0:00 an object so powerful so dense that
0:02 nothing not even light can escape its
0:05 grasp black holes lurk in the depths of
0:08 space with an insatiable hunger for
0:11 anything that comes too close they are
0:13 invisible Giants silently bending space
0:16 and time swallowing stars and reshaping
0:19 entire
0:20 galaxies their presence can be felt
0:23 across the cosmos including our own
0:25 Milky Way let's Journey Into the Heart
0:28 of these Cosmic monsters exploring the
0:30 different types of black holes and their
0:32 strange properties with real life
0:34 examples that defy belief from the
0:37 massive black hole at our galaxy Center
0:39 to the mysterious Phantom black holes
0:42 drifting in
0:43 Space by the end you'll see why black
0:46 holes are some of the most feared and
0:49 fascinating objects in the
0:51 universe the enigmatic Stellar black
0:53 holes born from dying Stars black holes
0:57 have a way of capturing our imagination
1:00 they were once just theoretical
1:01 predictions but over the years
1:03 astronomers have uncovered more and more
1:05 evidence that black holes are very real
1:08 and they're scattered throughout our
1:10 universe these Cosmic Giants form when
1:12 massive stars run out of fuel and
1:14 collapse under their own gravity
1:16 compressing all their matter into a
1:18 single point known as a
1:20 singularity The Singularity is a place
1:22 of infinite density and gravity so
1:25 intense that all matter is crushed into
1:27 an unimaginably small space
1:30 around this point lies The Event Horizon
1:33 a boundary where gravity is so strong
1:35 that not even light can escape Beyond
1:38 The Event Horizon scientists can only
1:40 speculate on what truly happens some
1:43 suggest that everything that falls into
1:45 a black hole is compressed to a single
1:47 point crushed to an infinite density at
1:50 the
1:51 singularity others believe that black
1:53 holes might be connected to wormholes
1:55 that lead to other parts of the universe
1:57 or even to different universes or
2:00 together all we know is that once
2:02 something crosses that invisible line
2:05 it's beyond our reach once anything
2:08 crosses the Event Horizon whether it's a
2:10 beam of light a planet or even a star
2:14 it's lost forever our best scientific
2:17 theories like Einstein's theory of
2:19 relativity explain how gravity works on
2:21 a large scale and predict the formation
2:23 of black holes but when it comes to the
2:26 singularity these theories start to fall
2:28 apart at at this level our understanding
2:31 of physics breaks down completely and
2:33 the usual laws of nature no longer apply
2:37 it's as if black holes exist as a kind
2:39 of wall in our knowledge black holes
2:42 come in various sizes from Stellar black
2:44 holes a few times more massive than our
2:46 sun to super massive black holes that
2:48 weigh billions of times more these super
2:51 massive Giants sit at the heart of
2:53 galaxies shaping the lives of stars and
2:56 planets around them black holes can feed
2:59 on nearby stars and matter growing
3:01 larger and more powerful over time
3:05 Stellar black holes though only one type
3:07 in the wide spectrum of black holes are
3:10 some of the most iconic and well studied
3:12 when a massive star one with at least
3:15 eight times the mass of our Sun reaches
3:17 the end of its life it undergos a
3:20 transformation that's as violent as it
3:21 is final for millions of years these
3:24 Stars Burn hot and bright fusing
3:26 hydrogen into helium and then into
3:28 heavier elements with the force of
3:30 nuclear fusion pushing outwards against
3:32 the force of gravity but eventually they
3:36 reach a point where they can no longer
3:37 sustain this Fusion process with no more
3:40 fuel to burn the outward pressure
3:42 disappears and gravity takes over
3:45 completely the core collapses inward
3:47 under its own weight and in a fraction
3:49 of a second it becomes so dense that a
3:52 black hole is borne and the rest of the
3:54 star is blown outward in an explosion
3:57 called a supernova that can briefly
3:59 outshine entire galaxies but what's left
4:03 behind is a Darkness so powerful that
4:05 nothing can escape it the newly formed
4:07 black hole may start small but as it
4:10 consumes nearby gas dust and sometimes
4:13 even entire Stars it grows becoming more
4:16 massive and increasing the size of its
4:19 Event
4:20 Horizon these Stellar black holes vary
4:22 in size but they generally contain about
4:25 3 to 10 times the mass of our
4:27 sun even though they are are relatively
4:30 small compared to super massive black
4:32 holes their gravitational pull is still
4:35 powerful and far-reaching in some cases
4:38 Stellar black holes exist alone in space
4:41 unnoticed and undetectable without any
4:45 nearby material to reveal their presence
4:48 but in other cases a stellar black hole
4:50 has a partner a nearby star that it
4:52 orbits when a black hole and a star
4:55 orbit each other the immense gravity of
4:57 the black hole can start to pull matter
4:59 off the star this material spirals
5:02 inward forming an accretion disc a
5:05 swirling glowing ring of gas and dust
5:07 that heats up to extreme temperatures as
5:09 it approaches the black hole from a
5:12 distance these systems appear as bright
5:14 x-ray sources which can be detected by
5:17 telescopes here on
5:19 Earth observing these x-rays allows
5:22 scientists to study the black hole's
5:24 behavior and even estimate its mass
5:28 these x-ray binaries as they're called
5:30 are some of the best evidence we have
5:32 for the existence of Stellar black holes
5:35 the intense light they produce reveals
5:37 details about the speed and pattern of
5:39 the material spiraling inward which in
5:42 turn provides insights into the physics
5:44 of the black hole
5:45 itself the intense gravity of a stellar
5:48 black hole creates a gravitational well
5:51 in space bending the paths of nearby
5:54 objects a planet orbiting close to a
5:56 black hole would experience strong
5:58 gravitational Tides stretching and
6:01 squeezing as it moved through the uneven
6:03 gravitational field if a planet ventured
6:06 too close it could be torn apart
6:08 entirely its debris spiraling into the
6:11 black hole in a final violent
6:13 encounter fortunately such events are
6:16 rare and most Stellar black holes drift
6:19 through space far from any potential
6:21 victims in some galaxies Stellar black
6:24 holes are scattered throughout the arms
6:26 and discs hidden among billions of stars
6:30 their influence on their Galactic
6:31 neighborhoods may be small but each one
6:34 represents the end point of a massive
6:36 star's life a kind of cosmic gravestone
6:39 marking where a sun once burned bright
6:42 Stellar black holes remain largely the
6:45 same size as when they formed this makes
6:47 them stable enduring objects that can
6:50 drift through space unchanged for eons
6:53 holding onto the secrets of their
6:55 formation in the vast expanse of space
6:58 some Stellar black hole may even drift
7:00 alone completely undetectable These
7:03 Quiet black holes pose a special
7:05 challenge to astronomers because without
7:07 an accretion disc or a partner star they
7:10 don't produce any detectable radiation
7:13 they are truly invisible their presence
7:16 inferred only by their gravitational
7:18 effects or in some cases by the bending
7:21 of light from distant stars behind
7:23 them this phenomenon known as
7:26 gravitational lensing occurs when a
7:28 black hole passes between between us and
7:30 a distant star acting like a magnifying
7:32 glass and distorting the star's light by
7:35 observing these distortions scientists
7:38 can sometimes infer the presence of a
7:39 stellar black hole even if it is
7:41 otherwise hidden in some cases Stellar
7:44 black holes can merge with each other or
7:47 with neutron stars creating
7:48 gravitational waves that Ripple across
7:51 space these waves first detected in 2015
7:54 have opened up a new way of studying the
7:56 cosmos allowing scientists to observe
7:59 collisions between black holes
8:01 directly each merger is like a seismic
8:04 event in space a brief but Powerful
8:07 release of energy that Echoes Across the
8:09 Universe these mergers are rare but when
8:12 they happen they offer a unique
8:14 opportunity to learn about black hole
8:16 properties such as their mass and
8:19 spin intermediate black holes the
8:22 missing links of the
8:24 universe intermediate black holes
8:27 sometimes called the missing links of
8:28 the cosmos
8:30 occupy a unique space in the black hole
8:32 family these black holes are neither as
8:34 small as Stellar black holes nor as
8:37 massive as the super massive black holes
8:39 that lie at the centers of galaxies
8:41 instead they sit in between with masses
8:44 ranging from hundreds to thousands of
8:46 times that of our
8:47 sun despite their predicted existence
8:50 finding and studying intermediate black
8:52 holes has proven to be incredibly
8:55 challenging if intermediate black holes
8:57 do exist they might act as Stepping
8:59 Stones between small Stellar black holes
9:02 and the massive Giants that dominate The
9:04 Centers of
9:05 galaxies the idea is that over time
9:08 smaller black holes could merge or
9:10 gather enough material to grow into
9:12 intermediate sizes which might
9:14 eventually lead to the formation of
9:16 super massive black holes but if that's
9:19 the case why are they so hard to find
9:22 shouldn't the universe be full of these
9:24 midsized black holes especially in the
9:27 bustling areas of space where galaxies
9:29 Collide or where many stars are packed
9:32 together one of the biggest challenges
9:35 in finding intermediate black holes is
9:37 that they are not as active as their
9:39 larger
9:41 counterparts super massive black holes
9:43 often have huge accretion discs of gas
9:45 and dust swirling around them emitting
9:48 vast amounts of light and energy that
9:50 make them visible even across large
9:53 distances but intermediate black holes
