible for
44:29 supporting life and what the history of
44:31 other planetary systems is in general in
44:35 particular comparing the moons of the
44:37 solar system with those of distant
44:39 systems can give scientists an
44:41 understanding of the specifics and
44:44 conditions of their development as well
44:45 as an approximate value of the abundance
44:48 of systems where complex intelligent
44:50 life has developed the Earth
44:52 hypothetically may be almost the only
44:55 planet on which life could have formed
44:57 at least in the visible universe and any
44:59 clues on exom moons with potentially
45:02 higher chances of supporting living
45:03 organisms can confirm or deny
45:06 this however for now deep exploration of
45:10 exomoons is only a matter of the future
45:13 on the other hand the James web Space
45:15 Telescope Mission will continue for
45:17 several more years so perhaps the hope
45:19 of finding an exomoon for the first time
45:21 in this decade is not going away
45:24 nevertheless since the search for
45:26 exomoons is an extremely difficult and
45:29 almost impossible task for our current
45:31 Technologies exomoons are likely to
45:33 become one of the drivers of
45:35 technological progress as we know the
45:37 transit method or gravitational lensing
45:40 will not help to look for micro signs of
45:42 the presence of exomoons so this factor
45:44 is already challenging scientists to
45:46 modify or even create new technologies
45:49 to capture such subtle objects but this
45:52 is a task for the near future in the
45:54 long term both intriguing moons and
45:57 exoplanets will require much more
45:59 thorough analysis including using images
46:01 and samples of the atmosphere or even
46:03 soils so if interesting candidates where
46:07 extraterrestrial life exists are ever
46:09 found then comprehensive space missions
46:12 are likely to follow advancing human the
46:15 research Focus the only step we have
46:17 left to take is to find such an
46:19 exoplanet or
46:22 exomoon in 2026 the European Space
46:25 Agency plans to send the Plato Mission
46:28 which will continuously look at several
46:31 areas in outer space to capture
46:32 transiting objects the mission will last
46:35 for 6 years and may be the one to make
46:37 this expected Discovery however the
46:40 benefits of exomoon search and
46:41 exploration do not end with a
46:43 technological breakthrough exomoons are
46:47 very valuable natural Laboratories
46:49 located near various Planet Stars
46:53 analyzing the impact of these bodies on
46:55 the moons will not only deepen what's
46:57 known about the formation of planets but
46:59 also demonstrate to scientists the
47:01 variety of conditions under which life
47:03 can develop for example traces of biome
47:07 or even techno signatures created by
47:09 civilizations on various moons can
47:12 provide a clear picture of the signs for
47:14 the development of intelligent life thus
47:17 building more prioritized paths for
47:19 future missions to the most likely
47:21 planets or Moons for aliens to live on
47:24 but for now we can only wait for the
47:26 moment when we find the first exomoon
47:28 and begin a long but life-changing
47:31 scientific and technological
47:35 Ascent exomoons despite their
47:37 invisibility and skeptical
47:39 insignificance May one day critically
47:42 change everything known to the entire
47:44 human race about our vast Universe even
47:47 a small observation can eventually
47:50 become the main driver for revolutionary
47:54 discoveries continued research will
47:56 reveal more and more answers and only by
47:59 pursuing this knowledge will the
48:01 cumbersome mysterious Cosmos One Day
48:05 become less confusing to us but in the
48:08 face of the vast Universe we must never
48:10 lose our enthusiasm for learning no
48:13 matter how difficult and distant our
48:16 desired
48:18 [Music]
48:21 outcome Saturn has captivated the human
48:25 imagination from ancient civilizations
48:27 to Modern astronomers the mauy of New
48:30 Zealand separated by vast oceans and
48:33 without telescopes somehow knew that
48:35 Saturn had Rings how the mystery
48:41 deepens Saturn has long been a symbol of
48:43 the unknown and mysterious its iconic
48:46 rings have been the subject of Wonder
48:48 and speculation since the time of
48:52 Galileo but what if we told you that
48:54 these Rings however Eternal they may
48:57 seem are actually a fleeting Cosmic
49:00 phenomenon adding to the Intrigue is a
49:03 storm twice the width of Earth with a
49:05 mysterious hexagonal shape that's raging
49:08 at Saturn's North Pole what forces could
49:11 have created such a geometrically
49:13 perfect formation but the Mysteries
49:15 don't end there Saturn's satellites
49:18 Titan and Enceladus offer conditions
49:21 that could potentially support life
49:23 Lakes of liquid methane and geysers
49:26 spewing water and organic material into
49:28 space make these satellites more than
49:31 just celestial bodies they potential
49:33 homes for
49:35 Life join us for a closer look at this
49:38 enigmatic Giant and its Cosmic
49:44 Mysteries our journey begins with
49:46 Galileo galile the Italian astronomer
49:49 who first pointed his telescope at
49:51 Saturn in
49:52 1610 what he saw puzzled him a planet
49:56 with something like ears he didn't
49:58 realize he was looking at the edges of
50:00 Saturn's magnificent Rings a feature
50:02 that would puzzle astronomers for
50:04 centuries to come Galileo's telescope
50:07 was primitive by today's standards and
50:10 the true nature of Saturn's ears
50:12 remained a
50:13 mystery it was not until 1655 that
50:17 Christian hens armed with a more
50:19 advanced telescope correctly identified
50:21 them as a system of rings surrounding
50:23 the planet
50:26 moving into the modern era we witnessed
50:28 the pioner 11 Mission the first
50:31 spacecraft to fly past Saturn in
50:34 1979 this Mission provided us with the
50:37 first close-up images of the planet and
50:39 its rings revealing intricate details
50:42 that were once inaccessible to Earth's
50:44 telescopes and
50:46 us but it was the Cassini mission that
50:48 truly revealed Saturn in all its Glory
50:52 launched in 1997 and arriving at Saturn
50:55 in 2004 Cassini spent 13 years studying
50:59 the planet its rings and its satellites
51:02 from discovering plumes of water ice on
51:05 Enceladus to capturing the Ethereal
51:08 beauty of a hexagonal shaped storm at
51:11 Saturn's North Pole Cassini
51:13 revolutionized our understanding of this
51:16 distant
51:17 world and here's an interesting point
51:20 long before the Advent of telescopes the
51:22 mie people of New Zealand had myths that
51:25 described Saturn as having a pararo or
51:27 belt around it how they knew this
51:30 remains a matter of debate and
51:32 speculation but as we'll see later
51:34 Saturn holds more than one mystery what
51:37 do you think could have created a
51:38 hexagonal storm with an area larger than
51:41 the Earth
51:46 itself Saturn Harbors a geometric enigma
51:49 at its North Pole a six-sided storm
51:52 that's puzzled scientists for decades
51:55 this six-sided wonder is not just a
51:57 superficial feature but a deep and
51:59 enduring mystery that breaks down the
52:02 understanding of fluid dynamics and
52:04 planetary atmospheres the hexagon was
52:07 first discovered in 1981 by the Voyager
52:11 spacecraft but it wasn't until the
52:13 Cassini Mission which orbited Saturn
52:15 from 2004 to 2017 that we got a front
52:19 row seat to this Cosmic spectacle
52:22 cassini's highresolution images showed a
52:24 symmetrical jet stream surrounding the
52:27 hurricane likee vortex at the center of
52:29 the hexagon unlike Earth's chaotic
52:32 weather systems Saturn's hexagon is a
52:35 masterpiece of geometric Precision so
52:38 what's causing this hexagonal storm
52:41 researchers at Harvard University have
52:43 developed a 3D model that suggests deep
52:45 thermal convection in Saturn's outer
52:47 layers may be the culprit this model
52:50 shows that the storm could spread
52:52 thousands of kilometers deep into
52:54 Saturn's atmosphere well be beyond what
52:56 we can
52:57 see interestingly scientists have been
53:00 able to reproduce the hexagonal pattern
53:03 in a laboratory setting although these
53:05 experiments do not capture all the
53:07 nuances of Saturn's complex atmosphere
53:10 they provide a glimpse of
53:12 extraterrestrial
53:13 phenomena Saturn's hexagonal Vortex
53:16 contrasts sharply with Earth's polar
53:19 vortex which is irregular and less
53:21 stable this difference raises questions
53:24 about the fundamental properties that
53:26 distinguish the atmospheres of the gas
53:28 giants from the earth group
53:31 planets the longevity of the hexagon is
53:34 another mystery it's been observed for
53:36 at least four decades and possibly much
53:39 longer this steady feature suggests that
53:43 everything that feeds the hexagon is not
53:45 a temporary phenomenon but a stable
53:48 perhaps even permanent aspect of
53:50 Saturn's internal Dynamics
53:57 let's shift our attention from The
53:58 Mystery of the hexagon to another Wonder
54:01 of Saturn Saturn's rings are more than
54:04 just Celestial jewelry they're Dynamic
54:07 everchanging systems that interest
54:09 astronomers and the public
54:11 alike but what are these rings made of
54:14 and why are they so
54:17 shortlived Saturn's rings are composed
54:20 mostly of water ice with a mixture of
54:22 dust and Rocky material they range in
54:24 size from tiny particles to huge chunks
54:28 the size of houses these ice particles
54:30 are not static they're in constant
54:33 motion under the influence of Saturn's
54:35 gravity and the gravitational pull of
54:37 its
54:38 satellites the Rings are divided into
54:40 several subdivisions and gaps each with
54:43 its own unique characteristics most
54:46 notable are the a b and c Rings
54:49 separated by gaps such as the Cassini
54:51 ring a gap 3,000 Mi between the A and B
54:55 rings
54:58 the origin of Saturn's rings has been
55:00 the subject of
55:02 debate one popular Theory suggests that
55:05 they formed from the remnants of a
55:06 shattered
55:07 Moon another theory states that they're
55:09 the remnants of material from the
55:11 formation of the solar system captured
55:13 by Saturn's gravitational
55:16 pull Recent research has also shown that
55:18 the Rings may be much younger than
55:20 Saturn itself perhaps around 400 million
55:23 years old based on the rate of dust
55:25 contamination
55:28 Saturn's rings don't last forever
55:30 they're slowly disappearing because of a
55:32 phenomenon known as ring
55:35 rain in which ring particles are drawn
55:37 into Saturn's atmosphere this process is
55:40 accelerated by microm meteoroid
55:43 bombardment and interaction with
55:45 Saturn's magnetic
55:47 field at the current rate some
55:49 scientists predict that Saturn's rings
55:51 could disappear within 100 million
55:54 years the de of the Rings would not only
55:57 change Saturn's appearance but could
55:59 also have consequences for its
56:01 atmosphere and magnetic
56:03 field as we pause for a moment we
56:06 realize that even the most fascinating
56:08 features of our universe are not immune
56:10 to the inexorable forces of physics
56:13 doomed to disappear into the chronicle
56:15 of
56:20 Eternity Saturn the ringed giant of our
56:24 solar system is not just a Celestial
56:26 Wonder it's also a cosmic playground
56:30 that contains some of the most
56:31 intriguing
56:33 satellites two of which Titan and
56:35 Enceladus have fascinated scientists and
56:38 sparked debate about the potential for
56:40 life beyond
56:42 Earth Titan Saturn's largest satellite
56:45 is a world shrouded in
56:47 mystery its dense atmosphere is rich in
56:50 organic compounds and there are lakes
56:52 and rivers of liquid methan on the
56:55 surface but but what's truly amazing is
56:57 Titan's rate of removal from
57:00 Saturn 100 times faster than previously
57:03 thought amounting to a staggering 4.3 in
57:07 per
57:08 year this rapid drift suggests a dynamic
57:11 and evolving relationship between Titan
57:14 and Saturn could this drift affect
57:16 Titan's internal
57:18 Dynamics and perhaps even its potential
57:21 for the existence of
57:23 Life an atmosphere rich in organic comp
57:26 compounds such as nitrogen and methane
57:28 and the possibility of an underground
57:30 ocean make Titan a tempting Target for
57:32 the search for extraterrestrial life but
57:35 the question remains What would life
57:38 look like in an environment so radically
57:40 different from
57:42 Earth's and let's remember Enceladus
57:44 another satellite of Saturn that's very
57:47 different from Titan it's an icy world
57:50 with a highly reflective surface that
57:52 outshines any other body in the solar
57:54 system
57:56 Enceladus takes the concept of an ocean
57:58 world to a new level not only does it
58:01 have a subsurface ocean but it also
58:03 sprays it into space where samples of it
58:07 can be collected by a space
58:09 probe this ocean contains most of the
58:12 chemical ingredients necessary for life
58:14 including hot mineral-rich water
58:17 erupting from hydrothermal
58:19 vents hydrothermal vents can provide the
58:22 necessary conditions for Life as We Know
58:24 It On Earth Earth these vents are
58:27 teeming with life forms that thrive in
58:29 extreme
58:31 conditions could enceladus's vents be
58:34 home to similar but alien life
58:37 forms Enceladus also contributes to
58:40 Saturn's z-ring a unique characteristic
58:43 that further enriches the dynamic
58:45 relationship between the Moon and its
58:47 host Planet the icy particles in this
58:50 ring open a window into the moon's
58:52 internal chemistry providing clues that
58:55 may reveal its
58:58 Secrets Titan and Enceladus are two
59:01 moons orbiting the same Planet but quite
59:04 different in their
59:05 characteristics both present compelling
59:07 arguments in favor of the potential for
59:09 Life fueling our
59:13 curiosity as we Ponder the possibilities
59:16 of life on Saturn satellites it's worth
59:19 noting that our curiosity is not limited
59:21 to telescopes and computer modeling
59:24 upcoming missions aim to study these
59:26 ites up close and perhaps answer some of
59:28 our most pressing
59:30 questions meet dragonfly NASA's
59:33 ambitious mission to Titan scheduled for
59:37 launch in the 2030s this rotorcraft will
59:40 fly over Titan's diverse terrain from
59:43 Dunes to impact
59:45 craters dragonfly's main goal is to
59:47 search for the building blocks of life
59:50 it will analyze complex organic
59:52 compounds in the atmosphere and on the
59:54 surface providing invaluable data on
59:57 Titan's
59:58 chemistry equipped with a suite of
60:00 scientific instruments dragonfly seeks
60:03 to understand the geologic processes on
60:05 the moon and how they relate to its
60:07 potential for Life Could Titan's unique
60:11 chemical composition and liquid methane
60:13 Cycles offer a different recipe for
60:16 Life although no missions to Enceladus
60:19 are currently planned the moon's
60:21 potential for life has made it a prime
60:23 candidate for future exploration
60:26 scientists are proposing missions that
60:28 could fly through enceladus's plumes and
60:30 directly sample its underground ocean
60:33 such a mission could analyze the
60:35 chemistry of the plumes in search of
60:37 signs of life or pre-biotic chemistry
60:40 the presence of hydrothermal vents in
60:43 enceladus's oceans adds another layer of
60:46 intrigue suggesting an environment in
60:49 which life could potentially
60:52 Thrive despite the technical challenges
60:55 a mission to Enceladus could
60:57 revolutionize our understanding of the
60:59 potential for life in the solar system
61:02 it could provide direct evidence for the
61:04 existence of extraterrestrial life or at
61:07 least provide clues to the conditions
61:09 necessary for life to
61:14 [Music]
61:16 exist as we mentioned Saturn's rings
61:18 don't last forever as we once thought
61:21 recent Studies have shown that a process
61:23 that can last hundreds of millions of
61:25 years is causing these icy wonders to
61:28 slowly fade away but what significance
61:31 does this have for Saturn and its