9:56 especially if they are isolated or in
9:58 quieter parts of SP face might not have
10:00 enough surrounding material to create
10:02 this same type of brilliant display
10:04 without an accretion disc or bright
10:06 x-ray signals an intermediate black hole
10:09 would be almost invisible blending into
10:12 the background of space and eluding our
10:15 telescopes however there are some
10:17 indirect ways to detect these elusive
10:20 objects one of the primary methods is by
10:22 looking for gravitational effects when
10:25 an intermediate black hole passes near a
10:27 star or a cloud of gas its gravity can
10:30 cause subtle shifts in the objects
10:32 around it astronomers can sometimes spot
10:35 these disturbances by watching for
10:36 changes in the orbits of stars or the
10:39 shape of gas clouds another method
10:42 involves looking for gravitational waves
10:44 that are produced when black holes merge
10:47 if a stellar black hole were to collide
10:49 with an intermediate black hole the
10:51 event would create gravitational waves
10:53 strong enough to be detected by
10:55 observatories on Earth these waves would
10:58 offer hints about the sign sizes and
10:59 locations of intermediate black holes
11:02 even if we can't see them directly
11:05 despite the difficulty in detecting them
11:07 there have been a few promising
11:09 candidates for intermediate black holes
11:12 one well-known case is a black hole
11:14 found in the Dense Star cluster known as
11:16 Omega centu located in our own
11:20 Galaxy this cluster contains hundreds of
11:23 thousands of stars packed tightly
11:25 together making it a prime location for
11:27 black holes to form some observations
11:30 have suggested that Omega centu may
11:32 contain an intermediate black hole
11:34 several thousand times the mass of our
11:36 sun at its Center exerting gravitational
11:39 influence on the surrounding Stars while
11:42 the evidence isn't conclusive it gives
11:44 scientists hope that intermediate black
11:46 holes might be lurking in other similar
11:49 star
11:50 clusters in the Galaxy M82 astronomers
11:54 observed a powerful x-ray source that
11:56 appeared too bright to be caused by a
11:58 stellar black hole
11:59 but was too small to be a super massive
12:02 black
12:02 hole this object named M82 X1 could be
12:07 an intermediate black hole shining
12:09 brightly as it consumes material from a
12:11 nearby star the clearest evidence
12:14 however comes from gw1
12:17 9521 a gravitational wave signal from
12:20 2019 which indicated that about 17
12:22 billion light years away an 85 solar
12:25 mass black hole had merged with one that
12:28 was 66 solar masses resulting in the
12:31 formation of a 142 solar mass black hole
12:35 this new black hole was about nine solar
12:38 masses smaller than the combination of
12:40 the two because that mass was released
12:42 as energy in the form of gravitational
12:44 waves the importance of intermediate
12:47 black holes goes beyond simply filling
12:49 in the gaps in black hole sizes these
12:52 midsized objects could play a crucial
12:54 role in shaping galaxies if intermediate
12:57 black holes exist in the centers of star
12:59 clusters or small galaxies they could
13:01 help to merge and organize the
13:03 surrounding Stars contributing to the
13:05 overall structure of
13:07 galaxies when galaxies Collide
13:10 intermediate black holes from each
13:12 Galaxy could eventually find each other
13:15 merging and potentially leading to the
13:17 formation of a super massive black hole
13:20 in the merged Galaxy's
13:22 Center the process of Galaxy formation
13:25 and evolution is still a major mystery
13:28 in astrophysics
13:29 and intermediate black holes might be
13:32 one of the missing pieces if these black
13:34 holes were more common in the early
13:36 Universe they could have provided the
13:38 seeds for today's super massive black
13:41 holes the early Universe was a chaotic
13:44 Place full of young massive stars and
13:47 dense gas clouds that could have easily
13:49 created intermediate black holes through
13:51 frequent collisions and star deaths over
13:54 billions of years these intermediate
13:57 black holes could have grown by
13:58 consuming in gas and merging with each
14:00 other gradually forming the super
14:02 massive black holes we see today super
14:05 massive black holes Giants of the
14:07 galactic core super massive black holes
14:10 are the true Giants of the universe they
14:13 dominate The Centers of galaxies
14:15 including our own Milky Way these
14:18 enormous black holes can weigh millions
14:20 or even billions of times more than our
14:22 sun their sheer size and power make them
14:25 some of the most influential objects in
14:27 the cosmos not just for their gravity
14:30 but for the way they shape entire
14:32 galaxies and help us understand the
14:34 broader story of cosmic Evolution every
14:37 large Galaxy that astronomers have
14:38 studied in detail seems to have a super
14:40 massive black hole at its core the Milky
14:43 Way for instance hosts a black hole
14:46 called Sagittarius A asterisk which has
14:49 a mass of about 4 million times that of
14:51 the sun other galaxies contain black
14:54 holes that are even larger the Galaxy
14:57 m87 for instance holds a super massive
15:00 black hole with a mass estimated to be
15:02 about 6 and a half billion times that of
15:04 the sun making it one of the most
15:06 massive black holes we've observed this
15:09 m87 asterisk black hole was also the
15:13 first ever black hole to be imaged in
15:16 2019 through data gathered from The
15:18 Event Horizon
15:20 telescope despite their incredible Mass
15:23 super massive black holes don't simply
15:25 sit at the centers of galaxies without
15:27 influence in instead they play an active
15:30 role in shaping the structures of the
15:31 galaxies around them one of the ways
15:34 they do this is by controlling the flow
15:36 of gas and stars in their neighborhoods
15:39 because of their intense gravitational
15:41 pull they can gather material from their
15:44 surroundings creating accretion discs
15:46 that can glow so brightly that they
15:48 outshine entire galaxies creating what
15:51 astronomers call Active Galactic nuclei
15:54 or
15:55 agns when viewed from far away an active
15:58 Galaxy looks like a single bright spot
16:00 with jets of radiation streaming from
16:02 its Center a sign that its super massive
16:05 black hole is actively consuming
16:09 material these jets are some of the most
16:12 powerful features associated with super
16:14 massive black holes as material falls
16:17 toward the black hole and heats up some
16:19 of it is expelled in two opposite
16:21 directions forming jets that travel at
16:24 nearly the speed of light these Jets can
16:27 extend for thousands of light years
16:29 pushing through the surrounding Galaxy
16:31 and even Beyond into Intergalactic space
16:35 the force of these Jets is so intense
16:37 that it can clear out gas from large
16:39 regions of the Galaxy halting Star
16:41 formation in those areas in this way
16:44 super massive black holes act as
16:46 Regulators of Galactic growth
16:49 controlling how much gas is available
16:51 for new stars and shaping the
16:53 distribution of stars within the
16:55 Galaxy some theories suggest that
16:58 galaxies and their Central black holes
16:59 grow together influencing each other
17:02 over billions of years when a galaxy is
17:05 Young and filled with gas it can produce
17:07 new stars at a rapid rate but as the
17:09 central black hole grows its Jets and
17:12 radiation start to heat up and blow away
17:14 the surrounding gas gradually slowing
17:17 down star formation this feedback loop
17:20 could be what allows galaxies to reach a
17:22 stable size with the black hole acting
17:24 as a kind of Galactic thermostat
17:27 preventing runaway growth
17:29 the exact process by which super massive
17:32 black holes form is still one of the
17:35 biggest mysteries in
17:37 astrophysics there are a few leading
17:39 theories but none have been fully
17:42 confirmed one idea is that these black
17:45 holes Grew From the merger of many
17:47 smaller black holes over time a process
17:50 that could have started in the very
17:51 early Universe when the first stars and
17:54 galaxies were forming another theory is
17:57 that super massive black holes formed
17:59 directly from massive clouds of gas that
18:01 collapsed under their own gravity
18:03 creating a black hole from scratch
18:05 without the need for a star this second
18:08 theory is particularly intriguing
18:10 because it suggests that some black
18:12 holes may have existed in the early
18:14 Universe even before the first Stars had
18:16 a chance to explode and create Stellar
18:19 black
18:20 holes by studying the light from distant
18:23 quazars galaxies with extremely bright
18:26 active nuclei we can see supermassive
18:28 black holes as they appeared billions of
18:31 years ago back when the universe was
18:33 young these quases allow us to trace the
18:36 history of black holes and galaxies
18:38 helping us understand how structures
18:40 formed and evolved over time some quasa
18:43 are so far away that the light we see
18:46 from them today began its Journey Across
18:48 the Universe when the universe itself
18:51 was only a fraction of its current
18:54 age Ultra massive black holes when super
18:57 massive just isn't enough when it comes
19:01 to black holes the word super massive
19:03 might seem like the ultimate descriptor
19:06 but in the cosmos there are a few black
19:08 holes that go beyond even that category
19:11 these rare extraordinary entities known
19:13 as ultramassive black holes stretch the
19:16 boundaries of what we understand about
19:18 Mass gravity and the formation of cosmic
19:21 structures ultramassive black holes are
19:24 defined as black holes with masses
19:26 exceeding 5 billion times that of our
19:28 sun and in some cases they reach 50
19:31 billion solar masses or more the scale
19:34 of these objects is almost unimaginable