61:33 complex atmospheric
61:35 Dynamics according to a study by the
61:37 Japan Aerospace Exploration Agency this
61:41 material composed mostly of water causes
61:44 a decrease in electron density in
61:46 Saturn's
61:47 atmosphere this phenomenon known as ring
61:50 rain significantly affects Saturn's
61:53 atmospheric
61:54 conditions ring rain is not just a
61:57 trickle it's a stream that carries away
61:59 water and amounts equivalent to an
62:01 Olympic-sized swimming pool every half
62:04 hour compounding the mystery is the
62:07 relative youth of Saturn's
62:09 rings although Saturn itself is about
62:12 4.6 billion years old data from NASA's
62:15 Cassini Mission suggests that the Rings
62:18 may be only a few hundred million years
62:21 old this leads us to wonder if Saturn's
62:24 rings are so young what catastrophic
62:27 event could have led to their
62:29 formation was it the destruction of a
62:31 moon or perhaps the capture of a passing
62:35 Comet cassini's space dust analyzer has
62:39 added another layer of complexity over
62:42 13 years it's collected 163 dust
62:46 particles that came from outside the
62:48 Saturn system surprisingly the Rings
62:51 turned out to be quite clean suggesting
62:53 that they hadn't existed long enough to
62:55 to accumulate excess Cosmic
62:58 dust this cleanliness raises the
63:01 question if the Rings are young why
63:04 haven't they collected more Cosmic
63:06 dust the absence of cosmic dust in the
63:09 Rings challenges our understanding of
63:11 their age and their interaction with the
63:13 wider Cosmic
63:15 environment it's as if the Rings are in
63:17 a cosmic laboratory room or clean room
63:21 isolated from the dust that permeates
63:23 the rest of the solar system
63:26 as the Rings are depleted Saturn's
63:28 appearance will undergo a dramatic
63:31 transformation these rings have been the
63:33 planet's homework their disappearance
63:35 would not only change Saturn's
63:36 appearance but could also have unknown
63:38 consequences for its atmosphere perhaps
63:41 even affecting the planet's albo and
63:43 heat
63:44 retention the loss of the Rings could
63:47 have a cascading effect on Saturn's
63:49 atmosphere potentially altering wind
63:51 patterns and even affecting the planet's
63:54 iconic storms
63:56 the full extent of these changes is
63:57 still unknown making them a subject of
64:00 intense scientific
64:03 interest interestingly the fate of
64:05 Saturn's rings may be inextricably
64:07 linked to its
64:09 satellites some theories suggest that
64:11 gravitational instability may have
64:13 destroyed some of the icy satellites
64:15 orbiting Saturn providing enough
64:17 material to form the
64:20 Rings Saturn's rings and satellites are
64:22 like Partners in a cosmic dance each
64:26 affecting the other in subtle but
64:28 significant
64:29 ways as we continue to study these
64:32 celestial bodies we can say
64:35 unequivocally that the fate of one Can
64:38 Shed light on the mysteries of the
64:45 other our universe hides a mystery
64:48 that's long captivated the human mind a
64:51 question that Bridges the gap between
64:53 the known and the unknown the simple and
64:56 the
64:57 complex here on Earth life thrives in a
65:00 continuous movement of order and chaos
65:03 every form of life is evidence of a
65:05 hidden order a pattern woven into the
65:09 very fabric of existence from the
65:12 smallest microorganisms to the largest
65:15 mammals but what if the complexity of
65:18 Life the very essence of our existence
65:21 could be explained not only through the
65:23 lens of biology but also through a
65:25 mathematical
65:27 framework this is the territory of
65:29 assembly Theory a groundbreaking concept
65:32 that transcends traditional
65:34 science it's a journey into a world
65:37 where math and biology converge to
65:40 reveal the hidden architecture of
65:43 Life imagine a universe in which the
65:45 secrets of life from the simplest
65:48 molecule to the most complex organism
65:51 are encoded in mathematical language and
65:53 are waiting to be decoded where the the
65:55 line between living and non-living is
65:57 blurred giving birth to new
66:00 possibilities and new
66:02 understanding let's explore how this
66:04 revolutionary idea is changing our
66:07 perception of Life Evolution and the
66:10 cosmos itself and maybe we can even get
66:13 closer to answering the ultimate
66:15 question what is the true nature of life
66:17 in the
66:19 universe since the dawn of civilization
66:22 mathematics has been the language of the
66:24 universe tool for deciphering the
66:26 mysteries of nature but how does this
66:29 language of numbers and equations relate
66:32 to understanding the very essence of
66:35 life at its core assembly Theory offers
66:38 a simple but profound idea the
66:40 complexity of life can be measured and
66:43 understood through a mathematical
66:46 prism think of Life as a jigsaw puzzle
66:49 where each piece represents a molecular
66:51 building block assembly Theory seeks to
66:53 show how these pieces come to together
66:56 step by step to form the complex
66:58 structures that Define living
67:01 organisms each step in this assembly
67:03 process represents a leap of complexity
67:06 from simple atoms to complex
67:09 proteins the theory introduces the
67:11 concept of the assembly index the
67:14 assembly index the Cornerstone of this
67:16 Theory measures the number of steps
67:19 required to build a biological structure
67:21 it's a numerical value that captures the
67:24 essence of complexity by quantifying the
67:28 immeasurable but how does the standard
67:31 model of physics fit into this this
67:34 standard model Theory of physics
67:36 describes the fundamental particles and
67:38 forces that govern our universe it seems
67:41 completely separate from the
67:42 complexities of biology however assembly
67:45 Theory Bridges this
67:47 Gap in the field of assembly Theory the
67:50 standard model lays the foundation for
67:53 understanding forces and interactions
67:55 it's a bridge between the microscopic
67:57 world of quarks and leptons and the
67:59 macroscopic world of living
68:02 things another important element of the
68:04 theory is the concept of studying
68:07 dynamical systems phase space this is a
68:10 mathematical concept used to describe
68:12 all possible states of a system in the
68:15 context of assembly Theory phase space
68:18 allows us to map the path of the
68:20 Assembly of life from a single point
68:23 representing the simplest form of life a
68:25 space expands branching out into almost
68:28 infinite
68:30 possibilities each pathway representing
68:32 a different root that life can
68:34 take in this Limitless mathematical
68:37 landscape the paths of evolution and its
68:40 complexities
68:42 unfold this mathematical framework gives
68:45 us a new perspective on the complexity
68:47 of life it's not just about the
68:49 particles and forces described by the
68:50 standard model but how these elements
68:53 combine and interact act over time to
68:56 create the diverse pattern of life we
68:58 see around us this is where the chaos of
69:02 random molecular interactions gives way
69:04 to the order of living structures so
69:07 let's ask ourselves this question are
69:09 the complexities of Life simply the
69:11 product of chance or is there a deeper
69:19 cause let us consider two sharply
69:22 contrasting Concepts complexity and
69:26 entropy entropy a measure of disorder
69:30 and Randomness seems to be at odds with
69:32 the complexity we observe in life how do
69:35 these opposing forces coexist in the
69:37 natural world it's here that assembly
69:39 Theory offers a revolutionary
69:42 perspective so Central to assembly
69:45 theory is the assembly index a
69:47 revolutionary tool designed to measure
69:50 the complexity of Life think of it as a
69:52 cosmic ruler measuring the steps
69:54 required to assemble a biological
69:56 structure from its simplest
69:58 components imagine a single molecule as
70:01 the starting point on this scale As you
70:03 move up the scale each step represents a
70:06 more complex assembly from molecules to
70:09 cells and Beyond the higher the index
70:13 the greater the complexity and the less
70:15 likely it is that the structure could
70:17 have Arisen by
70:19 chance now let's delve into the
70:21 interaction between entropy and
70:24 complexity and entropy a concept rooted
70:26 in thermodynamics suggests that systems
70:29 naturally tend toward disorder however
70:32 life defies this tendency evolving from
70:36 simple Origins to a variety of forms
70:39 combined into the complex ordered
70:40 structures we see
70:42 today how does assembly Theory resolve
70:46 this apparent
70:47 contradiction it suggests that life is
70:50 inherently a process of overcoming
70:52 entropy through the lens of the assembly
70:54 index we see the complexity of life is
70:57 not a challenge to entropy but a journey
70:59 through
71:00 it consider the early Earth a primordial
71:04 soup of simple
71:06 molecules over Millennia driven by the
71:08 laws of physics and chemistry these
71:10 molecules began to assemble into more
71:13 complex structures each step along the
71:15 way marked a victory over entropy a step
71:18 toward greater complexity in life
71:21 rethinking Evolution through assembly
71:23 Theory we see it not as a mere
71:25 biological process but as a mathematical
71:29 inevitability the emergence and
71:31 evolution of life became a story of
71:32 increasing complexity a story written in
71:35 the language of
71:37 [Music]
71:42 mathematics let us now turn to a very
71:44 trivial question but one that shines in
71:46 a new light are we
71:50 alone the search for extraterrestrial
71:52 life has captivated our imagination for
71:54 centuries
71:56 now thanks to assembly Theory we have a
71:59 new tool in this Cosmic Quest assembly
72:02 Theory offers a unique approach to
72:04 detecting alien life it's not about
72:07 scanning the sky for radio signals or
72:09 analyzing light Spectra for the presence
72:12 of oxygen instead it's about
72:14 understanding the complexity of
72:16 molecules and structures that may
72:18 indicate
72:19 life imagine scanning the atmosphere of
72:21 a distant exoplanet or the surface of a
72:24 moon in our Solar system using assembly
72:27 Theory we could analyze the molecular
72:29 complexity of the samples in search of
72:31 patterns that indicate the presence of
72:34 Life the higher assembly index the more
72:37 likely it is that these molecules are
72:39 the result of life rather than random
72:43 processes however the road to
72:45 discovering alien life is full of
72:47 challenges and limitations one of the
72:49 biggest obstacles is our understanding
72:51 of life itself our definition of life is
72:54 based on what we know life on Earth what
72:58 if it doesn't meet our biochemical
73:01 standards another problem is the
73:03 vastness of space the universe is vast
73:07 and our ability to explore it is limited
73:09 by current technology even with the most
73:12 sophisticated telescopes and probes we
73:14 can only analyze a tiny fraction of the
73:17 cosmos moreover assembly Theory while
73:20 powerful is still in its infancy it's a
73:23 new approach and its application to the
73:25 search for extraterrestrial life as
73:27 Uncharted
73:28 Territory there are questions about its
73:30 applicability and accuracy in different
73:33 environments especially those that are
73:35 very different from terrestrial
73:37 environments despite these problems the
73:40 potential of assembly theory in the
73:41 search for alien life is enormous it
73:44 could redefine our understanding of life
73:47 in the universe opening new doors in
73:54 astrobiology so assembly Theory offers a
73:56 new way of looking at life not just as a
73:58 biological phenomenon but as an emergent
74:01 property of cosmic
74:03 complexity imagine the early days of our
74:06 planet a world in motion a crucible for
74:09 the chemistry of life here in this
74:12 chaotic environment simple molecules
74:14 began the Journey of assembly a process
74:17 governed by the laws of physics and
74:18 chemistry but leading to something much
74:21 deeper life according to assembly Theory
74:24 Emer emerges when these molecular
74:26 structures reach a level of complexity
74:28 that allows them to store and reproduce
74:31 information this is where chemical
74:33 memory a crucial step in the evolution
74:35 of Life comes into
74:37 play chemical memory is the ability of
74:40 certain molecular structures to retain
74:43 structure in other words we can say this
74:46 is the blueprint for
74:48 life in the world of assembly Theory
74:51 this is where reproducibility becomes
74:53 key the abil ability to reproduce these
74:56 patterns to pass them on from generation
74:58 to generation is what drives the
75:00 evolution of
75:02 life from the simplest RNA molecules in
75:05 the primordial soup to the vast
75:07 diversity of life we see today each step
75:11 in this evolutionary Journey has been a
75:13 step up the assembly index each increase
75:17 in complexity represents a triumph over
75:19 the entropy that governs the
75:22 universe but the story of the origin and
75:25 evolution of life is not just a story of
75:27 increasing complexity it's also a story
75:29 of resilience and
75:32 adaptability life has found a way to
75:34 thrive in the most extreme environments
75:36 from the depths of the ocean to the
75:39 fringes of
75:44 space in the realm of scientific
75:47 discovery every new theory is
75:48 scrutinized and debated assembly Theory
75:51 a concept that promises to revolutionize
75:54 our understanding of life and complexity
75:57 now stands at a Crossroads being
75:59 questioned by critical voices such as Dr
76:01 Hector zenel the critique presented by
76:04 zenel raises fundamental questions about
76:06 the future evolution of assembly Theory
76:08 covering an impressive 18,000 words the
76:11 article will require time and thought
76:14 taking approximately 1 to two hours of
76:16 dedicated
76:17 reading this is not a cursory look at
76:19 the topic but a deep dive into the heart
76:22 of the scientific debate for those who
76:25 are interested we leave a link in the
76:26 description to both articles the study
76:29 and the counterarguments to
76:31 it looking to the Future the role of
76:34 assembly theory in scientific research
76:36 remains uncertain will it be able to
76:39 adapt and overcome these challenges or
76:42 will it remain a footnote in the history
76:44 of
76:45 science despite the disagreements one
76:47 thing is clear the debates surrounding
76:49 assembly Theory have initiated a
76:51 conversation about the nature of
76:53 scientific discovery they emphasize the
76:55 need for transparency rigor and humility
76:59 in pursuing
77:01 knowledge in the end the impact of
77:04 assembly theory on future research may
77:06 not lie in its specific claims but in
77:08 the lessons it teaches us about the
77:10 scientific
77:12 process as we explore the mysteries of
77:15 life in the universe such theories will
77:17 come and go but the Quest for
77:20 understanding the quest to unlock the
77:23 mysteries of our existence
77:25 will always remain at the center of the
77:27 interest of scientific
77:37 research imagine a single point just a
77:40 spec of light hovering in an Endless Sea
77:43 Of Darkness it's not just a random dot
77:47 it's our home Earth but what if we told
77:50 you that this dot is just a fleeting
77:53 moment in a cosmic pan orama so vast and
77:57 complex that it defies human
78:00 comprehension imagine a night sky
78:03 decorated with stars each representing a
78:06 sun many of which have their own planets
78:08 now multiply that image by 100 billion
78:12 even in this case you've barely touched
78:14 the surface beyond our Earth beyond our
78:18 sun even beyond our galaxy lies a
78:21 structure so vast that everything you
78:24 know seems like a single thread in an
78:27 unfathomable Cosmic web the human mind
78:30 which is itself a Marvel struggles to
78:32 grasp this scale our brains are built to
78:35 comprehend the Rises and slopes of
78:37 mountains and the vastness of oceans but
78:40 how do we comprehend a structure that
78:41 stretches billions of light years today