19:37 and they challenge astronomers to
19:39 rethink not only the upper limits of
19:41 Black Hole Mass but also how such
19:43 behemoths could form in the first
19:45 place one of the first questions that
19:47 arise when considering ultramassive
19:49 black holes is how do they grow to such
19:52 astonishing
19:54 sizes for black holes of this Mass the
19:57 typical growth methods we know of
19:59 merging with other black holes or
20:01 gradually accumulating gas from the
20:03 Galaxy around them are not quite
20:05 sufficient to explain their sheer size
20:08 merges between black holes are rare and
20:11 occur over incredibly long time scales
20:14 so accumulating billions of solar masses
20:16 in this way would take far longer than
20:18 the age of the
20:19 universe similarly the material in a
20:22 galaxy is finite meaning that even if an
20:25 ultramassive black hole were to consume
20:27 gas and dust at a steady rate it still
20:29 wouldn't grow quickly enough to reach
20:31 these immense sizes within the lifespan
20:34 of the
20:34 universe some scientists theorize that
20:37 ultramassive black holes may have had a
20:40 head start in the early universe
20:43 according to one hypothesis these
20:45 colossal black holes may have started as
20:47 primordial black holes formed shortly
20:50 after the big bang when the universe was
20:53 much denser and more
20:55 chaotic if such primordial black holes
20:57 existed they could have grown rapidly by
21:00 consuming large amounts of gas in the
21:02 early Universe allowing them to reach
21:04 Ultra massive sizes within a relatively
21:07 short period another possibility is that
21:10 ultramassive black holes are the result
21:12 of extreme Galactic mergers when two
21:15 large galaxies Collide their Central
21:17 black holes often merge as well in rare
21:20 cases multiple mergers involving
21:23 galaxies that each contain super massive
21:25 black holes might lead to the creation
21:27 of an Ultra massive black hole these
21:30 events are rare and for an ultr massive
21:33 black hole to form the conditions would
21:35 need to be just right a series of Galaxy
21:38 collisions each one adding to the
21:40 central black hole's Mass might allow a
21:43 black hole to grow to an ultra massive
21:45 size over billions of years these Ultra
21:48 massive black holes would be found in
21:50 the largest galaxies and Galaxy clusters
21:53 where the environment is dense enough to
21:55 support such growth currently only a few
21:58 ultramassive black holes have been
22:00 detected and they tend to exist in the
22:02 most massive and densely populated
22:04 regions of the
22:06 universe one well-known example is the
22:08 black hole ton
22:10 618 located in a galaxy about 11 billion
22:14 light years from
22:15 Earth ton
22:17 618 is estimated to have a mass of
22:20 around 40.7 billion solar masses making
22:24 it one of the largest black holes ever
22:26 discovered since it is an active
22:28 Galactic nucleus it emits a great deal
22:31 of light so much so in fact that the
22:34 surrounding Galaxy is outshone by it and
22:36 hence is not visible to us it is 140
22:40 trillion times brighter than our sun
22:42 making it one of the brightest known
22:44 objects in the
22:45 universe we know that black holes feed
22:47 on surrounding matter pulling in gas and
22:50 dust as they grow however if a black
22:53 hole becomes too massive it can actually
22:55 begin to interfere with its own growth
22:58 the intense energy released as gas falls
23:00 into the black hole heats up and pushes
23:03 material away creating a feedback effect
23:07 this feedback can drive gas away from
23:08 the center of the Galaxy limiting the
23:11 amount of material that can fall into
23:12 the black hole this effect is so
23:15 powerful that it's often thought to be
23:17 responsible for limiting the size of
23:19 super massive black holes but Ultram
23:22 massive black holes suggest that somehow
23:25 a few black holes have managed to
23:27 overcome this limit and keep growing
23:29 defying the feedback process that
23:31 usually restricts their size the effects
23:35 of ultramassive black holes extend far
23:37 beyond their immediate
23:39 surroundings because of their Mass they
23:41 have an enormous gravitational reach
23:43 influencing Stars gas and even other
23:47 galaxies in Galaxy clusters the presence
23:50 of an ultramassive black hole at the
23:52 center can shape the behavior of nearby
23:56 galaxies the black hole's powerful
23:58 gravitational pull can hold the cluster
24:00 together preventing galaxies from
24:02 drifting away and keeping the cluster's
24:05 structure
24:06 intact ultramassive black holes also
24:09 produce massive Jets of energy similar
24:12 to super massive black holes but on an
24:14 even grander scale these Jets can extend
24:17 far beyond the Galaxy heating gas in the
24:20 surrounding area and affecting star
24:22 formation in neighboring
24:25 galaxies in this way ultramassive black
24:28 holes act as Cosmic Architects helping
24:32 to shape the structure and evolution of
24:34 Galaxy
24:35 clusters as we develop more powerful
24:37 telescopes and observatories our ability
24:40 to detect and study ultramassive black
24:43 holes is expected to improve future
24:46 missions may allow us to see these
24:48 Giants in Greater detail observing their
24:50 interactions with surrounding galaxies
24:52 and the effects of their immense
24:54 gravitational fields primordial black
24:56 holes ghosts from the dawn of the
25:00 universe unlike black holes that form
25:02 from the collapse of massive stars
25:04 primordial black holes are believed to
25:06 have formed in the earlier seconds of
25:08 the universe created directly from the
25:11 extreme conditions of the early
25:13 Cosmos at that time the universe was
25:16 incredibly compact with energy and
25:18 matter packed so tightly the tiny
25:20 fluctuations in density could have led
25:23 to areas with enough gravitational pull
25:25 to collapse in on themselves forming
25:28 black black holes these hypothetical
25:30 black holes known as primordial black
25:32 holes would have been born without
25:34 needing Stars existing as relics from a
25:37 period long before galaxies stars or
25:40 even atoms as we know them came into
25:43 being primordial black holes offer a
25:46 potential answer to some of the
25:47 universe's biggest
25:49 mysteries one of these Mysteries is the
25:51 origin of Dark Matter dark matter is a
25:54 form of matter that does not emit light
25:57 making it invisible and undetectable by
25:59 conventional
26:00 telescopes scientists know that dark
26:03 matter exists because its gravitational
26:05 influence can be seen affecting galaxies
26:07 and Galaxy
26:09 clusters without Dark Matter galaxies
26:11 would lack the mass needed to hold their
26:13 stars together and entire galaxy
26:15 clusters would lack the gravitational
26:17 glue needed to bind
26:18 them but despite Decades of study
26:21 scientists have yet to identify what
26:23 dark matter is made of some scientists
26:26 think primordial black holes might be a
26:27 solution to the Dark Matter mystery if a
26:30 large number of these black holes formed
26:32 in the early Universe they could be
26:34 scattered throughout the cosmos creating
26:36 a network of dark objects that exert
26:39 gravitational forces on visible matter
26:42 unlike the regular matter that makes up
26:44 stars planets and galaxies these
26:47 primordial black holes wouldn't emit any
26:49 light they would be in effect dark
26:52 objects matching the behavior of dark
26:55 matter if primordial black holes do
26:57 exist to make up a significant portion
26:59 of dark matter it would mean that dark
27:02 matter isn't made of exotic particles as
27:05 many scientists have previously assumed
27:07 but instead of ancient black holes left
27:09 over from the early Universe primordial
27:12 black holes would be much smaller than
27:14 the black holes we are used to thinking
27:16 about possibly with masses ranging from
27:19 that of a small asteroid to several
27:21 times the mass of the Sun unlike larger
27:25 black holes which influence their
27:27 surroundings by pulling in nearby gas
27:29 and dust smaller primordial black holes
27:32 would be nearly invisible interacting
27:35 only through their gravitational pull
27:37 this makes them challenging to observe
27:40 directly however there are some ways to
27:42 infer their presence for instance
27:45 scientists can search for tiny
27:47 distortions in the light from distant
27:49 Stars indicating the gravitational
27:51 influence of a small invisible black
27:54 hole passing in front of them this
27:57 technique known as gravitational
27:59 microlensing can reveal the presence of
28:01 compact objects that would otherwise go
28:04 unnoticed in the early Universe matter
28:07 was distributed more or less evenly but
28:10 slight irregularities eventually led to
28:12 the clumping of gas which formed the
28:15 first stars and galaxies the presence of
28:18 primordial black holes could have acted
28:20 as seeds for these structures providing
28:22 gravitational centers around which
28:24 matter could gather over time these
28:27 seeds would have attracted attracted
28:28 more gas and dust leading to the birth
28:30 of stars and
28:32 galaxies in this way primordial black
28:35 holes could have helped shape the
28:36 universe as we know it guiding the
28:39 formation of the first galaxies and
28:41 setting the stage for the Cosmic
28:43 Landscape we observe today without some
28:46 kind of seed to initiate the formation
28:48 of galaxies it's difficult to understand
28:51 how Cosmic structures could have emerged
28:53 as quickly as they did after the big
28:55 bang if primordial black holes were
28:58 present they would have acted as
28:59 catalysts providing the gravitational
29:02 anchor points needed to draw in matter
29:04 and accelerate the process of Galaxy
29:07 formation this Theory aligns with
29:09 observations showing that galaxies began
29:11 forming relatively soon after the big
29:14 bang suggesting that some kind of
29:16 gravitational scaffolding may have been
29:19 in place to guide their
29:21 development but while primordial black
29:23 holes offer fascinating explanations for
29:26 dark matter and Galaxy formation
29:28 their existence remains
29:30 hypothetical the search for primordial
29:33 black holes has led scientists to
29:35 explore a variety of methods from
29:37 gravitational wave detectors to Cosmic
29:39 microwave background studies
29:42 gravitational wave observatories like
29:44 ligo and Virgo which have already
29:46 detected merges between larger black
29:48 holes could potentially pick up signals
29:50 from merging primordial black holes as
29:53 well however such events would likely be
29:55 much rarer and fainter than those was
29:58 produced by larger black holes
30:00 scientists are also studying the cosmic
30:02 microwave background the faint glow of
30:05 radiation left over from The Big Bang if
30:08 primordial black holes were abundant in
30:11 the early Universe they could have left
30:13 subtle imprints on this background
30:16 radiation altering its structure in ways
30:18 that might still be detectable
30:21 today Rogue black holes wandering
30:24 dangers in the galactic void
30:28 Rogue black holes are not bound to any
30:30 specific location but move through the
30:33 Galaxy with little regard for what lies
30:35 in their path these objects though
30:38 potentially smaller in scale than their
30:40 super massive counterparts are
30:42 nevertheless capable of decimating
30:44 anything that crosses their
30:46 trajectory stars planets even entire
30:49 solar systems could face disruption if
30:51 one of these Rogue black holes were to
30:53 drift close enough Rogue black holes are
30:57 thought to form when a black hole gets
30:59 ejected from its home Galaxy or Star
31:01 cluster often as a result of powerful
31:04 gravitational
31:05 interactions one common cause of such an
31:08 ejection is the merger of two black
31:10 holes when two black holes come together
31:13 the final merger can release intense
31:15 gravitational waves that carry energy
31:18 away from the system this loss of energy
31:21 can send the resulting black hole
31:23 hurtling in a random Direction
31:25 effectively ejecting it from its
31:27 original location
31:29 another possible cause is when a black
31:31 hole forms from a star that is part of a
31:33 binary system if one star collapses into
31:36 a black hole while the other remains
31:38 intact the gravitational relationship
31:41 between the two might break sending the
31:43 black hole on a Wandering journey
31:45 through space once a black hole is on
31:48 the move its journey is governed by the
31:51 natural orbits and motions of galaxies
31:53 and star
31:54 clusters some Rogue black holes may
31:57 eventually find find new homes settling
31:59 into orbits around other stars or
32:02 entering different star clusters others
32:05 however May wander for billions of years
32:07 without encountering anything
32:09 substantial in the vastness of space
32:12 it's entirely possible for a rogue black
32:15 hole to travel undisturbed through
32:17 Interstellar space far from stars
32:19 planets or other celestial bodies but on
32:22 occasion a rogue black hole could stray
32:25 close to a solar system disrupting or
32:28 even destroying any planets or Stars
32:30 within range if a rogue black hole were
32:33 to enter our solar system the results
32:36 could be
32:37 devastating the black hole's gravity
32:39 would cause major disturbances
32:41 potentially altering the orbits of
32:43 planets or drawing gas and dust from
32:45 nearby stars for a black hole that's
32:48 only a few times the mass of our sun
32:50 such an encounter might start with
32:52 distant gravitational effects with the
32:54 outer planets experiencing changes in
32:57 their orbits
32:58 but as the black hole gets closer its
33:01 influence would grow stronger and
33:03 eventually it could reach a point where
33:05 planets are pulled from their paths
33:06 altogether or even swallowed by the
33:09 black hole for a system like ours a
33:11 rogue black hole would be a serious
33:13 threat even if it never came close
33:15 enough to Earth the disruption to the
33:18 gravitational balance would throw
33:20 planets asteroids and other bodies into
33:22 new unpredictable paths causing chaos on
33:25 a cosmic scale one of the the most
33:28 unsettling aspects of Rogue black holes
33:30 is their stealth unlike Stars which emit
33:33 light black holes are nearly invisible
33:35 they don't radiate light or other forms
33:37 of electromagnetic energy making them
33:40 difficult to detect unless they interact
33:42 with nearby matter the only way we'd
33:45 notice it is if it began to pull on the
33:47 system with its gravity causing stars or
33:50 planets to shift in their
33:51 orbits in cases where Rogue black holes
33:54 are actively consuming matter they may
33:57 become detected
33:58 as a black hole feeds on gas or dust
34:01 this material can form an accretion disc
34:03 around the black hole heating up and
34:05 emitting light as it spirals inward but
34:08 in the emptiness of interstellar space
34:11 where there is often little or no
34:12 material to consume a rogue black hole
34:15 could remain entirely undetectable until
34:18 it comes disturbingly close astronomers
34:21 believe there may be millions of Rogue
34:23 black holes scattered throughout our
34:24 galaxy but spotting them is challenging
34:28 some methods like gravitational
34:30 microlensing have been used to detect a
34:33 few potential Rogue black holes but it
34:35 requires precise alignment and timing
34:38 the vastness of space means that the
34:41 chances of a rogue black hole crossing
34:44 paths with a populated star system alow
34:47 but the possibility is there hyper
34:50 energetic quers unleashing black hole
34:53 Fury across the cosmos quers are among
34:57 the most powerful and luminous objects
34:59 in the universe so brilliant they can
35:01 outshine entire galaxies they are born
35:04 from super massive black holes that are
35:06 actively consuming enormous amounts of
35:08 material this Relentless consumption
35:11 fuels a process that transforms these
35:13 black holes into Cosmic beacons
35:16 Illuminating the dark depths of space
35:18 with intense energy the material falling
35:22 toward the black hole first forms an
35:24 accretion disc as this material spirals
35:27 inward it gets compressed and heated to
35:29 extreme temperatures releasing vast
35:31 amounts of light and other forms of
35:33 energy this energy is what makes quaza
35:36 so bright in some cases a single quaza
35:39 can shine hundreds of times brighter
35:41 than an entire galaxy allowing
35:44 astronomers to observe them from
35:46 billions of light years
35:47 away the intense brightness of quers
35:50 isn't just due to visible light they
35:53 emit Energy across nearly the entire
35:55 electromagnetic spectrum from radio
35:58 waves to X-rays and even gamma rays this
36:01 wide range of energy output makes quers
36:04 visible to different types of telescopes
36:06 each capturing different parts of the
36:08 radiation they emit this broad energy
36:11 range shows that quers are not just
36:14 bright but also incredibly energetic
36:17 releasing more power in a single second
36:19 than our sun will emit over billions of
36:21 years quazars often generate powerful
36:24 jets that shoot out from their poles
36:27 these these jets are made up of charged
36:29 particles accelerated to nearly the
36:30 speed of light and they can extend for
36:33 hundreds of thousands even millions of
36:36 light years beyond the host
36:38 Galaxy the energy carried by these Jets
36:41 interacts with gas dust and other
36:43 galaxies in the surrounding region
36:45 creating shock waves and influencing the
36:48 evolution of galaxies nearby the Jets
36:51 can be powerful enough to push material
36:53 out of the Galaxy halting Star formation
36:55 by removing the gas needed to form new
36:58 stars the Jets from aazar can also heat
37:01 up Intergalactic gas preventing it from
37:04 Cooling and collapsing to form stars in
37:07 This Way quazars can suppress star
37:09 formation not only in their own host
37:12 galaxies but also in nearby galaxies
37:15 effectively sterilizing parts of the
37:18 universe because they are so bright
37:20 quers can be observed across vast
37:23 distances allowing scientists to look
37:25 back billions of years in time the light
37:28 we see from distant quasa began its
37:30 Journey long before our sun or solar
37:32 system even existed providing a direct
37:34 window into the early
37:36 Universe by studying quasa at different
37:39 distances astronomers can trace the
37:41 evolution of galaxies and black holes
37:44 over Cosmic history piecing together how
37:46 the first black holes formed grew and
37:49 influenced their
37:51 surroundings while quers are mostly
37:53 observed in distant galaxies there was a
37:55 time when they were more common in the
37:57 universe IE in the early stages of the
37:59 universe galaxies were closer together
38:02 and full of gas creating the ideal
38:04 conditions for black holes to feed and
38:06 generate
38:07 quases over time as galaxies evolved and
38:11 their Central black holes consumed
38:12 nearby material quers became less common
38:16 giving way to quieter galaxies like our
38:18 own Milky Way today most quaz as we
38:21 observe are billions of light years away
38:24 meaning we're seeing them as they were
38:26 in the distant part past if a quaza were
38:29 to flare up in a galaxy relatively close
38:31 to ours the intense radiation could have
38:34 serious consequences for nearby star
38:36 systems potentially even affecting
38:39 planets the gamma rays and other high
38:41 energy radiation emitted by quers could
38:44 strip away atmospheres or disrupt the
38:46 chemical processes necessary for Life
38:49 fortunately most active quers are far
38:52 from our galaxy The amount of material
38:55 required to fuel a quazer is immense