78:44 we're on a journey to explore these
78:46 Galactic threads the senu and muscles of
78:49 the universe itself we will venture into
78:52 a realm of the almost incomprehensible
78:54 where even the speed of light seems
78:58 pedestrian spiners weave intricate webs
79:02 thin but strong each thread connected to
79:06 the other in a complex pattern
79:09 architects of nature create these webs
79:11 to survive capture prey and probe the
79:16 environment now imagine a web woven not
79:19 by spiders but by the very fabric of
79:22 space and time itself a web that links
79:26 galaxies star clusters and dark matter
79:29 into a complex web this is the cosmic
79:33 web the grand architecture of our
79:37 universe each node you see here is not a
79:40 single star or Planet but an entire
79:43 galaxy a colossal cluster of billions of
79:46 stars planets and other celestial
79:48 objects Bound by gravity but what gives
79:52 this network this structure the answer
79:55 lies in something we can't even see Dark
79:58 Matter dark matter which scientists
80:01 believe makes up about 27% of the
80:03 universe acts as the framework on which
80:06 this web is built although invisible its
80:08 presence is felt through the
80:09 gravitational pull that determines the
80:11 formation of galaxies and the paths they
80:14 take the cosmic web was not always as we
80:17 see it today it evolved over billions of
80:21 years beginning with tiny fluctuations
80:24 in the density of the early Universe
80:27 these fluctuations grew pulled together
80:30 by gravity eventually forming the
80:32 Majestic filaments and nodes we now
80:35 see one of the most impressive examples
80:38 of a galactic filament is the Great Wall
80:41 of Hercules Northern Corona this
80:44 colossal structure spans a distance of
80:46 up to 23 billion Lighty years making it
80:49 one of the largest known structures in
80:51 the
80:53 universe understanding this network is
80:55 not just an academic exercise it's a
80:57 quest to understand our place in the
81:00 universe are we simply an accidental
81:03 byproduct of cosmic Evolution or is
81:06 there a grander design at work
81:09 here scientists use a range of tools to
81:12 study this network from telescopes that
81:15 can see distant galaxies to simulations
81:18 that model the behavior of Dark Matter
81:20 each Discovery is a piece of a puzzle a
81:23 thread of a story that spans the entire
81:28 universe here it is Earth a pearl of
81:32 blue and green suspended in the vastness
81:35 of space a planet teaming with life from
81:39 microscopic to
81:41 magnificent it's easy to think of the
81:43 earth as the center of everything but in
81:45 the grand scheme of the universe it's
81:47 just a
81:49 spec in our solar system alone Earth is
81:52 only one of eight planets orbiting this
81:54 sun and yet it stands out for its unique
81:57 ability to support life the oceans the
82:01 atmosphere the magnetic field all these
82:03 elements are in delicate balance zoom
82:06 out even further and our entire solar
82:09 system becomes a tiny dot in one of the
82:12 Spiral arms of the Milky Way galaxy a
82:14 Galaxy that's home to hundreds of
82:16 billions of stars each potentially
82:18 containing its own system of planets in
82:21 the Milky Way it's just one Galaxy in a
82:24 COS Cosmic web of hundreds of billions
82:26 of galaxies each of these galaxies is a
82:29 node a focal point in this unimaginable
82:33 structure even within our galaxy the
82:36 Earth is influenced by forces Beyond its
82:38 control Dark Matter the invisible
82:41 backbone of the cosmic web shapes the
82:43 structure of the Galaxy and as a result
82:46 the environment around the earth yet
82:49 despite its seemingly insignificant
82:51 place in the cosmos Earth is unusual for
82:54 one reason it has life it's the only
82:58 known Celestial body where life not only
83:01 originated but has evolved to an
83:03 incredible level of diversity and
83:06 complexity Humanity's quest to
83:09 understand its place in the universe has
83:10 led to remarkable scientific advances
83:13 telescopes peer into remote corners of
83:16 the universe and supercomputers simulate
83:18 the cosmic web helping to answer
83:20 fundamental questions about the nature
83:22 of reality
83:27 for example look at the sun the Blazing
83:30 ball of plasma that lights up our sky
83:32 and warms our planet it's the reason you
83:35 can see these very images the reason
83:37 life exists on Earth but in the context
83:40 of the cosmic web the sun is just one
83:43 node a lone star among countless others
83:48 close to the sun we find other stars
83:50 some smaller and cooler others larger
83:53 and hotter
83:55 each of these stars is like a bead on a
83:57 huge Cosmic thread linked together by
84:00 gravity and dark matter our sun is
84:03 located in the Orion sleeve of the Milky
84:05 Way a small spiral arm located about
84:09 27,000 light years from the center of
84:12 the
84:12 Galaxy even within our galaxy it is far
84:16 from special just one of about 400
84:18 billion
84:20 stars in The Great expanse of the cosmic
84:23 web stars like our sun form complex
84:26 nodes that connect larger structures
84:28 such as galaxies and Galaxy clusters
84:31 they are the building blocks the
84:33 fundamental units that give the web its
84:36 shape so what powers this Celestial
84:39 Beacon the answer is nuclear fusion deep
84:42 in the sun's core hydrogen atoms Collide
84:45 and fuse to form helium releasing
84:48 massive amounts of energy this energy
84:51 not only Powers the Sun but also
84:53 balances the gravity vitational forces
84:55 trying to compress it this energy has
84:58 far-reaching
84:59 consequences it provides the Earth with
85:02 the heat and light necessary for life it
85:05 drives our weather systems Powers
85:07 photosynthesis and even influences
85:10 earth's climate over the long
85:12 term understanding the sun is crucial to
85:15 understanding The Cosmic web various
85:17 missions such as the Parker solar probe
85:20 and the Solar Dynamics Observatory have
85:23 been launched to study the sun's
85:25 behavior these missions provide insights
85:28 into solar Cycles magnetic fields and
85:30 even the future of the
85:35 sun although the sun serves as a vital
85:38 node in the cosmic web nourishing life
85:41 on Earth and influencing our local space
85:43 environment it's just one example in a
85:46 universe teaming with Stellar diversity
85:49 every Star regardless of its size or
85:51 lifespan plays a role in shaping the COS
85:54 I web from the tiniest red dwarfs to the
85:57 massive blue giants each star is a
86:00 unique knot contributing to the overall
86:03 structure of Galactic
86:06 filaments stars are often classified by
86:09 their mass and brightness and plotted on
86:11 a graph known as the herzsprung Russell
86:14 diagram this diagram shows the life
86:16 stage of a star and gives clues about
86:19 its future
86:20 fate take for example a red dwarf the
86:24 most common type of star in the universe
86:26 they're small cold Stars also called
86:29 mtype
86:31 Stars often less than half the mass of
86:33 our sun they make up for their lack of
86:35 size with longevity burning for tens to
86:38 hundreds of billions of
86:40 years red dwarfs are Frugal they turn
86:44 hydrogen into helium much more slowly
86:46 than larger Stars this slow lifestyle
86:49 allows them to be among the longest
86:51 lived objects in space now compare that
86:54 to ootype Stars the rare Titans of the
86:57 Stellar World these stars are more than
87:00 15 times more massive than the Sun and
87:03 can be a million times brighter yet they
87:06 live fast TI young often in spectacular
87:10 Supernova
87:12 explosions ootype Stars dramatically end
87:15 their lives they collapse under their
87:17 own gravity and then explode as
87:20 Supernova these explosions scatter
87:23 elements such as carbon oxygen and iron
87:26 into space promoting the formation of
87:29 new stars and
87:31 planets star clusters are like Cosmic
87:34 nurseries places where stars of
87:36 different types are born these clusters
87:39 serve as nodes in the cosmic web linking
87:41 different regions of the Galaxy and even
87:44 connecting galaxies to each other
87:46 through filaments computer simulations
87:48 help astronomers understand how
87:51 different types of stars contribute to
87:53 the cosmic Network
87:54 these virtual models can simulate
87:57 billions of years of cosmic evolution in
87:59 a matter of weeks showing how Stars
88:02 serve as the building blocks of larger
88:05 Cosmic
88:09 structures so we've already found out
88:11 stars are not Eternal they are born live
88:15 and eventually
88:17 die the life cycle of a star is a cosmic
88:20 Journey spanning billions of years a
88:23 journey that plays out key role in the
88:25 evolution of the universe and the
88:26 structure of the cosmic web the birth of
88:29 a star is a spectacle of cosmic
88:32 proportions it begins in a nebula a vast
88:35 cloud of gas and dust gravity pulls
88:38 these particles together getting denser
88:41 and hotter until nuclear fusion ignites
88:44 a new Star is Born once a star reaches
88:48 the main sequence Stage IT enters a
88:51 period of relative stability the
88:53 hydrogen and the core turns to helium
88:55 releasing energy that balances the
88:57 gravitational forces trying to compress
88:59 the star this is the longest phase of a
89:02 star's life and it's where our sun is
89:05 now but even stars like our sun must
89:08 face change in about 5 billion years the
89:12 sun will run out of hydrogen fuel its
89:14 core will shrink but its outer layers
89:16 will expand turning it into a red giant
89:20 this phase is the Prelude to the final
89:22 fate of the star depending on its mass a
89:25 star will meet one of several ends stars
89:28 with less Mass such as our sun will shed
89:31 their outer layers leaving behind a
89:33 white
89:34 dwarf more massive stars May undergo a
89:37 supernova explosion resulting in a
89:40 neutron star or black
89:43 hole these deaths are not in vain the
89:46 death agonies of stars scatter important
89:48 elements into space elements that will
89:50 become the building blocks of new stars
89:52 planets and even even
89:56 life thus the life and death of stars is
89:59 an integral part of the cycle of cosmic
90:01 creation and
90:05 destruction the cosmic web from
90:07 Individual stars to entire galaxies is a
90:11 complex network of interconnected
90:13 structures but what binds these galaxies
90:16 together what are the threads that weave
90:18 the complex fabric of the universe the
90:21 answer lies in Galaxy clusters
90:25 Galactic clusters are massive
90:27 collections of galaxies bound together
90:29 by gravitational force they may contain
90:32 only a few or thousands of galaxies and
90:35 often span millions of light years
90:38 across just as dark matter plays a role
90:40 in individual galaxies it also acts as
90:43 an invisible glue in Galactic clusters
90:47 even though we can't see it we know it
90:49 exists holding the cluster together and
90:52 forming its overall structure
90:54 within a cluster galaxies are not static
90:57 they are in constant motion some of them
91:00 may be heading toward the center of the
91:01 cluster While others may be on their way
91:03 to its Edge under the influence of
91:06 complex gravitational
91:08 interactions sometimes these
91:10 interactions can lead to dramatic events
91:13 such as Galactic collisions when
91:15 galaxies Collide Their Stars gas and
91:18 dark matter merge to form a new larger
91:22 Galaxy these events are crucial to the
91:24 evolution of Galaxy clusters and by
91:27 extension the cosmic
91:29 web but clusters are not the end of the
91:32 story they often cluster together to
91:34 form superclusters which are among the
91:37 largest known structures in the universe
91:40 these super clusters serve as the main
91:42 nodes of the cosmic web linking numerous
91:45 clusters and
91:48 filaments understanding Galaxy clusters
91:50 is the key to unlocking the mysteries of
91:53 the cosmic we
91:54 they serve as threads connecting
91:56 galaxies forming the paths along which
91:59 matter and energy flow on Cosmic
92:05 scales having studied the Colossal
92:08 structures of Galactic clusters the
92:10 threads that weave the cosmic web we now
92:13 turn our eyes to an even more mysterious
92:16 phenomenon what if there were actual
92:18 threads strings of pure energy that
92:22 stitch together the fabric of the
92:24 Universe these hypothetical
92:26 onedimensional defects in SpaceTime
92:29 could be the loose threads of the
92:31 universe remnants of the first moments
92:34 after the big
92:36 bang imagine the universe just moments
92:39 after the big bang a hot dense state of
92:43 pure
92:44 energy as the universe cooled and
92:47 expanded this energy condensed into
92:49 matter and
92:51 structure however not everything went
92:53 smoothly in some regions Kinks occurred
92:56 leading to the formation of cosmic
92:59 strings cosmic strings if they existed
93:02 would be unimaginably thin but
93:04 incredibly
93:06 dense a string less than an inch wide
93:09 could weigh as much as the
93:11 Earth they would stretch across the vast
93:14 expanse of the universe perhaps even
93:17 from one end to the other because of
93:19 their enormous Mass cosmic strings would
93:22 exert a strong gravit ational pull
93:24 affecting the motion of galaxies and
93:27 even bending light they could serve as
93:29 Cosmic highways directing the flow of
93:32 matter and energy through the universe
93:35 the search for cosmic strings continues
93:38 scientists are using a combination of
93:40 theoretical physics and observational
93:42 astronomy to search for these elusive
93:48 structures if the existence of strings
93:50 is confirmed they may become the missing
93:53 links that will help us understand not
93:55 only how the universe is organized but
93:58 also why it is organized this way
94:00 however let's return to structures of
94:02 unfathomable
94:04 scale superclusters they are the
94:07 gravitational anchors that hold together
94:10 vast networks of galaxies and Galaxy
94:13 clusters imagine moving away from our
94:16 Milky Way galaxy past our local group of
94:19 galaxies and even beyond our local Virgo
94:22 supergroup
94:23 you'll find a network of superclusters
94:26 each containing hundreds to thousands of
94:29 individual galaxies bound together in a
94:31 complex dance of gravity the
94:33 superclusters are unevenly distributed
94:36 they form a kind of cosmic skeleton
94:38 around which galaxies and Galaxy
94:40 clusters are located this skeleton gives
94:43 the cosmic web the shape that defines
94:46 the large scale structure of the
94:48 universe within the super cluster
94:51 galaxies and clusters are in con Stant
94:54 motion under the influence of the
94:55 collective gravitational pull of the
94:57 entire structure this Dynamic flow of
95:00 matter and energy is what keeps the
95:03 cosmic Network alive and Ever
95:06 Changing among the most intriguing
95:08 aspects of superclusters is the presence
95:11 of gravitational anomalies like the
95:13 great attractor these are regions with
95:16 such a strong gravitational pull that
95:18 they influence the motion of the entire
95:21 supercluster serving as the pivots of a
95:23 cosmic
95:25 web understanding superclusters is
95:28 crucial to cosmology they serve as the
95:31 largest for studying the expansion of
95:34 the universe the distribution of dark
95:36 matter and even the mysterious force of
95:38 dark
95:42 energy the observable universe is
95:45 estimated by scientists to contain two
95:47 trillion galaxies and yet what we can
95:50 see represents less than 5% of the Earth
95:54 Universe standing over the precipice of
95:57 cosmic understanding we are humbled by
96:00 the scale and complexity of the Universe
96:03 from the smallest particles to the
96:05 largest Galactic filaments each element
96:08 serves as a piece of the
96:11 puzzle here we are a pale blue dot a
96:14 mere Speck in the cosmic web yet it is
96:18 from this vantage point that we've begun
96:20 to unravel the deepest Mysteries of the
96:22 universe armed with telescopes capable
96:25 of looking billions of light years away
96:28 we become not just Spectators but active