38:57 raising questions about how such large
38:59 amounts of gas and dust accumulate and
39:02 feed the black hole over time the
39:05 physics of the Jets produced by quers
39:07 also remains an area of active research
39:10 as scientists try to understand how
39:12 particles are accelerated to such
39:14 extreme speeds and what role magnetic
39:17 fields play in the process quers serve
39:20 as powerful examples of how black holes
39:22 despite their name can be some of the
39:25 brightest and most dynamic objects in
39:27 the
39:28 universe Blazers when black holes Point
39:32 their Cosmic beams at
39:34 Earth blazars are a unique and extreme
39:37 type of active Galactic nucleus what
39:40 sets blazars apart is the alignment of
39:43 their powerful Jets which are directed
39:45 almost precisely toward Earth this
39:48 alignment makes bazars appear especially
39:51 bright to observers on Earth this direct
39:54 line of sight alignment allows us to see
39:56 details of their energetic processes
39:59 that are hidden in other
40:01 galaxies the intense brightness of
40:03 blazers comes from the super massive
40:05 black hole at their core which pulls in
40:08 massive amounts of gas and dust from the
40:10 Galaxy around it but it's the Jets
40:13 streaming from the poles of the black
40:15 hole that make blazar so
40:17 remarkable these jets are composed of
40:20 charged particles like electrons
40:22 accelerated to near the speed of light
40:25 by powerful magnetic fields Genera ated
40:27 by the black holes
40:29 spin as these Jets Point directly at
40:31 Earth they become concentrated and
40:34 Amplified creating what scientists call
40:36 a relativistic beaming
40:38 effect this effect is like shining a
40:41 flashlight directly into an observer's
40:43 eyes it makes the Blazer appear brighter
40:45 and more energetic than it would if the
40:47 jet were oriented away from us these
40:50 powerful Jets emit radiation across the
40:53 entire electromagnetic spectrum
40:55 producing waves of energy that can be
40:57 detected by various types of telescopes
41:00 including radio Optical and gamma ray
41:03 observatories the energy output of
41:05 blazers is so great that they can
41:07 fluctuate rapidly with bursts and flares
41:10 that vary in brightness from day to day
41:12 or even minute to minute these flares
41:15 are driven by turbulence and collisions
41:17 within the jet as particles slam into
41:19 each other and release
41:21 energy the cause of these eruptions is
41:23 still not entirely understood but they
41:26 likely involve sudden shifts in the
41:28 magnetic fields surrounding the black
41:29 hole leading to explosions of energy
41:32 that send powerful waves of radiation
41:34 toward
41:35 Earth the radiation emitted by Blazers
41:38 includes gamma rays the most energetic
41:41 form of light gamma rays are dangerous
41:44 because they have enough energy to
41:45 penetrate matter and disrupt atoms
41:48 breaking apart molecules and creating
41:50 harmful particles when blazars flare up
41:53 they send streams of gamma rays into
41:56 space if if Earth were close enough to
41:58 an active Blaze R the radiation could
42:00 have serious effects on our planet
42:02 stripping away parts of the atmosphere
42:04 or disrupting Life by interfering with
42:07 biological
42:09 processes fortunately the nearest known
42:11 Blazers are far enough away that their
42:13 gamma rays disperse and weaken long
42:15 before reaching us however studying the
42:19 impact of this intense radiation allows
42:21 scientists to understand the potential
42:23 hazards that similar processes could
42:26 pose if they occurred closer to home
42:29 blazars don't just emit light they also
42:32 send out high energy particles known as
42:35 cosmic rays these cosmic rays
42:38 accelerated to incredible speeds by the
42:40 magnetic fields in the Jets are some of
42:43 the fastest moving particles in the
42:45 universe when they reach Earth they
42:47 collide with particles in our atmosphere
42:50 creating Showers of secondary particles
42:52 that can be detected on the ground
42:55 cosmic rays from Blazers provide
42:57 valuable information about the
42:58 composition and behavior of the
43:00 Jets however cosmic rays are also a form
43:03 of radiation that in high doses can be
43:07 harmful the brightness and variability
43:09 of blazars make them ideal natural
43:12 Laboratories for studying high energy
43:14 physics helping researchers to refine
43:17 models of how black holes interact with
43:20 their
43:21 surroundings Event Horizon collisions
43:24 what happens when black holes merge
43:27 when two black holes come close enough
43:29 to each other they enter a cosmic dance
43:32 that will ultimately end in a dramatic
43:34 Collision these collisions between black
43:37 holes are among the most powerful events
43:39 in the universe releasing vast amounts
43:41 of energy in the form of gravitational
43:43 waves gravitational waves are ripples in
43:46 the very fabric of space and time
43:48 traveling outward like waves in a pond
43:51 the Collision of black holes an event of
43:54 such intense gravity twists and
43:56 stretches space itself as the two black
44:00 holes spiral toward each other they
44:02 accelerate and gain energy moving faster
44:05 and faster this process known as
44:08 inspiral is where most of the
44:10 gravitational waves are generated the
44:12 strength of these waves increases as the
44:15 black holes get closer and the frequency
44:17 of the Waves Rises these gravitational
44:21 waves carry information about the black
44:23 holes such as their masses spins and the
44:26 dist between them allowing scientists to
44:29 study the black holes
44:32 indirectly the waves travel across
44:34 billions of light years reaching Earth
44:36 with only a tiny fraction of their
44:38 original strength but sensitive
44:41 detectors like ligo and Virgo can pick
44:43 up these faint signals at first the two
44:47 black holes orbit each other at a
44:49 distance but as they spiral inward they
44:52 fall closer and closer and the
44:54 gravitational waves they emit grow more
44:56 intense
44:58 the closer they get the stronger their
45:00 gravitational fields merge distorting
45:03 SpaceTime more severely this rapid
45:06 acceleration creates an almost deafening
45:08 surge in gravitational waves an
45:10 indication that the two black holes are
45:12 on the verge of colliding at the moment
45:15 of impact they combine their masses into
45:18 a single larger black hole unleashing a
45:22 powerful burst of gravitational waves
45:24 that ripples Across the Universe
45:27 the final moment before the merger is
45:29 called the ringdown phase where the
45:32 single newly formed black hole releases
45:35 a last intense wave of gravitational
45:37 energy before settling
45:40 down the energy released during this
45:42 phase can be greater than the energy
45:44 emitted by all the stars in a galaxy
45:46 combined but it only lasts for a
45:48 fraction of a second this new larger
45:51 black hole is less massive than the
45:53 combined mass of the original two black
45:56 holes
45:57 this is because a small portion of their
45:59 combined mass is converted directly into
46:02 gravitational wave energy and released
46:04 into
46:05 space with gravitational wave astronomy
46:09 scientists have a new way to hear black
46:11 holes in action each Collision adds to
46:14 our knowledge of the universe confirming
46:16 Einstein's predictions about gravity and
46:18 SpaceTime and giving us clues about how
46:21 black holes form and grow as two black
46:24 holes Collide they bring with them their
46:26 individ idual spins an angular momentum
46:29 this means the merged black hole might
46:31 spin very rapidly creating one of the
46:33 fastest rotating objects in the universe
46:36 this High rotation speed can distort the
46:39 shape of the New Black Hole flattening
46:41 it slightly at the
46:42 poles some researchers believe that if
46:45 the merged black hole spins fast enough
46:48 it could even create Jets of particles
46:50 similar quers although this remains a
46:53 theoretical
46:55 idea the merging of black holes is a
46:57 truly chaotic process surrounding
47:00 material if there is any could be pulled
47:03 in and heated up by the intense
47:05 gravitational fields potentially
47:07 creating flashes of light or other
47:09 electromagnetic signals that scientists
47:12 could
47:13 detect however since black holes are
47:15 often found in areas with little gas or
47:18 dust these events are usually dark and
47:21 invisible except for their gravitational
47:24 waves gravitational waves from black
47:27 hole mergers have also taught us about
47:29 the size and distribution of black holes
47:31 in the universe when scientists detect
47:34 these waves they can measure the mass
47:36 and size of the colliding black holes
47:39 revealing patterns about how and where
47:41 black holes
47:42 form some black holes are much heavier
47:45 than others suggesting they may have
47:47 already merged with other black holes in
47:49 the past in dense environments such as
47:52 star clusters black holes could merge
47:55 repeatedly forming progressively larger
47:57 black holes over time these hierarchical
48:01 mergers create a cycle of growth
48:04 possibly contributing to the formation
48:05 of super massive black holes found at
48:07 the centers of galaxies when two black
48:10 holes Collide their event Horizons
48:12 stretch and merge creating a new larger
48:15 Event Horizon scientists are still
48:17 studying what happens at this boundary
48:19 as the Collision creates an incredibly
48:21 complex and turbulent area of SpaceTime
48:24 that is difficult to understand
48:26 According to some theories this surface
48:29 where the two event Horizons meet might
48:32 briefly create intense gravitational
48:34 effects possibly even affecting the way
48:36 gravitational waves are emitted some
48:39 theories suggest that if two black holes
48:41 of extreme Mass were to collide they
48:44 could briefly create a naked
48:46 Singularity an area where gravity
48:48 becomes infinitely strong without the
48:50 protection of an event
48:53 horizon The elusive recoiling black
48:56 holes
48:57 when black holes are ejected from
49:00 galaxies sometimes when two black holes
49:03 merge the force of their Collision is so
49:05 intense that the newly formed black hole
49:08 doesn't stay put in its original
49:10 location instead it can be kicked out of
49:13 the center of the Galaxy it once
49:14 belonged to sent hurtling through space
49:17 like a cosmic Wanderer these are called
49:20 recoiling black holes to picture it
49:24 imagine two massive whirlpools in the
49:26 ocean merging emerging creating such a
49:28 strong surge of energy that the new
49:30 larger Whirlpool is flung
49:32 outward that's essentially what happens
49:34 to recoiling black holes when black
49:37 holes merge they release an intense
49:39 burst of gravitational waves but if the
49:42 black holes are of different sizes or if
49:44 they're spinning in different directions
49:46 the gravitational waves they emit can
49:49 become uneven it's like a rocket
49:52 blasting off when the forces acting on
49:54 it aren't balanced it gets pushed in One
49:58 Direction in the case of merging black
50:00 holes the imbalance in gravitational
50:03 waves creates a powerful kick sending
50:06 the new black hole off at incredible
50:09 speeds this kick can be so strong that
50:12 it overcomes the gravitational pull of
50:14 the Galaxy ejecting the black hole into
50:17 Intergalactic space evidence for
50:20 recoiling black holes comes from
50:22 observations of the centers of galaxies
50:24 where a super massive black hole should
50:26 be present yet appears to be missing in
50:29 these cases astronomers speculate that
50:32 the black hole was ejected after a
50:34 merger in a few cases scientists have
50:37 spotted strange luminous Trails thought
50:39 to be recoiling black holes pulling
50:42 along a stream of gas or stars as they
50:44 leave their galaxies behind depending on
50:47 the strength of the gravitational wave
50:49 kick a recoiling black hole could travel
50:52 through space at speeds of thousands of
50:54 kilomet per second this velocity is fast
50:58 enough to escape not only the core of
51:00 the Galaxy but even its outer regions
51:03 once it escapes the black hole is left
51:05 to drift through Intergalactic space
51:08 there the recoiling black hole would
51:10 likely continue to pull in any gas or
51:12 dust it encounters but without the rich
51:15 environment of a galaxy it would appear
51:17 mostly invisible nearly impossible to
51:20 detect
51:21 directly without a central black hole
51:24 the Galaxy loses a powerful gravit
51:26 ational anchor this can lead to changes
51:29 in the movement of stars as well as the
51:31 distribution of gas and dust ultimately
51:34 affecting the Galaxy's future shape and
51:37 development in some cases the Galaxy may
51:40 eventually attract another black hole
51:42 but until then it may lack the typical
51:45 features of a galaxy with an active
51:47 Central super massive black hole the
51:50 Rarity of these events means that
51:52 recoiling black holes are difficult to
51:55 study and so far astronomers have only
51:58 indirect evidence of their
51:59 existence what happens to these black
52:02 holes over long stretches of time do
52:04 they eventually slow down or settle into
52:06 new locations could they influence the
52:09 formation of new galaxies or will they
52:12 remain as isolated points of intense
52:14 gravity in The Emptiness of space x-ray
52:17 beacons of Doom black holes as powerful
52:20 Cosmic
52:21 lighthouses some black holes become
52:23 powerful sources of X-ray emissions
52:26 Illuminating ating the dark Cosmos with
52:27 radiation that travels across vast
52:30 distances these x-ray beacons can be
52:33 incredibly intense providing a way for
52:35 astronomers to detect black holes that
52:38 would otherwise be
52:39 invisible these x-rays are produced when
52:42 friction and immense pressure within the
52:43 accretion disc generates extreme heat
52:47 sometimes reaching millions of degrees
52:50 at these temperatures the material emits
52:52 x-rays which stream outward from the
52:54 black hole and into space
52:57 one of the most famous examples of a
52:58 black hole x-ray source is signis X1 a
53:02 stellar Mass black hole about 7,200
53:04 light years from Earth in the
53:06 constellation signus signus X1 is locked
53:10 in a gravitational dance with a nearby
53:12 star drawing gas from its companion into
53:15 an accretion disc the disc heats up and
53:18 produces an intense stream of x-rays
53:20 that astronomers have been observing
53:22 since the
53:23 1960s in binary systems where a black
53:26 hole and a star orbit each other the
53:29 intense x-rays can strip material away
53:31 from the companion star altering its
53:34 Evolution over time this radiation can
53:37 erode the outer layers of the star
53:40 disrupting its surface and possibly
53:42 changing its Fate The Star May age
53:45 faster or evolve differently than it
53:48 would have without the influence of the
53:50 black hool's radiation creating a
53:52 strange symbiotic relationship where the
53:55 black holes present presence shapes the
53:57 life of its neighboring
53:59 star for any nearby planets the intense
54:03 x-rays from a black hole would be
54:05 devastating x-rays are a form of high
54:08 energy radiation and prolonged exposure
54:11 can strip away planetary atmospheres
54:13 especially if the planet orbits close to
54:15 the black hole the radiation could also
54:18 interfere with any chemical process is
54:20 essential to life even if a planet were
54:23 located at a safer distance the occasion
54:26 flares from the black hole accretion
54:28 disc could create bursts of radiation
54:31 strong enough to impact any organisms
54:33 living on its surface x-ray emissions
54:36 from black holes can also be detected
54:38 over large Cosmic
54:40 distances super massive black holes
54:43 often produce intense x-rays which allow
54:46 astronomers to detect and study them
54:48 from billions of light years away
54:50 quazars emit vast amounts of energy
54:53 across the electromagnetic spectrum
54:55 including x-ray
54:57 this radiation allows astronomers to
54:59 detect quers in distant galaxies serving
55:03 as a kind of cosmic Lighthouse that
55:05 illuminates the far reaches of space
55:08 x-ray observations of black holes have
55:10 opened up new ways to study these Jets
55:13 and understand their effects in many
55:16 ways x-ray emissions provide a snapshot
55:19 of the activity happening near the black
55:21 hole capturing the release of energy and
55:24 its journey through space
55:26 this gives scientists a valuable window
55:29 into the high energy physics of black
55:31 holes and the forces that shape
55:34 galaxies by studying x-rays scientists
55:37 can learn about the size mass and even
55:40 the spin of a black hole the intensity
55:43 and variability of the X-ray emissions
55:45 can reveal details about the black
55:47 hole's accretion disc the amount of
55:49 matter it's consuming and the behavior
55:51 of the surrounding gas in some cases
55:54 astronomers can detect qu I periodic
55:57 oscillations or qpos in the X-ray
56:00 emissions which are thought to be caused
56:02 by matter orbiting close to the black
56:03 hole's Event Horizon x-ray astronomy has
56:07 grown tremendously in recent decades
56:09 allowing scientists to uncover more
56:11 about the nature of black holes
56:14 observatories like the Chandra x-ray
56:16 Observatory and the European space
56:18 agency's xmm Newton telescope have
56:20 played a crucial role in advancing our
56:23 understanding of these Cosmic phenomena
56:25 with the abil AB ility to detect x-ray
56:27 emissions across different wavelengths
56:30 these telescopes allow astronomers to
56:32 explore black holes in Greater detail
56:34 uncovering Mysteries that were once
56:36 beyond our reach despite the dangers
56:40 associated with x-ray emissions from
56:42 black holes these signals are essential
56:44 for advancing our knowledge of the
56:47 universe without x-rays many black holes
56:50 would remain hidden and we would know
56:52 far less about their role in Cosmic
56:55 evolution
56:57 super massive Cosmic cannibals black
57:00 holes devouring star clusters in the
57:03 heart of many galaxies black holes go
57:06 beyond the act of drawing in single
57:08 Stars they devour entire star clusters
57:12 these super massive black holes millions
57:15 or even billions of times the mass of
57:17 the Sun can destabilize the regions
57:20 around them pulling in not just stars
57:23 but dense clusters of them bound
57:25 together by their own Mutual gravity
57:28 this is a wholesale consumption of
57:29 tightly packed groups of stars each
57:32 cluster potentially housing thousands or
57:35 even millions of
57:36 suns when a black hole encounters a star
57:39 cluster the Stars inside are immediately
57:42 at risk of being drawn into the black
57:43 hole's gravitational
57:45 influence because these clusters are
57:47 usually tightly bound with stars
57:50 orbiting close to each other the
57:52 disruption of one part of the cluster
57:54 can lead to a cascading effect
57:57 stars in the cluster move in complex
57:59 orbits often interacting with each other
58:02 as they feel the gravitational force of
58:04 the black hole when a cluster is close
58:06 enough to a super massive black hole the
58:09 gravitational pull on the nearest stars
58:11 in the cluster become so powerful that
58:14 they begin to spiral
58:16 inward as these Stars approach the black
58:18 hole they can be torn apart by tidal
58:21 forces especially if they get too close
58:24 to the event horizon this this process
58:27 known as tidal disruption occurs when a
58:29 star is pulled so strongly by the black
58:31 hole that it stretches elongating as it
58:34 spirals closer eventually the star can
58:37 be shredded entirely with its gas and
58:40 material spiraling down into the black
58:42 Hool accretion disc this results in a