96:31 participants in this Cosmic journey and
96:34 each new discovery is a step towards the
96:36 answer to the Eternal question that
96:38 prompts all of us to ponder what other
96:41 Mysteries does the universe hold that we
96:44 have yet to
96:51 unravel imagine a universe it's just
96:54 beginning only a few hundred million
96:57 years old a time when the first galaxies
96:59 were forming thanks to the James web
97:02 Space Telescope we've made
97:03 groundbreaking discoveries that take us
97:05 back to an ancient era before you as a
97:09 universe where every tiny point of light
97:12 is a Galaxy a vast cluster of stars
97:16 planets and
97:19 Mysteries among these countless galaxies
97:21 some are so distant that their light
97:23 took billions of years to reach us
97:26 studying these distant galaxies is of
97:28 great importance because it helps us
97:31 understand the early stages of cosmic
97:33 Evolution and the formation of
97:35 structures in the
97:36 universe this spring astronomers using
97:39 jwst were able to peer into the earliest
97:43 Universe discovering galaxies that
97:45 existed more than 13 billion years
97:49 ago one of these discoveries concerns
97:52 galaxies with red shifts between 9 and
97:55 11 but what does that mean simply put
97:59 red shift is a measure of how much light
98:01 from these galaxies has been stretched
98:03 by the expansion of the universe the
98:06 greater the red shift the farther back
98:08 in time we're looking the light from
98:11 these newly discovered galaxies began
98:13 its Journey when the universe was less
98:14 than a billion years old at that time
98:18 our Milky Way was just beginning to form
98:20 and only the first stars were
98:22 Illuminating the cosmos
98:25 not only are these galaxies incredibly
98:27 distant but they're also incredibly
98:29 young giving us a glimpse into the
98:31 formative ages of the
98:33 universe so how did galaxies like ours
98:36 originate and evolve over billions of
98:39 years let's find
98:42 out in the depths of space hidden among
98:46 countless Stars lies Sears
98:50 43833 this galaxy located at red shift
98:54 8.76 takes us back to a time when the
98:57 universe was less than 600 million years
99:00 old its light traveling through the
99:03 vastness of space brings us valuable
99:06 information about the early stages of
99:08 Galaxy
99:10 formation looking deeper astronomers
99:12 have approached Sears
99:15 16943 an even more distant Galaxy with a
99:17 red shift of
99:19 11.4 this galaxy is one of the oldest
99:22 ever observed emitting its light at a
99:25 time when the universe was only 400
99:27 million years
99:29 old studying such distant galaxies helps
99:32 us understand the processes that led to
99:34 the formation of the first
99:36 Stars finally Max
99:39 0647 djd appears before us observed at
99:44 Red shift
99:46 10.17 this Galaxy's light has taken more
99:49 than 13 billion years to reach
99:51 us it's Discovery was made possible by
99:54 the powerful capabilities of jwst
99:57 revealing its complex structure and
99:59 providing insight into the early
100:03 universe but what is red shift and why
100:06 is it so
100:08 important imagine a car traveling away
100:10 from you just as the car's tail lights
100:13 appear increasingly red as they move
100:15 away from us the light from distant
100:17 galaxies is stretched and shifted toward
100:20 the Red
100:21 Spectrum the higher the red shift the
100:24 more distant and ancient the Galaxy is
100:27 red shift is an essential tool for
100:29 astronomers it allows us to measure the
100:32 distance to these galaxies and therefore
100:34 their
100:35 age light from these galaxies began its
100:38 Journey billions of years ago creating a
100:41 snapshot of the early stages of the
100:44 universe by studying galaxies at
100:46 different red shifts we can piece
100:48 together the story of cosmic
100:51 Evolution open galaxies are not just
100:53 distant objects they are time capsules
100:56 that provide a glimpse into the early
100:59 Universe these discoveries address
101:01 fundamental questions about our
101:04 existence how did the first galaxies
101:07 form what processes drove their
101:09 evolution and what does this tell us
101:11 about our home Milky
101:16 Way the discovery of these distant
101:19 galaxies was made possible by two
101:21 significant observing programs
101:24 these programs used the advanced
101:26 capabilities of the James web Space
101:28 Telescope to look deeper into the
101:30 universe than ever
101:33 before the first program used the
101:35 director's discretionary time to focus
101:37 on observing high red shift
101:40 galaxies under the leadership of
101:42 principal investigator Pablo arabel
101:45 Aro this program aimed to study the
101:48 early Universe searching for Galaxies
101:50 formed just a few hundred million years
101:53 after after the big bang by targeting
101:56 specific regions of the sky DD
101:59 2750 successfully identified several
102:01 ancient galaxies including Sears
102:07 43833 the second program was part of an
102:10 overall observational program led by
102:12 principal investigator Dan
102:15 Co this program was aimed at detailed
102:17 spectroscopic studies of known
102:19 candidates for high red shift galaxies
102:22 the go 1433 program was instrumental in
102:26 confirming the red shifts of these
102:28 galaxies and studying their properties
102:30 in
102:31 detail as part of this program the team
102:34 observed two other objects obtaining
102:36 valuable data on their composition and
102:39 structure jwst used two of its most
102:42 powerful instruments nurc and Nur cam to
102:46 make these groundbreaking observations
102:49 let's take a closer look at how these
102:51 instruments work npec or near infrared
102:55 spectrograph is designed to
102:57 simultaneously obtain Spectra of
102:59 multiple
103:00 galaxies this instrument can analyze
103:03 light from galaxies to determine their
103:05 chemical composition temperature density
103:08 and red
103:09 shift this instrument is crucial for
103:12 studying the detailed properties of
103:14 galaxies and understanding their
103:16 evolution over time nurc operates in the
103:19 near infrared which is ideal for
103:21 observing distant galaxies
103:24 by dividing the incoming light into its
103:27 constituent wavelengths the instrument
103:29 creates a detailed fingerprint of each
103:31 Galaxy revealing its unique
103:35 characteristics Nur cam or near infrared
103:38 camera serves a different but
103:40 complimentary
103:41 purpose it takes high resolution images
103:44 of galaxies allowing astronomers to
103:46 study their morphology and structure the
103:50 camera is particularly effective at
103:52 observing faint in distant objects
103:55 making it indispensable for identifying
103:57 and analyzing high red shift
104:00 galaxies the Nur Cam's wide field of
104:02 view allows large areas of the sky to be
104:05 captured in a single image this
104:08 capability is critical for surveys such
104:10 as DD
104:11 2750 and go
104:13 1433 where astronomers need to observe
104:16 many galaxies
104:18 simultaneously by combining detailed
104:20 Spectra with highresolution images
104:23 scientists can build a complete picture
104:25 of these ancient
104:30 galaxies so what exactly did the
104:32 scientists see these ancient galaxies
104:36 are incredibly small compared to our
104:38 Milky Way they are less than a kilop
104:41 parac
104:43 across by comparison that's about a
104:45 thousand times smaller than our Milky
104:48 Way despite their diminutive size
104:51 they're bustling with activ activ ity
104:53 typical of the young star forming
104:55 galaxies of the early Universe some of
104:58 them even exhibit complex structures
105:00 affected by gravitational lensing a
105:02 phenomenon in which a massive foreground
105:04 object distorts the light from a
105:06 background object allowing us to see
105:09 them in Greater detail than would
105:11 otherwise be
105:12 possible but why do these size
105:15 differences matter it's the small size
105:17 of these galaxies that suggests they're
105:20 in the early stages of their evolution
105:23 in the young universe galaxies were
105:25 still forming and merging leading to
105:28 intense periods of star formation these
105:31 compact galaxies are like snapshots of
105:33 the early Universe showing us how
105:35 galaxies start their lives and grow over
105:40 time what do these galaxies look like
105:43 Sears
105:44 43833 for example looks like a bright
105:47 compact object with hints of structure
105:49 indicating regions of intense star
105:51 formation
105:53 Sears 16943 although smaller also shows
105:57 signs of active star
105:59 formation in contrast Max
106:02 0647 djd shows a more complex morphology
106:06 due to lensing effects and shows
106:08 multiple images of the same
106:11 galaxy however it's the understanding
106:14 the light of these galaxies that's key
106:16 to unlocking their
106:18 secrets this is where spectral energy
106:21 distribution or said comes into play the
106:24 set represents the range of energy
106:26 emitted by a Galaxy in different
106:28 wavelength ranges from ultrav Violet to
106:32 infrared by studying the set astronomers
106:35 can infer various physical properties of
106:37 a galaxy such as its age mass and star
106:41 formation
106:43 rate we use the Nur speec and Nur cam
106:47 data on jwst to create the
106:50 said after that we can model it using
106:53 software that simulates different galaxy
106:55 formation and evolution
106:57 scenarios by fitting The observed data
106:59 to these models we can estimate the
107:02 Galaxy's Stellar mass star formation
107:05 history and other important
107:07 parameters the sets of these galaxies
107:10 indicate a relatively young Stellar
107:12 population with intense star formation
107:15 occurring less than 100 million years
107:18 ago a detailed analysis of these sets
107:20 helps us piece together the life history
107:22 of these ancient
107:27 galaxies as we've already mentioned the
107:30 light from these distant galaxies
107:32 contains a wealth of information
107:34 especially in the form of emission
107:36 lines emission lines are bright lines
107:39 appearing at specific wavelengths in the
107:42 spectrum that occur when elements in the
107:44 galactic gas become energized and emit
107:47 light each element produces a unique set
107:50 of lines much like a fingerprint which
107:53 allows us to determine the chemical
107:55 composition of the
107:57 Galaxy in addition to identifying
107:59 elements emission lines also reveal the
108:02 physical properties of the Galaxy's gas
108:04 and Stars by analyzing the intensity and
108:07 ratio of these lines astronomers can
108:10 estimate the rate of star formation
108:12 showing how many new stars are being
108:14 born in the
108:15 Galaxy for example a strong Hal Alpha
108:18 emission line indicates a high star
108:20 formation rate in indicating that the
108:23 Galaxy is actively producing new
108:27 stars the emission lines also help
108:29 determine the oxygen content of the
108:31 Galaxy which is an indirect indicator of
108:33 its overall
108:35 metallicity this tells us how many
108:37 generations of stars have existed
108:40 enriching the Galaxy with heavier
108:41 elements over
108:43 time understanding these properties
108:45 helps to compile the history of the
108:47 Galaxy and determine the stage of its
108:51 Evolution one one of the most intriguing
108:53 features observed in these distant
108:55 galaxies is dampit Lyman alpha or D but
108:59 what exactly is a
109:01 d simply put the D is a broad absorption
109:06 line in the spectrum of a galaxy caused
109:08 by the presence of large amounts of
109:10 neutral hydrogen
109:12 gas this absorption line is much broader
109:16 than normal lines indicating a
109:18 significant amount of
109:20 gas dlas are important because they
109:23 allow us to directly measure the amount
109:25 of neutral hydrogen in the early
109:28 Universe this information helps us
109:30 understand how galaxies acquire the gas
109:32 that fuels star formation and how they
109:36 evolve by studying the D we can learn
109:39 about the conditions in the universe
109:41 when these galaxies
109:42 formed the detection of D in these
109:45 galaxies involves analyzing their
109:47 Spectra for characteristic broad
109:49 absorption
109:50 features this process allows ows us to
109:53 quantify the amount of gas present and
109:56 understand the environment around young
109:59 galaxies the presence of D in these
110:01 galaxies tells us that they're rich in
110:03 neutral hydrogen which is crucial for
110:06 Star formation it also provides insight
110:09 into the intergalactic medium the space
110:11 between galaxies and its role in Galaxy
110:15 formation by comparing da features to
110:18 different galaxies we can build a more
110:19 complete picture of the early universe
110:26 the discovery of these ancient galaxies
110:28 provides a unique opportunity to compare
110:31 them to other known super luminous
110:34 galaxies unlike their more evolved
110:36 counterparts these newly discovered
110:38 Galaxies have distinctive
110:40 characteristics that set them apart from
110:43 others what makes these new discoveries
110:45 special is the unusual amount of dense
110:48 gas surrounding them this gas consisting
110:51 mainly of hydrogen and helium is one of
110:54 the earliest elements to exist in the
110:57 universe the presence of such dense gas
110:59 is unusual because it indicates that
111:02 these galaxies are in the earliest
111:04 stages of their
111:05 evolution this dense gas is likely to
111:08 fuel the formation of new Stars playing
111:11 a crucial role in their
111:14 evolution another unique feature of
111:16 these galaxies is their low metallicity
111:19 in astronomy metallicity refers to the
111:21 content of elements heavier than
111:23 hydrogen and helium in a
111:26 galaxy low metallicity also confirms
111:29 that these Galaxies have not gone
111:30 through many Star formation Cycles which
111:33 means that they have fewer heavy
111:34 elements and that they're in the
111:36 earliest stages of their
111:38 evolution thus they're an ideal
111:40 laboratory to study the initial stages
111:42 of Galaxy formation and their
111:45 evolution this information will help us
111:47 piece together the sequence of events
111:49 that led to the formation of galaxies in
111:51 the early universe
111:55 these discoveries also fit into the
111:57 broader context of understanding the
111:59 history of the universe During the
112:02 period known as the age of
112:03 reionization the universe went from opeg
112:06 to
112:07 transparent the galaxies discovered by
112:10 jwst are among the first to contribute
112:12 to the reionization process by ionizing
112:15 the gas around
112:17 them the next steps will involve
112:19 creating large statistical samples of gy
112:22 galaxies to estimate in detail the
112:24 prevalence and brightness of their
112:26 features researchers will continue to
112:28 study where the gas is how much of it is
112:31 near the center of galaxies and whether
112:32 it's primordial or already contains
112:35 heavier
112:36 elements in the meantime we'll await new
112:39 results and discoveries which we will be
112:41 sure to report to
112:48 you in the shadowy depths of our solar
112:51 system far beyond the last known gas
112:53 giant lies a world shrouded in intrigue
112:57 and mystery this is Pluto once consider
113:00 the ninth planet it now occupies a
113:03 separate category at the center of heat
113:05 debate and scientific curiosity for
113:08 decades Pluto remained a blurry Speck of
113:11 light in our most powerful telescopes a
113:14 distant dot at the edge of our vision it
113:17 was a world waiting to be discovered
113:19 keeping its secrets in the cold dark
113:21 depths of
113:23 space at the dawn of the 21st century an
113:27 unprecedentedly ambitious Mission began
113:30 the New Horizon spacecraft embarked on a
113:32 billion mile journey to explore Pluto's
113:35 icy Frontiers what it discovered was
113:38 astonishing in its diversity towering
113:41 ice mountains huge nitrogen glaciers and
113:44 the legendary heart-shaped Tom B Regio
113:47 an object so large it can be seen from