58:45 burst of energy releasing intense X-rays
58:48 and other forms of radiation which can
58:50 be detected from millions of light years
58:52 away the cluster meanwhile continues to
58:55 lose Stars destabilized by the loss of
58:58 its members and gradually falling apart
59:01 over time what was once a tight
59:03 collection of stars might be spread out
59:06 leaving only traces of its original
59:08 structure the process of devouring star
59:10 clusters has a ripple effect on the
59:12 larger Galaxy for instance the motion of
59:15 stars near the Galactic Center becomes
59:17 influenced by the black hole's
59:19 gravitational pull causing more stars to
59:21 slowly spiral
59:23 inward as clusters of stars are consumed
59:25 or broken apart the surrounding Galaxy
59:28 can undergo changes gas and dust clouds
59:31 near the black hole get heated and
59:32 agitated by the radiation released
59:34 during these tidal disruptions
59:37 preventing them from Cooling and
59:38 collapsing to form new stars the areas
59:42 near the black hole become regions of
59:44 star death rather than star birth and
59:47 over time the galactic center may appear
59:50 depleted of young
59:52 Stars observations of many galaxies show
59:56 evidence of clusters and stars either
59:58 spiraling into the black hole or having
60:01 already been absorbed for example in the
60:04 Milky Way scientists have found stars
60:07 that seem to be on courses directly
60:08 influenced by Sagittarius A
60:11 asterisk some of these stars are known
60:13 as s Stars a collection of stars
60:16 orbiting very close to the galactic
60:18 center their high speeds and unusual
60:21 orbits suggest that many of them were
60:23 once part of larger groups or clusters
60:26 but was scattered due to the
60:27 gravitational interactions around
60:28 Sagittarius A
60:30 asterisk these Stars might represent
60:32 remnants of clusters that once ventured
60:35 too close to the black hole with many of
60:37 their companions already consumed
60:40 galaxies with larger more active black
60:42 holes can have even more dramatic
60:44 effects on their surroundings in some
60:46 galaxies there are signs that super
60:48 massive black holes have devoured
60:50 multiple clusters leaving evidence in
60:53 the form of high energy Jets and x-rays
60:56 over billions of years black holes that
60:59 continue to feed on clusters can grow to
61:01 monstrous sizes especially if the
61:04 Clusters contain dense groups of stars
61:06 that are readily
61:07 available by devouring clusters they are
61:10 able to grow at a rate faster than by
61:13 simply consuming individual
61:15 Stars this means that a galaxy with many
61:18 Dense Star clusters could in theory have
61:20 a central black hole that grows faster
61:23 and becomes more massive than those in
61:25 galaxies with fewer clusters available
61:27 for
61:28 consumption as the black hole grows and
61:30 absorbs more material it continues to
61:33 exert a stronger gravitational influence
61:36 further destabilizing the region around
61:38 it star clusters especially those that
61:41 stray into its reach find it nearly
61:44 impossible to remain intact the process
61:47 accelerates as more stars are drawn into
61:50 the black hole's pool each cluster
61:53 represents a rich source of mass for the
61:55 black hole allowing it to expand and
61:57 exert even more control over its
62:00 surroundings when a cluster is absorbed
62:02 the material that spirals into the black
62:04 hole releases more energy than the
62:06 entire Milky Way generates in a year
62:09 this energy can radiate outward creating
62:12 powerful jets that blast through the
62:14 Galaxy these Jets composed of high
62:17 energy particles can travel for hundreds
62:19 of thousands of light years piercing
62:21 through the Galaxy's layers and even
62:23 affecting neighboring galaxies in some
62:26 cases they collide with nearby gas
62:28 clouds compressing them and possibly
62:30 triggering bursts of star formation far
62:33 from the blackhole's
62:35 location black hole Stars theories on
62:38 stars made of pure black hole
62:41 matter in the speculative reaches of
62:43 astrophysics there exist these
62:45 hypothetical objects that are among the
62:47 strangest Concepts that scientists have
62:49 proposed black hole
62:53 Stars black hole Stars if they exist
62:55 would be objects so massive and dense
62:58 that they Verge on becoming black holes
63:00 themselves or perhaps house a black hole
63:02 at their core they represent a fusion of
63:05 two of the universe's most powerful and
63:07 mysterious forces the life of stars and
63:10 the profound gravitational pull of black
63:13 holes stars shine by converting hydrogen
63:16 into helium through nuclear fusion a
63:18 process that produces the energy and
63:20 light we see this Fusion process
63:23 generates immense pressure that
63:24 counteracts the force of GRA gravityy
63:26 keeping the star from collapsing under
63:28 its own weight in large Stars this
63:32 Fusion continues with heavier and
63:33 heavier elements until it reaches iron
63:36 after which Fusion no longer provides
63:38 energy for the most massive stars this
63:42 signals the end of their stable lives
63:44 leading to a collapse and often a
63:47 violent explosion called a
63:49 supernova if the remnants of the
63:51 collapsed star are dense enough they
63:54 form a black hole
63:56 one Theory however suggests that in the
63:58 early Universe before galaxies and
64:01 typical stars formed there may have
64:03 existed Stars so massive that they
64:05 behave differently from anything seen
64:07 today these primordial black ho Stars
64:10 would have been hundreds of times larger
64:12 than the largest Stars we know of
64:14 containing enough Mass to prevent them
64:16 from collapsing immediately under their
64:18 own gravity instead of collapsing
64:20 directly into a black hole these Stars
64:23 could have sustained themselves for a
64:24 Time exist existing in a quasi stable
64:27 state where their intense gravity
64:29 balanced against some form of pressure
64:31 possibly radiation or the mysterious
64:34 effects associated with black hole
64:37 formation one of the ideas behind black
64:39 hole stars is that they could form a
64:41 kind of shell around a black hole with
64:43 the black hole itself residing at the
64:45 core in this scenario the black hole
64:48 does not instantly consume the entire
64:50 star but rather feeds on it gradually
64:53 from
64:53 within as the black hole the center
64:56 pulls in material it would generate
64:58 incredible amounts of energy potentially
65:01 creating intense radiation pressure that
65:03 pushes outward and stabilizes the outer
65:05 layers of the
65:07 star this pushpull Dynamic could
65:10 theoretically allow the outer parts of
65:12 the star to exist for a time even as the
65:15 core continues to collapse into the
65:17 black hole this balance would delay the
65:20 total collapse enabling the star to
65:22 exist in a unique almost Lial State
65:25 between a star in a black hole another
65:27 idea is that in some cases black hole
65:30 Stars might form without a black hole at
65:32 their core instead reaching a state
65:34 where they are on the edge of collapse
65:36 but held in check by their own massive
65:38 energy output these Stars would be
65:41 nearly incomprehensible in size and
65:44 brightness their gravity so powerful
65:47 that they might bend light and distort
65:49 the space around them such Stars would
65:52 essentially be ticking time bombs
65:54 teetering on the bridge rink of collapse
65:57 over time they would lose Mass through
65:59 powerful Stellar winds and once they
66:02 reached a certain point they would
66:04 collapse into black
66:06 holes if black hole stars did exist in
66:09 the early Universe they might have been
66:11 some of the first objects to collapse
66:14 and form black
66:15 holes they could have served as
66:17 precursors to the super massive black
66:19 holes we find at the centers of galaxies
66:22 today since the early Universe was
66:25 filled with vast clouds of gas and dust
66:28 conditions were different from those we
66:29 see today Stars could have grown to
66:32 immense sizes because there were not yet
66:34 competing forces from other galaxies
66:37 stars or other structures that would
66:40 limit their growth these early black
66:43 hole stars or at least the black holes
66:45 they created might have influenced the
66:47 formation of
66:49 galaxies by injecting energy and
66:51 gravitational pull into the cosmic
66:53 fabric these early Giants could have
66:55 attracted surrounding matter helping to
66:58 shape the early galaxies the
67:00 gravitational influence of such massive
67:02 objects would have drawn in gas and dust
67:05 perhaps serving as seeds around which
67:08 galaxies eventually
67:10 formed in the unlikely event that a
67:12 black hole star did still exist
67:14 somewhere in the universe today it would
67:17 be one of the most extreme objects
67:19 imaginable such a star would emit
67:22 radiation and energy on a colossal scale
67:25 with a enough gravity to warp space and
67:27 time around it the Regions near the
67:29 star's surface would be incredibly hot
67:31 possibly glowing with intense
67:33 radiation in this way a black hole star
67:36 would resemble a small quazar a powerful
67:39 energy source fueled by a black hole but
67:41 with an entire Stars worth of mass still
67:44 surrounding it in theory studying the
67:47 remnants of these black hole Stars if
67:49 any still exist or left any traces could
67:52 reveal clues about the conditions of the
67:55 early
67:56 Universe observing them however would be
67:59 challenging due to their possible
68:01 Rarity some scientists are looking for
68:04 ways to detect ancient black holes from
68:06 the early universe as these might offer
68:08 indirect evidence that black hole Stars
68:11 once existed the search involves
68:14 examining the gravitational effects on
68:16 surrounding space and the background
68:18 radiation left over from The Big Bang