113:50 space but these discoveries are just the
113:52 beginning join us as we journey together
113:55 into the icy depths of the outer solar
113:58 system where one dwarf planet is eagerly
114:00 waiting to tell us its
114:12 story in the early 20th century the
114:15 search for ninth planet the mysterious
114:17 Planet X gripped the world of astronomy
114:20 the search was not just about adding
114:21 another name to the list of planets it
114:24 was about understanding the Unseen
114:25 forces that shaped the orbits of the
114:28 then already known celestial bodies
114:30 around us at the center of the search
114:32 was LEL observatory in Flagstaff Arizona
114:35 where a young astronomer named Clyde
114:37 tomow embarked on a painstaking journey
114:40 through space armed with a telescope and
114:43 photographic plates tombow set out to
114:46 scrutinized the night sky inch by inch
114:49 in search of an elusive planet that
114:51 eluded
114:52 protection on a February night in 1930
114:56 Tom Ba's diligence paid off among the
114:59 countless Stars he spotted a moving
115:02 object a tiny Speck of light that was
115:05 unlike anything else he had observed it
115:07 was Pluto a distant world named after
115:10 the Roman god of the underworld a
115:13 discovery that would change the
115:14 boundaries of our solar system as the
115:17 decades passed Hubble Space Telescope
115:19 brought us closer to Pluto than ever
115:21 before launched into orbit in 1990
115:24 Hubble's powerful lens pierced the veil
115:27 of distance separating us from the outer
115:29 solar system the first images of Pluto
115:31 were a revelation transforming the
115:33 distant dwarf planet from a mere glowing
115:36 dot to a world with distinct features
115:40 these Hubble images provided the basis
115:42 for a more detailed study they showed
115:44 Pluto's complex surface marked by
115:46 variations in brightness and color
115:49 hinting at a dynamic World waiting to be
115:51 explored
115:53 an odyssey of discovery that began with
115:55 a single blinking dot on a photographic
115:57 plate has brought us to the threshold of
115:59 a new frontier Pluto once a mere
116:02 curiosity at the edge of our solar
116:04 system was about to reveal its Secrets
116:07 through a Relentless pursuit of
116:09 knowledge and a Relentless Spirit of
116:13 exploration 5 4 3 2
116:19 1 we have ignition and lift off but
116:22 NASA's new horizon space trck on a
116:25 decade voage to visit the Pluto and then
116:28 Beyond in January 2006 Humanity embarked
116:32 on another of its most ambitious
116:34 Journeys New Horizons a spacecraft no
116:37 bigger than a grand piano was poised
116:40 across the vast emptiness of space
116:42 heading for a world barely seen by human
116:45 eyes its mission is to unlock the
116:47 secrets of Pluto a mysterious dwarf
116:50 planet at the edge of our solar system
116:52 system when New Horizon soared into the
116:55 sky it carried the aspirations of
116:57 countless people who had devoted years
116:59 to that moment the journey was a
117:02 marathon of cosmic proportions spanning
117:04 nearly a decade and More Than 3 billion
117:07 miles with Precision it plotted a path
117:11 through the void Guided by the
117:13 gravitational slingshots of celestial
117:15 bodies in its
117:17 path in 2015 after nine long years as
117:21 new Horizons approached its distant
117:23 destination the whole world watched with
117:26 baited breath the first images were
117:29 simply revolutionary Pluto which was
117:32 once just a speck of light even in the
117:34 most powerful telescopes now appeared to
117:36 be a world of mountains valleys and
117:40 plains the landscape that came into view
117:43 was strikingly varied ice mountains some
117:46 as tall as the Rockies Rose proudly to
117:48 the surface their peaks shrouded in a
117:51 blanket of methane
117:53 snow spot neck Pia a nitrogen ice plane
117:57 stretched across the entire dwarf planet
117:59 its surface modeled with a complex
118:01 pattern of ridges and
118:03 depressions among the most striking
118:06 discoveries are signs of geological
118:08 activity Pluto long thought to be a
118:10 frozen Relic from the dawn of the solar
118:12 system turned out to be alive glaciers
118:16 of nitrogen ice slowly flowed across the
118:19 landscape and hints of cryo volcano
118:22 indicated that this distant world was
118:25 not as inactive as previously
118:28 thought New Horizons leap into the
118:31 unknown bridge the gap between
118:32 assumptions and reality Pluto was no
118:35 longer just a point of light in our
118:36 telescopes it was a dynamic world full
118:40 of surprises and Beauty waiting at the
118:42 edge of our solar system it was just the
118:44 beginning of a new chapter in our
118:47 understanding of the
118:50 cosmos Pluto's expand of rugged
118:52 Landscapes is home to one of its most
118:55 mesmerizing features the spotnik plantia
118:58 this enormous heart-shaped Glacier is
119:00 not just a striking visual Landmark it's
119:03 a geological Marvel that's changed the
119:06 way we think about this distant world
119:08 the origin of spotnik Mia is a story of
119:11 cosmic forces this vast Basin stretching
119:15 more than 650 Mi is believed to have
119:18 been formed by the impact of a massive
119:20 Celestial body and that changed Pluto's
119:23 surface and possibly its entire geology
119:26 the Basin was filled with various ices
119:29 mostly nitrogen creating a smooth
119:31 reflective plane that contrasts sharply
119:34 with the surrounding
119:35 topography the surface of spotnik plania
119:38 is modeled with a complex pattern of
119:40 convection cells each the size of a
119:43 country on Earth these cells are the
119:46 surface manifestation of ice in slow
119:48 motion turning and flowing in response
119:51 to the weak Heat coming from Pluto's
119:53 interior this lava lamp-like process
119:56 shows that Pluto is far from the inert
119:58 Frozen world we once imagined more
120:02 Mysteries lie beneath the icy facade of
120:05 spotnik plena the uniform Mass
120:08 distribution in this region obtained
120:10 from spacecraft measurements hints at
120:12 the presence of a denser layer beneath
120:14 the ice scientists speculate that this
120:16 may be a subsurface ocean it's possible
120:19 that this Reservoir could contain liquid
120:22 water isolated by the ice crust
120:26 above among other discoveries scientists
120:29 have also found that Pluto has an
120:31 atmosphere hovering above its icy
120:33 surface as thin and fragile as an
120:35 atmosphere can be on the cold fringes of
120:37 the solar system composed mostly of
120:40 nitrogen with traces of methane and
120:42 carbon monoxide this thin veil provides
120:45 Clues to understanding the planet's most
120:47 mysterious processes the structure of
120:50 the planet's atmosphere does not matter
120:52 the primary expectations when New
120:54 Horizons flew by it found an atmosphere
120:56 extending hundreds of miles above the
120:59 surface much more extensive than
121:01 expected this thin atmospheric layer is
121:04 stratified and has a complex interplay
121:06 of gases that scatter and refract
121:08 sunlight creating a mesmerizing blue hue
121:11 that resembles Earth's Own
121:14 Sky because Pluto's Journey around the
121:16 Sun is unlike any other planet in our
121:18 solar system with an orbital period of
121:21 an unimagined inable 248 Earth years
121:24 each season on Pluto can last decades
121:28 its trajectory is markedly elliptical it
121:31 is much closer to the Sun at Pelion than
121:33 at aelian and its axis is tilted at an
121:36 angle of
121:37 120° resulting in extreme seasonal
121:40 variations on its surface as Pluto
121:43 approaches its parhelion the heat from
121:45 the distant Sun though faint is enough
121:48 to cause a remarkable
121:50 transformation surface es composed of
121:53 nitrogen methane and carbon monoxide
121:55 begin to sublimate a process by which
121:58 these ice change from a solid state to a
122:00 gaseous State without changing to an
122:03 intermediate liquid state this
122:05 sublimation is most pronounced in
122:07 regions exposed to the sun's weak but
122:10 constant Rays resulting in an increase
122:12 in atmospheric pressure as gases
122:15 previously trapped in ice form are
122:17 released to the outside this outgassing
122:21 thickens Pluto atmosphere making it more
122:23 substantial during these warm periods
122:26 the atmosphere expands Rising hundreds
122:29 of kilometers above the surface much
122:31 more than during colder periods this
122:34 expansion is uneven and it's influenced
122:36 by Pluto's topography and the
122:38 composition of its ice creating a
122:40 complex and dynamic atmospheric system
122:44 as Pluto continues its long journey
122:46 moving away from the Sun and toward more
122:48 distant parts of its orbit the
122:50 atmosphere is undergoing a a dramatic
122:52 turn of events the gases that once
122:55 thickened the atmosphere are now Cooling
122:57 and condensing falling back to the
122:59 surface is a fine snow of nitrogen
123:02 methane and carbon monoxide this
123:05 cyclical process of sublimation and
123:07 condensation is a defining feature of
123:10 Pluto's climate changing its surface
123:12 over the centuries the dance of ice and
123:15 Vapor unfolding over the course of
123:17 Pluto's long year paints a portrait of a
123:19 world in constant motion far from a
123:22 static Frozen Wasteland pluto surface is
123:25 a dynamic environment a reminder of the
123:28 active and everchanging nature of even
123:30 the most distant members of our solar
123:33 system another exciting discovery about
123:35 Pluto's atmosphere is its Escape rate
123:38 unlike the strong magnetic fields and
123:41 gravitational pole that protect the
123:43 atmosphere of the larger planets Pluto's
123:45 weak gravity allows much of its
123:47 atmosphere to escape into space this
123:50 atmospheric Cape contributes to the
123:53 ionized gas tail an invisible comet-like
123:56 trail that Pluto leaves behind it as it
123:58 orbits the sun this leakage is not a
124:01 steady gentle flow but a complex
124:03 interaction with a solar wind a stream
124:06 of charged particles emanating from the
124:08 Sun these particles colliding with
124:11 escaping atmospheric gases create a
124:14 dynamic and everchanging environment
124:16 around Pluto a miniature magnetosphere
124:19 in which the drama of solar and pl
124:21 planetary forces is played
124:25 out from Pluto's Dynamic atmosphere and
124:28 unique climate we move to its largest
124:31 moon Chon and discover relationships and
124:33 Landscapes that change the very
124:35 definition of celestial bodies in the
124:37 outer part of our solar system Sharon
124:40 Pluto's largest satellite orbits and
124:43 synchronized motion with it discovered
124:45 in 1978 this Celestial body turns out to
124:48 be more than just a satellite it's it is
124:50 a whole world World filled with
124:53 geological wonders and a unique history
124:55 that's intertwined with that of
124:58 Pluto as New Horizons flew past cheron
125:01 they saw Escape of canyons so deep and
125:04 wide they could easily swallow up parts
125:07 of Earth's Grand Canyon these chasms
125:10 stretched across the surface of the
125:12 satellite telling a story of geologic
125:14 upheaval mountains Rising dramatically
125:17 against the lunar surface reveal a
125:19 dynamic history their people
125:22 casting Long Shadows over The Valleys
125:24 below the origins of Chon's dramatic
125:27 topography lie in its past marked by
125:30 internal processes and possibly
125:32 cryovolcanic activity as Chon cooled and
125:36 compressed over millions of years its
125:38 crossed split resulting in vast Canyons
125:42 at the same time mountains may have
125:43 formed from tectonic activity as the
125:45 moon's surface flexed and broke pushing
125:48 some areas upward and raising Peaks
125:53 the interaction between Pluto and Chon
125:55 is a kind of gravitational ballet in
125:58 which both bodies are locked in a
125:59 synchronized orbit this means that Chon
126:02 always faces Pluto on the same side and
126:05 vice versa a phenomenon known as tidal
126:07 locking unlike most moons which orbit
126:10 around their planets Pluto and cheron
126:13 orbit around a point in the space
126:15 between them known as the Berry Center
126:17 this unique Arrangement challenges the
126:19 conventional definitions of planets
126:21 moons suggesting a binary system where
126:24 both bodies are Partners in their
126:25 Celestial
126:27 tandem this gravitational partnership
126:30 extends Beyond Pluto and Chon affecting
126:32 the orbits of Pluto's smaller moons
126:34 sticks nicks garos and Hydra Chon's
126:39 presence stabilizes these smaller
126:41 satellites maintaining the complex
126:43 balance of the system the Dynamics of
126:46 this Min solar system give us valuable
126:48 insight into the gravitational
126:50 interactions that shape the orbits of
126:52 celestial bodies throughout the
126:57 Universe located in the vast Realm of
126:59 the Kyper Bel Pluto stands like a
127:02 sentinel at the edge of our solar system
127:05 this region a vast cluster of icy bodies
127:08 extending beyond the orbit of Neptune is
127:10 a relic of the early solar system and
127:13 holds the keys to understanding the
127:15 formation and evolution of our Cosmic
127:17 neighbor Pluto once thought to be the
127:20 ninth planet has found a its relatives
127:22 among the vast number of Kyper belt
127:24 objects or
127:25 kbos like dwarf planets like
127:28 haia and Macky macki to smaller lesser
127:31 known bodies each kbo has its own story
127:35 that contributes to the picture of the
127:36 solar system Pluto's varied landscape
127:39 from nitrogen ice Plaines to towering
127:42 mountains and dynamic atmospheres
127:45 reflect the complexity and diversity of
127:47 the Kyper belt landscape the Kyper belt
127:50 is a window to the Past a frozen Archive
127:54 of the birth of the solar system the
127:57 objects included in it including Pluto
127:59 are remnants of the time of planetary
128:01 formation Untouched by the sun's Heat
128:04 their composition ice mixed with rocks
128:07 gives an idea of the materials that
128:09 abounded in the early solar system and
128:11 allows us to understand the processes
128:13 that led to the birth of the planets
128:16 exploring Pluto and its neighbors in the
128:18 Kyper belt has far-reaching implications
128:20 for our understanding of the solar
128:22 system each Mission like the New
128:24 Horizons flyby of Pluto and aroth peels
128:27 away layers of mystery revealing the
128:31 conditions and processes that prevailed
128:33 in the outer solar system billions of
128:35 years ago forcing us to consider the
128:37 Dynamics of planetary formation and the
128:40 boundaries between planets and smaller
128:42 celestial bodies Pluto's position of the
128:45 Kyper belt emphasizes the
128:47 interconnectedness of celestial bodies
128:50 from the smallest piece of ice to the
128:52 largest gas giant the Dynamics of the
128:55 Kyper belt with its resonances and
128:58 orbital interactions influen the
129:00 stability and evolution of the outer
129:02 solar system shaping the trajectories of
129:05 comets and affecting the environment of
129:10 Neptune however New Horizons exploration
129:13 didn't end there after its historic
129:15 flyby of Pluto it traveled onward to
129:18 aroth a Kyper belt object meeting it on
129:21 January 1st 2019 marking the next
129:24 milestone in space
129:26 exploration oraco resembling a clay
129:29 snowman demonstrated the soft merger of
129:31 two primordial objects offering
129:34 unprecedented insight into the building
129:36 blocks of the early solar system the
129:39 story of arico's formation is a
129:41 testament to the slow and gentle
129:43 processes that dominated the outer
129:45 regions of the early solar system the
129:48 large lobe called wenu is not a single
129:51 form
129:51 but a cluster of a dozen rocks each more
129:54 than 3 m wide huddled around a central
129:57 slab this cluster refutes previous
129:59 Notions of high velocity collisions in
130:01 planetary formation suggesting instead a
130:04 gradual merger at speeds of less than a
130:07 dozen ft per
130:09 second this intricate interaction
130:12 between two loes losing angular momentum
130:15 and smoothly merging forms an image of a
130:18 patient Cosmos where the building blocks
130:20 of the pl planets come together in a
130:23 Heavenly cycle of gravity and
130:26 time looking ahead The Horizon of solar
130:29 system exploration is littered with
130:31 potential concepts for the next New
130:33 Horizon's missions are already stirring
130:35 the imagination of scientists and
130:37 Engineers one of them envisions an
130:39 Orbiter capable of mapping Pluto's
130:41 surface with unprecedented resolution
130:43 penetrating the mysteries of its small
130:45 satellites and even exploring the
130:48 Eternal darkness of the regions
130:50 enveloped by Pluto's axial
130:52 tilt the project inspired by the legacy
130:55 of Cassini proposes to use Chon's
130:57 gravity to create complex orbital
131:00 trajectories around Pluto allowing for a
131:03 comprehensive study of the dwarf planet
131:05 and its satellites such missions could
131:07 utilize electric propulsion replicating
131:10 the success of NASA's Dawn and could
131:13 potentially go beyond the Pluto system
131:15 and explore New Frontiers in the Kyper
131:18 belt new technologies such as direct
131:20 Fusion drives promised to propel future
131:23 spacecraft to the outer solar system
131:25 with unprecedented speed and
131:28 efficiency a report titled the fusion

131:45 kilogram Orbiter and Landing module
131:47 could reach Pluto in Just 4 years more
131:50 than twice the speed of New Horizons
131:52 these promising propulsion systems could
131:55 significantly shorten the travel time
131:57 opening new pages in The exploration of
131:59 the Distant Worlds of our
132:03 outskirts as we travel the vastness of
132:06 space exploring Distant Worlds and
132:09 discovering the secrets they hold our
132:11 understanding of the cosmos continues to
132:13 evolve the story of Pluto from its
132:16 Discovery to the present day is a vivid
132:18 reminder of the dynamic nature of
132:20 science and our attempts to categorize
132:23 the universe around us Pluto's unique
132:26 orbital interaction with Neptune adds
132:29 another layer to its fascinating story
132:31 during its 248e orbit around the Sun
132:35 Pluto appears closer to the Sun than
132:37 Neptune for a brief time challenging the
132:40 view of its position as the ninth planet
132:43 this Crossing of orbits when Pluto and
132:45 Neptune change places occurs because of
132:48 the elliptical trajectory of Pluto's
132:50 orbit and its inclination relative to
132:52 the plane of the solar system despite
132:54 this temporal shift Pluto's overall
132:57 trajectory ensures that there's no risk
132:59 of collision with Neptune due to their
133:01 Mutual orbital
133:03 resonance the rather lengthy debate over
133:06 Pluto's planetary status has long
133:08 sparked discussion and controversy that
133:10 reaches far beyond the astronomical
133:12 community in 2006 the international
133:15 astronomical Union revised the
133:17 definition of planet in our solar system
133:20 which led to Pluto's reclassification as
133:22 a dwarf planet this moment was not only
133:25 a turning point for Pluto but also a
133:27 catalyst for the reclassification of
133:29 celestial bodies Pluto's history is
133:32 closely tied to the Kyper belt a region
133:34 teeming with objects that blur the
133:36 boundaries between planets moons and
133:39 smaller celestial bodies studying Pluto
133:42 and its neighbors makes us think about
133:43 the wide range of characteristics that
133:45 celestial bodies can possess from their
133:48 atmospheres and geology to their orbit
133:51 and
133:52 interactions in the grand canvas of the
133:54 cosmos every thread from the smallest
133:57 asteroid to the mightiest gas giant
134:00 plays a critical role in the history of
134:02 our solar system as we stand at the
134:05 threshold of new exploration Pluto's
134:07 Legacy and the knowledge gained from the
134:10 Kyper belt serve as beacons guiding us
134:12 to a deeper understanding of our place
134:15 in the
134:16 universe rethinking our Cosmic
134:18 neighborhood is not just about the
134:20 labels we place it but about embracing
134:22 the diversity and complexity of the
134:30 universe surely you've heard by now that
134:32 black holes can be so massive that they
134:35 can outshine entire
134:37 galaxies but some of them are quite
134:39 mobile so much so that they roam the
134:42 Milky Way like Cosmic ghosts
134:46 undetectable of course you may be
134:48 confused or even mesmerized by the fact
134:50 that the nearest black hole to Earth is
134:53 not as far away as you think and when
134:55 these Cosmic Giants Collide they
134:58 generate frequencies as unique as
135:00 fingerprints frequencies that may hold
135:02 the key to unlocking the deepest
135:05 Mysteries of the
135:06 universe but did you know that these
135:08 waves interact in a far more complex way
135:11 than we ever
135:13 imagined get ready for an extraordinary
135:16 Journey as we begin to delve into the
135:18 mysteries of black holes the truly
135:21 enigmatic Titans of the
135:35 universe in the cosmic pattern black
135:37 holes are Weavers of riddles and
135:40 paradoxes although we're familiar with
135:42 small black holes the remnants of dying
135:45 stars and super massive ones lurking in
135:48 the hearts of galaxies there isn't
135:51 enigmatic class that eludes our
135:53 telescopic gaze intermediate Mass black
135:59 holes the Hubble Space Telescope our Eye
136:03 in the Sky recently focused its
136:06 attention on mess
136:08 4 the ball cluster closest to
136:11 Earth what he discovered was nothing
136:14 short of
136:15 groundbreaking a black hole with a mass
136:18 about 800 times the mass of our sun
136:22 this celestial object is somewhere
136:24 between 6,000 and 7,200 light years away
136:28 from us why is this so important you ask
136:31 well for years astronomers have
136:33 struggled with a gap in the black hole
136:35 genealogical tree we've had evidence of
136:39 both small black holes a few times the
136:41 mass of our sun and super massive black
136:44 holes with masses in the millions or
136:47 billions of solar masses but black Hol
136:51 of intermediate Mass turned out to be a
136:53 missing link mysterious relatives about
136:56 which everyone has heard but no one has
137:00 met an equally interesting question is
137:03 how these black holes of intermediate
137:04 Mass form one Theory suggests that they
137:08 could be the nuclei of dwarf galaxies
137:11 that lost their outer stars when they
137:13 merged into larger galaxies another
137:16 theory states that they could have
137:17 formed from the collision and merger of
137:19 smaller black holes
137:22 identifying these elusive black holes is
137:24 no easy task it requires a symphony of
137:27 scientific instruments from x-ray
137:29 observatories to precise calculations
137:32 based on the motion of surrounding
137:34 Stars the huble Space Telescope with its
137:37 unprecedented resolution has played an
137:40 important role in this discovery the
137:43 presence of a black hole affects its
137:44 Cosmic environment by studying the
137:47 gravitational choreography of stars
137:49 orbiting this massive object scientists
137:51 have been able to estimate its mass it's
137:54 like understanding the character of an
137:56 invisible Puppeteer by watching the
137:57 puppets dance the discovery of
138:00 intermediate Mass black holes could
138:02 rewrite the cosmic narrative they may be
138:05 key players in the formation of galaxies
138:08 and may even hold Clues to the
138:09 mysterious dark matter that makes up
138:11 most of the
138:15 universe in a cosmic world where
138:17 distances are often
138:19 incomprehensible the term neighbor takes
138:21 on new meaning while our closest
138:24 Celestial neighbor the Moon is only
138:28 238,857
138:47 the European Southern Observatory ESO
138:50 made headlines when it announced the
138:52 discovery of a black hole in the HR 6819
138:56 system located just 1, light years
139:00 away this would make it the closest
139:02 known black hole to Earth however this
139:05 claim was later disproved subsequent
139:08 research by Abigail Frost of the
139:10 University of louen in Belgium found
139:12 that HR 6819 does not contain a black
139:15 hole at all instead it's a double star
139:18 system in which one star absorbs the
139:21 mass of the other a process known as
139:23 Stellar
139:25 vampirism this Revelation was more than
139:27 just a correction it opened up new
139:29 possibilities for studying Stellar
139:31 Evolution and
139:33 interactions after the ejection of HR
139:36 6819 the title of the closest black hole
139:39 to Earth went to Gaia
139:41 bh1 this black hole was discovered by
139:44 the Gaia space Observatory a mission of
139:46 the European Space Agency Esa the main
139:49 task of guy is to map the Milky Way in
139:52 unprecedented detail and it was thanks
139:55 to this painstaking work that Gia bh1
139:58 was discovered as the closest known
140:01 black hole to Earth Gaia bh1 offers a
140:03 unique opportunity for scientific
140:05 observations and research its relative
140:08 proximity allows for more detailed
140:10 measurements and may help answer
140:12 fundamental questions about the
140:14 properties of black holes such as mass
140:16 rotation and behavior near their event
140:19 Horizons
140:21 study of black holes like guia bh1
140:23 relies on several observational
140:26 instruments from x-ray observatories to
140:29 radio
140:30 telescopes each instrument represents a
140:32 piece of the puzzle the closer a black
140:35 hole is the more accurately these
140:37 instruments will be able to measure its
140:39 properties offering a more complete
140:41 picture of these mysterious
140:44 objects Beyond its scientific
140:46 significance the idea of a nearby black
140:49 hole captivate the public imagination it
140:52 makes the cosmic more personal and
140:55 provides a tangible Focus for education
140:57 and Outreach the story of Gaia bh1 can
141:00 serve as a Gateway for people to
141:02 astronomy and astrophysics enriching our
141:05 Collective understanding of the
141:09 universe in the cosmic theater black
141:12 holes often play the role of mysterious
141:15 villains lurking in the centers of
141:17 galaxies or double star systems
141:20 but what happens when a black hole is
141:22 left to roam the universe alone
141:24 unconnected to any Galaxy or Star what
141:27 causes these black holes to become
141:29 rogued and how do astronomers even
141:32 manage to find such elusive objects
141:35 let's dive into the Mysterious World of
141:37 Rogue black
141:40 holes the scientific Community was
141:43 ecstatic when astronomers announced the
141:44 first ever unambiguous discovery of a
141:47 Wandering black
141:48 hole located 5,000 Lighty years away
141:51 from Earth this black hole weighs 7.1
141:55 times the mass of our sun and moves at a
141:58 staggering speed of about 28 m per
142:01 second the key to this revolutionary
142:04 Discovery lies in a phenomena predicted
142:06 by Einstein's general theory of
142:07 relativity known as gravitational
142:11 lensing when a massive object such as a
142:13 black hole passes in front of a
142:15 background star its intense
142:18 gravitational field deflects the the
142:20 light of that star this creates a brief
142:23 brightening phenomena which is how this
142:25 wandering black hole was
142:28 discovered as we know the birth of a
142:30 Wandering black hole is nothing short of
142:32 a dramatic event when a massive star
142:35 exhausts its nuclear fuel its core
142:38 collapses leading to a supernova
142:42 explosion the energy released can be so
142:44 enormous that it ejects the newborn
142:47 black hole from its Stellar cradle
142:49 sending it on an endless journey through
142:52 space and this is how our newly
142:54 discovered wandering black hole likely
142:57 began its Cosmic
142:58 Odyssey what is even more intriguing is
143:01 the speed at which this wandering black
143:03 hole is traveling its speed is about 28
143:06 m/ second which is a very large value
143:09 relative to the nearest Stars this speed
143:12 is likely the result of the very impact
143:15 of a Dying massive star sending it on a
143:18 lonely
143:19 Journey the discovery of this lone black
143:21 hole is just the tip of the iceberg in
143:25 upcoming missions such as the European
143:27 space agency's Gaia telescope and NASA's
143:30 nacy Grace Roman Space Telescope
143:32 astronomers expect to find even more
143:34 such space
143:36 Travelers these future discoveries will
143:39 not only increase the number of known
143:41 Rogue black holes but also refine our
143:44 theories about their properties and
143:48 frequencies each gal gxy is like a
143:51 cosmic dance floor where Stars gas and
143:54 dust swirl in a complex choreography at
143:58 the center of this dance is a super
144:00 massive black hole that sets the Rhythm
144:02 and Temple of the entire galaxy research
144:05 published in the monthly notices of the
144:07 Royal Astronomical Society shows that
144:10 galaxies and their Central black holes
144:12 grow together regardless of their
144:14 location in the
144:15 universe astronomers have long been
144:18 puzzled over the relationship between
144:19 the mass of a galaxy and its Central
144:22 black hole the two seem to be aware of
144:24 each other even though the black hole is
144:26 much smaller than the Galaxy in which it
144:29 resides this relationship implies a deep
144:32 Cosmic connection a kind of cosmic
144:35 codependency where the growth of one
144:37 affects the other one of the most
144:40 intriguing questions in astronomy is
144:42 which came first the Galaxy or its
144:46 Central the answer remains
144:48 elusive what is clear however is that a
144:51 close connection was established very
144:53 quickly on a cosmic scale Paving the way
144:55 for a complex interplay of growth and
144:58 evolution let's dive into the young
145:01 gas-rich galaxies the Cradle of giant
145:05 black holes these galaxies are like
145:07 Cosmic nurseries teeming with the raw
145:10 materials needed for Star formation and
145:12 black hole growth studies show that such
145:15 galaxies known as blue nuggets have
145:17 exceptionally High star formation rates
145:20 they are fed by nearby gas streams which
145:23 not only accelerate star formation but
145:25 also contribute to the rapid growth of
145:27 their Central black holes when black
145:30 holes are fed they become active the gas
145:33 around them heats up and emits powerful
145:36 waves of radiation this heated gas is
145:39 less likely to hit the black hole
145:41 creating a feedback loop that stabilizes
145:44 the size of the black hole however as
145:47 the Galaxy grows it can push more gas
145:49 towards the center allowing the black
145:52 hole to feed and Grow
145:54 Again the relationship between galaxies
145:57 and their black holes adjusts itself if
146:00 a black hole is too large for its Galaxy
146:03 it grows slower and if it's too small it
146:06 catches up due to the abundance of gas
146:08 and dust in the
146:09 Galaxy so some galaxies defy the norm
146:13 these blue nuggets despite their small
146:16 size have exceptionally large Central
146:19 black holes
146:21 as these galaxies age their star
146:23 formation stops and they turn into red
146:26 nuggets still retaining their huge black
146:30 holes as we move farther into the black
146:32 hole Abyss it becomes apparent that
146:35 young gasr galaxies serve as the
146:37 birthplace of various black hole
146:40 phenomena whether they're luminous black
146:42 holes or intermediate Mass wandering
146:45 black holes hurtling through space or
146:48 the nearest black holes to Earth there
146:50 Origins can often be traced back to
146:52 these Bright Young
146:54 galaxies understanding the Cradle of
146:56 these Cosmic Giants helps us unlock the
146:58 Mysteries that black holes
147:02 hold now let's look at something really
147:05 rare there is a situation where black
147:07 holes
147:09 Collide in doing so they create a cosmic
147:12 Symphony of gravitational waves around
147:14 them that vibrate in the very fabric of
147:18 SpaceTime these waves first detected by
147:21 the laser interferometer gravitational
147:23 wave
147:24 observatory in 2015 opened a new
147:27 frontier in
147:28 astronomy however Recent research shows
147:31 that these waves interact in complex
147:34 ways as they propagate thereby testing
147:37 our understanding of gravity and the
147:39 general theory of
147:41 relativity traditionally scientists have
147:43 used linear models to describe these
147:46 waves however a new study has revealed
147:48 nonlinear effects that reveal a more
147:51 complex picture it's akin to the
147:54 difference between a calm pond and a
147:56 rough
147:57 sea in a calm Pond or linear Pond the
148:00 throw of a stone creates an isolated
148:02 Ripple in a stormy sea or nonlinear
148:06 however multiple forces interact to
148:09 create complex wave
148:11 patterns when black holes Collide they
148:15 emit unique frequencies or chirps
148:18 [Music]
148:23 these sounds are like individual notes
148:25 in our Cosmic Symphony each telling us
148:27 something about the properties of
148:29 colliding black holes they offer a new
148:31 way to test the limits of the general
148:33 theory of relativity and may even
148:35 provide clues to the nature of Dark
148:38 Matter recent discoveries have shown
148:40 that pairs of black holes and dwarf
148:42 galaxies are on a collision course these
148:45 dwarf galaxies attract gas that feeds
148:48 their black holes causing them to grow
148:50 even before they merge this process is a
148:54 microcosm of the larger universe where
148:57 galaxies and their Central black holes
148:59 grow in
149:00 tandem these colliding dwarf galaxies
149:03 offer a glimpse into the early Universe
149:05 which was filled with similar small
149:07 galaxies most of these eventually merged
149:10 to form larger galaxies like our Milky
149:13 Way understanding these processes helps
149:16 us piece together the cosmic mystery of
149:18 Galaxy and black hole
149:23 formation as we travel deeper into the
149:25 abyss of black holes we discover that
149:27 each type from luminous black holes of
149:30 intermediate Mass to wandering black
149:33 holes hurtling through space plays a
149:35 unique role in this great Cosmic
149:39 Symphony the next generation of
149:42 gravitational wave detectors will likely
149:44 deepen our understanding of these Cosmic
149:46 phenomena and of course each Discovery
149:49 from the frequencies they generate to
149:51 the nature of gravity itself undoubtedly
149:55 adds a new level to our understanding of
149:57 the
149:58 universe as our telescopic eyes become
150:01 sharper and computational models become
150:04 more sophisticated who knows what other
150:07 Cosmic Mysteries these Giants of the
150:10 cosmos will
150:15 reveal in the 21st century Humanity
150:18 finds itself in a crossroad at a moment
150:20 in history when we can see the stars but
150:23 not yet touch them born in the era
150:27 between exploring our own planet and the
150:30 possibility of reaching other worlds we
150:32 stand on the threshold of an
150:34 extraordinary
150:35 Journey it's not just about Rockets or
150:38 physics but about our survival and our
150:42 place in the
150:44 universe imagine a future in which Earth
150:47 faces an existential threat a catastroph
150:50 a collision with an asteroid the climate
150:52 collapse or something completely
150:56 unforeseeable our solution build
150:59 generation ships colossal spaceships
151:01 that serve as floating cities where
151:03 multiple Generations are born live and
151:07 die while traveling to another star to a
151:10 new
151:11 home Einstein's special theory of
151:14 relativity tells us that traveling
151:16 faster than light is
151:18 impossible however space is within our
151:20 reach even at a speed that is only a
151:23 fraction of the speed of
151:25 light generation ships traveling at a
151:28 significant fraction of light speed
151:30 could travel vast distances between
151:32 stars with Technologies such as matter
151:35 anti-matter engines compact Fusion
151:38 drives and even black hole propulsion
151:41 what seems like science fiction could
151:43 become a reality but these ships are not
151:46 just vessels they are lifeboats for
151:49 Humanity
151:50 they must sustain life for centuries
151:53 perhaps Millennia facing the challenge
151:56 of space travel genetic diversity and
151:58 mental
151:59 health each ship will be a microcosm of
152:02 Earth with its social structures
152:05 cultural heritage and daily
152:07 challenges what would it take to build
152:10 such a ship how can its inhabitants
152:12 survive and
152:14 thrive join us as we delve into the
152:17 intricacies of interstellar travel with
152:19 without exceeding the speed of light
152:21 today we'll try to unlock the secrets of
152:24 how Humanity can one day travel to the
152:27 stars but not in an instant but through
152:33 generations planning for Interstellar
152:35 travel is not only about technology but
152:38 also about predicting why such travel
152:41 might become necessary foreseeable
152:43 threats to humanity survival May Force
152:45 us to seek Refuge outside our solar
152:48 system understanding these threat
152:49 threats will help us prepare for
152:51 possible future scenarios that could
152:53 force Humanity to embark on such an
152:55 extraordinary
152:57 Journey one of the most immediate
152:59 threats comes from space itself Comet
153:03 impacts throughout Earth's history
153:05 collisions with comets and asteroids
153:07 have caused mass extinctions and major
153:10 climate shifts a strong enough Collision
153:13 could make earth uninhabitable forcing
153:15 us to seek a new home Among the
153:18 Stars another series his threat is
153:20 climate
153:21 collapse human activity has already led
153:24 to significant changes in our climate
153:26 Rising temperatures melting polar ice
153:30 caps and increasingly severe weather
153:33 events if these Trends are not
153:36 controlled Earth could become hostile to
153:39 human life making searching for
153:41 habitable exoplanets a top
153:44 priority technological progress while
153:47 bringing enormous benefits also carries
153:49 signif ific risks advances in artificial
153:52 intelligence biotechnology and
153:55 autonomous systems could lead to
153:57 scenarios where Humanity faces a threat
153:59 from its own
154:01 Creations uncontrolled AI or engineered
154:05 pathogens could become existential risks
154:08 leading to the need to establish human
154:10 colonies on Distant Worlds as a our
154:16 species in search of a new home proximus
154:19 and T B is a prime candidate located
154:23 just 4.24 light years away in the alpha
154:26 centor system it is the closest known
154:28 exoplanet that's in the habitable zone
154:30 of its Star as many know this Zone often
154:34 referred to as the goldilock zone is the
154:36 area around a star where conditions may
154:39 be optimal for the existence of liquid
154:41 water an essential ingredient of life
154:44 for
154:46 Humanity proximus centor B was
154:48 discovered in 2016
154:50 and has been the subject of intense
154:52 study ever since it orbits a red dwarf
154:55 star that's smaller and colder than our
154:58 sun meaning the planet would have to be
155:00 much closer to W star to be in a
155:02 habitable
155:03 zone this proximity while favorable for
155:07 retaining heat also exposes the planet
155:09 to flares and radiation which must be
155:12 considered when planting human
155:14 habitation current Research indicates
155:17 that the planet has a mass similar to
155:18 Earth sand may have a rocky surface
155:21 however much about it remains unknown
155:24 including the composition of its
155:25 atmosphere and the presence of liquid
155:28 water future missions and observations
155:31 will be needed to collect more data and
155:33 assess its suitability for
155:35 Life sending a spacecraft to our nearest
155:38 neighboring star involves not only
155:40 covering the distance but also ensuring
155:43 that the distance is suitable for human
155:45 life this requires a multifaceted
155:48 approach that includes Rob robotic
155:50 probes and telescopes to gather detailed
155:52 information about the planet's
155:53 environment these missions will help
155:55 determine the feasibility of
155:57 establishing a human colony and the
155:59 preparations necessary for long-term
156:02 survival proximus and Tory B was chosen
156:06 as our Target because of its relative
156:08 proximity and potential habitability
156:12 however reaching and inhabiting the
156:14 distant world will be a Monumental task
156:17 requiring an unprecedented level of plan
156:20 Innovation and
156:25 collaboration the dream of exploring the
156:27 Stars has always been tempered by the
156:29 harsh realities of physics and time
156:32 traditional concepts of space travel
156:34 where one crew sets off and reaches
156:36 their destination within their lifetime
156:38 seem increasingly impractical when it
156:41 comes to the vast distances between the
156:44 Stars this is where the concept of
156:46 intergenerational ships come into play a
156:49 bold and Innovative solution to the
156:52 problem of long-distance space
156:54 travel generational ships also known as
156:58 intergenerational or generation ships
157:00 are designed to keep people alive for
157:02 centuries or even Millennia these ships
157:06 are self-sustaining ecosystems with not
157:08 only one crew on board but all of their
157:12 descendants life on a generational ship
157:15 is designed to mimic a small
157:17 self-contained world with with living
157:20 quarters food production water Recycling
157:23 and social
157:25 systems the concept is simple yet
157:28 profound as the original crew ages and
157:30 eventually passes away their children
157:33 and their children's children continue
157:36 the
157:36 mission this life cycle ensures that for
157:39 many generations the ship will continue
157:42 its journey and each new generation will
157:45 be trained and prepared to maintain the
157:47 ship and eventually reach its
157:48 destination
157:51 this approach to space travel requires
157:53 careful planning and robust systems to
157:55 ensure that the inhabitants survive and
157:58 thrive every aspect of life must be
158:00 carefully considered from genetic
158:03 diversity to ensure a healthy population
158:06 to cultural and educational programs
158:08 that preserve and pass on vital
158:10 Knowledge and
158:12 Skills Einstein's special theory of
158:15 relativity presents a serious problem
158:17 for traveling faster than light
158:19 according to this Theory as objects
158:21 approach the speed of light their mass
158:24 increases and they require exponentially
158:26 more energy to continue
158:28 accelerating this effectively makes
158:30 traveling faster than the speed of light
158:32 impossible with our current
158:34 understanding of physics generational
158:37 ships offer a practical solution within
158:39 the framework of Einstein's theory by
158:42 accepting the duration of space travel
158:44 and planning for generations of Life
158:46 aboard such ships Humanity can aspire
158:49 prior to distant
158:51 Stars such an approach recognizes the
158:54 limitations imposed by the theory of
158:55 relativity while the same time
158:58 supporting the resilience and
158:59 adaptability of the human
159:05 Spirit traveling to the Stars requires
159:07 overcoming significant challenges not
159:10 the least of which is the vast distance
159:12 between celestial
159:14 bodies to make Interstellar travel
159:16 feasible within a human lifetime we have
159:19 to take a closer look at the advanced
159:20 propulsion techniques and the Intriguing
159:23 phenomenon of relativistic time
159:27 dilation relativistic time dilation is a
159:30 consequence of Einstein's special theory
159:33 of relativity when an object approaches
159:35 the speed of light time on board is
159:38 slowed down compared to the time
159:41 experienced by an observer at
159:43 rest this means that for a spacecraft
159:46 traveling in a significant fraction of
159:48 the speed of light the travel time of
159:50 the crew will be shortened compared to
159:53 those who remain on
159:54 Earth for example if a ship could travel
159:57 at 90% of the speed of light time
160:00 dilation would cause one year aboard the
160:03 ship to be equivalent to more than 2
160:05 years on
160:06 Earth because of this effect
160:08 Interstellar Journeys stretching over
160:10 decades or centuries may seem shorter to
160:13 the crew although they do not shorten
160:15 the actual
160:17 distance several Advanced propulsion
160:20 methods have been proposed to achieve
160:22 the high speeds required for
160:23 Interstellar travel each method has its
160:26 own set of problems and potential
160:29 advantages for example antimatter
160:32 propulsion involves the annihilation of
160:34 matter and antimatter with the release
160:36 of enormous amounts of energy this
160:39 reaction releases energy much more
160:41 efficiently than chemical Rockets
160:44 potentially allowing spacecraft to reach
160:46 significant fractions of the speed of
160:48 light
160:49 however producing and storing sufficient
160:52 antimatter remains a major technical
160:55 hurdle on the other hand compact Fusion
160:58 reactors use nuclear fusion the same
161:01 process that powers the Sun to produce
161:04 energy by combining light Atomic nuclei
161:08 such as hydrogen with heavier nuclei
161:11 these reactors could provide sustained
161:14 and Powerful thrust for spacecraft while
161:17 controlled Fusion technology is promised
161:19 it's still under development and
161:21 building a compact and reliable reactor
161:24 suitable for space flight is another
161:26 major engineering
161:28 challenge black hole propulsion is a
161:31 more speculative concept that involves
161:34 harnessing the enormous gravitational
161:36 energy of a black hole to propel a
161:39 spacecraft the idea is to create a small
161:42 artificial black hole and harness the
161:45 energy of the Hawking radiation it emits
161:49 theoretically this method could provide
161:51 continuous and Powerful acceleration but
161:54 the technology to create and control
161:56 artificial black holes is still in the
161:58 realm of something fantastic far beyond
162:01 our current
162:04 capabilities however the problems don't
162:06 end with thrusters traveling at near
162:09 light speed is frought with many
162:12 dangers one of the main ones is the
162:14 threat posed by Interstellar particles
162:17 these high speeds even tiny part
162:19 particles can cause significant damage
162:21 in a collision spacecraft must be
162:23 equipped with Advanced shielding to
162:25 protect against these high energy
162:29 collisions radiation is another serious
162:31 Hazard high-speed space travel exposes
162:34 the crew to intense Cosmic radiation
162:37 that can have deleterious health
162:40 effects effective radiation protection
162:42 and possibly even medical intervention
162:44 will be a necessity to keep the crew
162:46 healthy during long duration missions
162:50 maintaining the structural Integrity of
162:52 the spacecraft over the long term is
162:55 also critical the stresses and strains
162:58 of high-speed flight can weaken
163:00 materials over time requiring Advanced
163:03 Construction techniques and regular
163:05 maintenance to keep the spacecraft safe
163:07 and functional throughout the
163:10 voyage despite these formidable
163:12 challenges the pursuit of interstellar
163:15 travel drives human Ingenuity and
163:18 ambition
163:19 [Music]
163:20 by researching and developing Advanced
163:22 propulsion techniques and overcoming the
163:24 dangers of high-speed travel we're
163:26 taking crucial steps toward reaching for
163:29 the stars and expanding our presence in
163:35 space choosing the right propulsion
163:38 system for Interstellar travel is one of
163:40 the most important decisions in Mission
163:43 planning the propulsion system
163:45 determines the speed duration and
163:47 feasibility of the miss
163:49 so it's important to explore both best
163:52 practices and traditional
163:55 methods one promising approach is to
163:57 scale up the traditional propulsion
164:00 Technologies NASA's Parker solar probe
164:03 uses a combination of chemical
164:05 propulsion and gravitational assists to
164:08 achieve unprecedented
164:10 speeds the probe is traveling at more
164:12 than 430,000
164:14 mph which is approximately
164:18 0.064% set of the speed of light and
164:21 makes it the fastest man-made object to
164:24 date its propulsion system is based on
164:27 hydren thrusters powered by solar energy
164:31 which showed the potential of using
164:32 existing technology for high-speed space
164:37 travel gravitational assists or
164:39 slingshot Maneuvers use the gravity of
164:42 planets or other celestial bodies to
164:44 increase the speed of a spacecraft
164:46 without expending additional fuel
164:49 by carefully planning a trajectory a
164:51 spacecraft can gain significant speed
164:54 reducing travel time over vast
164:57 distances this technique while
165:00 insufficient by itself for Interstellar
165:02 travel can be an important component of
165:05 a multi-stage propulsion
165:08 strategy scaling up these traditional
165:10 Technologies involves developing more
165:12 efficient thrusters and larger amounts
165:15 of
165:17 fuel another promising area is
165:19 innovation in ion thrusters which use
165:23 electric fields to accelerate ions and
165:25 create thrust ion thrusters are highly
165:29 efficient and can operate for long
165:31 periods making them suitable for long
165:33 duration
165:34 missions the combination of these
165:36 Advanced conventional methods could be a
165:39 practical solution for the initial
165:41 stages of interstellar
165:43 travel for faster travel we must
165:45 consider more advanced propulsion
165:47 methods such as nuclear propulsion one
165:50 of the most intriguing Concepts in this
165:52 category is the Orion Project first
165:55 proposed in the
165:57 1950s this method involves a series of
166:00 thermonuclear explosions behind the
166:02 spacecraft Each of which creates a
166:04 powerful thrust to propel the spacecraft
166:08 forward the Orion Project uses a massive
166:11 Pusher plate at the rear of the
166:13 spacecraft designed to absorb shock
166:16 waves from explosions and convert them
166:18 into into forward momentum by repeating
166:21 this process in a controlled manner the
166:23 spacecraft will be able to reach
166:25 significant fractions of the speed of
166:27 light drastically shortening the flight
166:29 time to nearby
166:31 Stars although the concept is
166:33 theoretically sound many Technical and
166:36 safety problems still have to be solved
166:38 controlling the timing and directions of
166:41 explosions requires precise design and
166:44 the spacecraft in turn must be designed
166:46 to withstand enormous loads
166:49 in addition the environmental impact of
166:51 launching such a vehicle from Earth must
166:54 be carefully considered which may also
166:56 require space launch
166:59 platforms another Fusion engine concept
167:02 is the dataless project which involves
167:04 using Fusion reactions to propel a
167:07 spacecraft this method involves the use
167:09 of small pellets of Fusion fuel such as
167:11 detarium and helium 3 which are ignited
167:15 by electron beams to create a constant
167:17 thrust the datalist project aims to
167:20 reach speeds of up to 12% of the speed
167:22 of light which would make it possible to
167:24 travel to the nearest Stars within a
167:26 human
167:27 Lifetime Fusion propulsion offers a more
167:30 controllable and potentially safer
167:32 alternative to the Orion method however
167:35 the technology to build reliable and
167:37 efficient Fusion reactors for space
167:39 flight is still under
167:41 development significant advances in
167:44 Fusion research and Engineering are
167:45 needed to make this approach viable for
167:47 Interstellar mission
167:50 choosing the right propulsion system is
167:52 a balance between feasibility safety and
167:56 performance traditional methods such as
167:59 those used in the Parker solar probe
168:01 offer practical short-term
168:03 Solutions while Advanced Fusion
168:05 propulsion Concepts such as the Orion
168:08 and dataless projects promise the
168:10 potential for faster and more ambitious
168:13 Interstellar
168:17 travel ensuring the survival and health
168:20 of the crew over multiple Generations is
168:23 a Cornerstone of generational ship
168:25 planning one of the most important
168:28 aspects is maintaining genetic diversity
168:30 which is necessary to prevent inbreeding
168:33 and genetic diseases that could
168:34 jeopardize the
168:36 mission to solve the problem of genetic
168:39 diversity scientists use Monte Carlo
168:43 simulations these models use statistical
168:46 methods to simulate and predict genetic
168:49 variability over many generations by
168:52 introducing various parameters such as
168:54 initial population size mutation rates
168:57 and reproductive
168:58 patterns these simulations can provide
169:01 insight into the genetic health of a
169:03 population over
169:04 time Monte Carlo simulations help
169:07 determine the minimum population size
169:09 needed to maintain genetic diversity and
169:12 prevent inbreeding depression they also
169:15 take into account possible random events
169:17 such as accidents or disease that could
169:20 affect the population such modeling is
169:22 essential to creating a sustainable
169:25 human Colony that can Thrive for
169:27 centuries maintaining genetic diversity
169:30 requires careful planning of
169:32 reproductive strategies and potential
169:34 genetic
169:36 screening the crew must be educated
169:38 about the importance of genetic health
169:40 and the steps necessary to maintain it
169:43 this includes monitoring genetic
169:45 diversity and making informed decisions
169:47 about partnership and
169:50 reproduction research shows that a
169:52 minimum initial population of at least
169:54 100 individuals is required to maintain
169:57 genetic health over several
170:00 Generations this figure comes from
170:02 Studies by scientists such as Frederick
170:04 Moran and Camille balui who have
170:07 extensively studied the genetic dynamics
170:09 of small isolated
170:12 populations in their research Moran and
170:14 balui use Monte Carlo simulations to
170:17 explore different scenario I including
170:20 different population sizes and
170:21 reproductive
170:23 strategies their study shows that with a
170:25 balanced sex ratio and optimal
170:27 reproductive rate an initial population
170:30 of at least 100 individuals can maintain
170:33 a healthy gene
170:34 pool this population size ensures that
170:37 genetic drift and inbreeding will not
170:40 jeopardize the health and viability of
170:42 future
170:44 Generations an initial population of 100
170:47 individuals should grow to 500
170:49 individuals over several Generations
170:51 this growth is necessary to create a
170:53 stable and resilient population that can
170:56 cope with unforeseen
170:58 challenges the modeling takes into
171:00 account various factors such as random
171:03 genetic mutations environmental
171:06 influences and possible catastrophes to
171:09 ensure the sustainability of the
171:11 population designing a generational ship
171:14 to accommodate a growing population
171:16 involves planning for adequate living
171:18 space
171:19 resources and social structures the ship
171:22 should provide educational health and
171:25 recreational facilities to support the
171:27 physical and mental well-being of the
171:29 crew this includes collaborative
171:31 activity spaces and private living
171:34 quarters to provide a balance between
171:36 social interaction and personal
171:39 privacy beyond the physical
171:41 infrastructure it's vital to maintains
171:43 social cohesion and cultural continuity
171:46 the crew must develop a shared sense of
171:48 purpose and identity to Foster
171:50 cooperation and
171:52 sustainability cultural and educational
171:55 programs play a key role in maintaining
171:57 the knowledge and values necessary for
172:00 Mission success effective crew and
172:03 population planning is essential to the
172:05 success of a generational ship using
172:07 Advanced genetic simulations and
172:09 research we can ensure that the
172:11 population remains healthy and viable
172:14 with careful planning and a commitment
172:16 to maintaining social and genetic health
172:18 Humanity can thrive on the path to the
172:20 Stars ensuring the survival and
172:23 prosperity of future
172:29 Generations above all however designing
172:32 a Generation ship capable of sustaining
172:34 human life for centuries involves
172:36 creating a self-sustaining environment
172:39 that mimics the basic aspects of life on
172:41 Earth this includes creating artificial
172:44 gravity producing food and recycling
172:47 vital resources such as Water and Air
172:50 these systems must be reliable efficient
172:53 and able to operate autonomously for
172:54 long
172:56 periods one of the most important
172:58 aspects of ship design is the creation
173:00 of artificial gravity to maintain the
173:02 health and wellness of the crew
173:05 prolonged exposure to microgravity can
173:07 lead to muscle atrophy loss of bone
173:09 density and other health
173:12 problems to counteract these effects
173:14 generation ships can use rotating media
173:17 to create a centrifugal force that
173:19 mimics Earth's
173:21 gravity the most practical design
173:23 involves a large rotating ring or
173:25 cylindrical section where the crew lives
173:27 and works as the structure rotates at a
173:31 certain speed centrifugal force pushes
173:33 the occupants outward simulating the
173:36 effect of gravity for example a ring
173:38 with a radius of 100 yards must rotate
173:41 at a rate of about three revolutions per
173:43 minute to create an artificial gravity
173:46 of 1G similar to Earth's
173:49 this design not only helps maintain
173:51 physical health but also provides a
173:53 familiar environment that can alleviate
173:55 the psychological challenges of living
173:58 in
173:59 space rotating habitats can include
174:02 living quarters recreational areas and
174:04 workspaces designed to optimize the use
174:07 of available space and
174:10 resources reliable and efficient food
174:13 production systems are also required to
174:15 sustain populations for generations to
174:18 come
174:19 Hydroponic and aeroponic systems offer
174:22 solutions for growing crops without soil
174:24 using nutrient Rich water or Mist to
174:28 nourish the
174:29 plants these methods are highly
174:31 efficient use less water in space than
174:34 traditional farming and are well suited
174:37 to the controlled environment of our
174:39 ship hydroponic systems involve growing
174:42 plants and nutrient Solutions with their
174:44 Roots suspended in water aeroponic
174:47 systems on the other and use a fine Mist
174:49 to deliver nutrients directly to the
174:52 roots both systems can grow a wide range
174:55 of crops from leafy greens to root
174:58 vegetables providing balanced nutrition
175:00 for the
175:01 crew these systems can be automated and
175:04 monitored to maintain optimal growing
175:07 conditions ensuring a stable and
175:09 reliable food supply in addition genetic
175:12 modification and breeding will be able
175:14 to increase the yield and nutritional
175:16 value of crops
175:19 efficient water and air recycling is
175:21 critical to the sustainability of a
175:23 Generation
175:24 ship water recycling systems must be
175:28 capable of recovering and treating waste
175:30 water ensuring a continuous supply of
175:32 clean water for drinking cooking and
175:36 irrigation Advanced Filtration and
175:38 purification Technologies such as those
175:40 used on the International Space Station
175:43 are already achieving high levels of
175:45 efficiency on the ISS for example the
175:48 Water Reclamation system can recycle up
175:51 to 98% of Wastewater including urine and
175:55 sweat this level of efficiency is
175:58 necessary for long duration missions
176:00 when resupply from Earth is not feasible
176:03 ships of future Generations will need to
176:05 improve this efficiency even further
176:07 aiming for near complete recycling to
176:09 minimize the need for large water
176:12 reserves air recycling is equally
176:15 important requiring systems that can
176:17 remove carbon dioxide and replenish
176:20 oxygen natural systems such as
176:23 photosynthesis and plants can be
176:25 integrated with artificial CO2 scrubbers
176:27 to maintain a balanced atmosphere plants
176:31 in turn not only provide oxygen but also
176:33 contribute to the psychological
176:35 well-being of the crew by providing a
176:37 connection to
176:39 Nature projects such as Biosphere 2 have
176:43 demonstrated the potential for creating
176:45 closed ecosystems in which plants humans
176:47 and micro organisms coexist by recycling
176:51 air water and
176:52 nutrients although Biosphere 2 faced
176:55 some challenges it demonstrated the
176:57 feasibility of such systems providing
177:00 valuable lessons for the design of life
177:03 support systems on generational
177:06 ships creating a self-sustaining
177:09 generational ship requires integrating
177:11 advanced technology with natural
177:13 processes to ensure the health and
177:15 well-being of its inhabitants
177:18 artificial gravity efficient food
177:20 production and reliable Disposal Systems
177:23 are the very pillars of this design
177:26 enabling Humanity to embark on a
177:28 long-term Journey to the
177:34 Stars ensuring the success of a
177:36 multi-generational mission goes beyond
177:39 the physical and technological aspects
177:41 of the ship it requires meeting the
177:44 mental social and educational needs of
177:47 the crew ensuring their health
177:49 motivation and cohesion throughout the
177:52 long
177:53 Voyage isolation and confined spaces can
177:58 significantly affect morale and mental
178:00 health lack of new stimuli and prolonged
178:04 separation from Earth can lead to
178:06 feelings of loneliness depression and
178:10 anxiety addressing these issues is
178:12 critical to maintaining a stable and
178:14 motivated
178:16 crew virtual ual reality Technologies
178:19 offer promising solutions for mental
178:21 health and cultural Connection by
178:24 creating immersive simulations of
178:26 terrestrial environments virtual reality
178:28 or VR can provide a sense of escape and
178:33 familiarity crew members will be able to
178:35 see forests oceans and even social
178:38 Gatherings helping to alleviate feelings
178:40 of isolation and maintain a connection
178:42 to their home
178:45 planet artificial intelligence can also
178:47 play an important role in supporting
178:49 crew mental
178:50 health AI therapists such as NASA's
178:54 Simon 2.0 can offer individual
178:57 counseling monitor psychological
178:59 well-being and suggest strategies for
179:01 coping with stress and interpersonal
179:04 conflict these AI systems can adapt and
179:07 learn from each generation providing
179:10 continuity and consistency and mental
179:12 health
179:14 support ensuring the intergenerational
179:17 transfer of knowledge skills is critical
179:19 to Mission
179:20 sustainability a comprehensive education
179:23 system must be put into place to ensure
179:25 that each new generation receives the
179:28 necessary skills to operate and maintain
179:30 the ship as well as the knowledge to
179:32 continue research and
179:34 exploration this should include formal
179:37 education practical training and the
179:39 preservation of cultural and historical
179:45 knowledge embarking on an interst Voyage
179:48 requires not only technological prowess
179:51 but also a deep commitment to the human
179:54 Spirit by addressing the mental social
179:57 and educational needs of the crew we
179:59 ensure the resilience and connection of
180:02 each generation that carries the torch
180:04 of exploration and
180:06 survival advanced technology such as
180:09 virtual reality and artificial
180:11 intelligence support combined with
180:13 strong cultural and social structures
180:16 will create the foundation for a
180:18 thriving Community across
180:21 Generations when we reach beyond our
180:23 solar system a harmonious blend of
180:26 innovation and Humanity will lead us to
180:28 new worlds securing our future as an
180:32 Interstellar species