68:20 looking for any signs that could suggest
68:22 the presence of such extraordinary
68:24 objects
68:26 white holes the theoretical mirror
68:29 images of black
68:30 holes while black holes are regions
68:33 where everything can fall in but nothing
68:35 can escape white holes would be regions
68:38 where nothing could ever enter yet
68:40 matter and energy could emerge out of
68:42 them they're like Cosmic one-way doors
68:45 but with the direction reversed no
68:47 information or matter can go in but
68:49 information and matter could come out
68:52 while black holes trap everything within
68:54 them once it crosses is the Event
68:56 Horizon white hols would have a sort of
68:58 reverse Event Horizon preventing
69:01 anything from getting too close or
69:03 entering but despite the appealing idea
69:05 of white holes as the cosmic
69:07 counterparts to black holes they remain
69:09 entirely
69:11 theoretical no one has ever observed one
69:14 and the concept is primarily a solution
69:16 that comes out of the mathematics of
69:17 Einstein's theory of general
69:20 relativity the idea of white holes arose
69:22 when scientists looked at the equations
69:24 describing black holes and began asking
69:27 questions about symmetry in the universe
69:30 according to general relativity the
69:32 equations that describe black holes can
69:34 have a kind of mathematical mirror image
69:37 that leads to the possibility of a white
69:39 hole if a black hole represents a place
69:42 where SpaceTime curves infinitely inward
69:44 a white hole represents SpaceTime
69:46 curving infinitely outward in other
69:49 words if black holes are cosmic vacuums
69:51 that draw in everything white holes
69:53 would be like Cosmic fountains ejecting
69:55 matter and energy out into space while
69:59 these equations seem valid
70:00 mathematically they also create
70:02 conditions that sound almost impossible
70:04 to visualize in a physical sense one
70:07 idea about white holes is that they
70:09 could theoretically exist as the end
70:11 points of black holes this concept comes
70:14 from the idea of black hole evaporation
70:17 or Hawking radiation which was proposed
70:19 by Steven Hawking in his groundbreaking
70:22 work Hawking showed that black holes
70:24 could emit radiation ation and over very
70:27 long time scales gradually lose mass and
70:30 even evaporate completely some
70:33 scientists have speculated that if a
70:34 black hole eventually loses all its mass
70:37 it could transform into a white hole in
70:40 this way a white hole could be the final
70:42 form of a black hole after it has shed
70:44 all of its mass and
70:46 radiation according to this idea the
70:48 information and energy that fell into
70:51 the black hole might eventually be
70:52 released as a white hole this would be a
70:56 solution to what physicists call the
70:58 information Paradox the puzzle of what
71:01 happens to information that enters a
71:03 black
71:04 hole could a white hole be the
71:06 universe's way of preserving and
71:08 releasing that
71:10 information another theory proposes that
71:13 white holes could be connected to black
71:15 holes through a sort of cosmic Bridge a
71:17 tunnel called a wormhole a wormhole is
71:20 another hypothetical structure in
71:22 SpaceTime that has often been featured
71:24 in science fiction
71:26 it's imagined as a shortcut or tunnel
71:28 between two separate points in space in
71:31 the case of black holes and white holes
71:34 some physicists have speculated that
71:36 they might be connected by a wormhole
71:39 allowing matter and information to flow
71:41 from one part of the universe to another
71:43 through this tunnel in this model the
71:46 black hole would act as the entrance
71:48 drawing matter in while the white hole
71:51 would act as the exit spewing that
71:53 matter out into a different Loc ation in
71:55 space or time while wormholes are
71:58 theoretically possible within the
72:00 framework of general relativity they
72:02 would require forms of exotic matter to
72:04 keep them stable exotic matter is a type
72:07 of hypothetical material with negative
72:09 energy or negative Mass which hasn't
72:11 been observed in the universe this makes
72:14 wormholes and by extension any direct
72:16 link between black holes and white holes
72:18 a theoretical concept white holes as
72:22 hypothetical objects raise a lot of
72:24 questions
72:25 for example if a white hole can't let
72:28 anything enter it what happens to the
72:30 matter and energy it might release would
72:33 it drift off into the universe in a
72:35 specific direction or would it stay
72:37 confined near the white hole in some
72:39 kind of reversed gravitational field the
72:42 mathematics of white holes doesn't
72:44 provide clear answers to these questions
72:46 Additionally the notion of a one-way
72:49 exit seems to contradict the way gravity
72:51 Works elsewhere in the universe since
72:54 gravity pulls objects together it seems
72:56 odd to imagine an object like a white
72:58 hole that would actively repel anything
73:01 that got near it in a universe dominated
73:04 by forces that pull things together a
73:07 structure that pushes everything away
73:08 feels out of
73:10 place some scientists have suggested
73:13 that white holes might actually be
73:14 responsible for some of the unexplained
73:16 phenomena we observe in the cosmos for
73:20 example the rapid bursts of energy
73:22 observed in gamma ray bursts some of the
73:24 most power ful explosions we see in the
73:26 universe are still not fully
73:29 understood a small number of physicists
73:31 have proposed that these events could be
73:33 white holes briefly switching on and
73:36 releasing a surge of energy before
73:38 quickly disappearing again according to
73:41 this Theory a white hole might form for
73:43 a fraction of a second emit a powerful
73:45 burst of energy and then collapse or
73:48 reclose some have even wondered if white
73:51 holes could explain the origin of our
73:53 universe itself
73:55 the Big Bang which created the universe
73:57 as we know it was an event of enormous
73:59 energy release from a single
74:02 point while the Big Bang isn't a white
74:04 hole in the traditional sense some
74:06 scientists have toyed with the idea that
74:08 it might resemble a white hole in the
74:10 way it expels matter and energy outward
74:13 in this view what we experience as space
74:16 expanding could be the effect of a white
74:18 hole injecting all matter and energy
74:20 into
74:23 existence Quant mechanical black holes
74:26 exploring the possibility of Micro
74:29 Monsters when we think of black holes we
74:31 picture enormous objects formed by
74:33 collapsing stars or found at the centers
74:36 of galaxies their gravitational pull so
74:39 intense that they shape whole regions of
74:41 space but some scientists believe black
74:44 holes might exist on a much smaller
74:46 scale at the level of particles where
74:49 they could be as Tiny as
74:51 atoms these hypothetical quantum
74:53 mechanical black holes or micro black
74:56 holes would form through different
74:58 processes than their larger counterparts
75:01 and though they're invisible to the eye
75:04 they might hold secrets that could
75:05 change our understanding of
75:08 physics in quantum mechanics particles
75:11 and energy can behave unpredictably
75:13 appearing and disappearing or even
75:15 existing in multiple places at once some
75:19 scientists think that under the right
75:20 conditions this unpredictability could
75:23 lead to the formation of tiny black
75:24 holes
75:25 especially at extremely high energies
75:27 from intense particle collisions or
75:30 perhaps even the extreme conditions of
75:32 the early Universe right after the big
75:34 bang the Large Hadron Collider or LHC
75:38 the world's most powerful particle
75:40 accelerator has been at the center of
75:42 many discussions about quantum
75:44 mechanical black holes when it smashes
75:47 particles together at near light speeds
75:49 it creates a burst of energy that mimics
75:52 conditions thought to have existed just
75:54 after the big bang H some scientists
75:57 hoped that these high energy collisions
75:59 might produce tiny black holes revealing
76:02 clues about how the universe looked in
76:04 its first moments if such black holes
76:06 did appear they would be incredibly
76:09 small maybe just a fraction of the size
76:11 of a proton they would exist only
76:14 briefly before evaporating disappearing
76:16 in a burst of Hawking radiation almost
76:19 as soon as they formed for large black
76:21 holes this process is incredibly slow so
76:25 slow that it would take longer than the
76:27 current age of the universe for them to
76:29 evaporate completely but for a tiny
76:31 black hole the process would happen much
76:33 more quickly a micro black hole might
76:36 only last for a fraction of a second
76:38 before Vanishing in a flash of radiation
76:40 taking any trace of its existence with
76:42 it one possibility that these tiny black
76:45 holes might point to is the existence of
76:48 extra Dimensions beyond the three we
76:50 know some theories like string theory
76:54 suggest that they might be hidden
76:55 dimensions of space that we can't
76:57 directly observe these extra Dimensions
77:00 could help explain the existence of
77:02 micro black holes as their formation
77:04 might depend on the way gravity Works in
77:07 these unseen Dimensions if we ever
77:09 detect a micro black hole it could be a
77:12 signal that the Universe has more
77:14 Dimensions than we currently understand
77:17 opening up a new frontier in physics
77:20 quantum mechanical black holes might
77:22 also help us solve one of the biggest m
77:24 iies in science the unification of
77:27 gravity and quantum
77:29 mechanics right now we have two major
77:32 theories that explain how the universe
77:35 works Einstein's theory of general
77:38 relativity describes gravity and works
77:40 well for large objects like planets and
77:43 stars quantum mechanics meanwhile
77:45 explains the behavior of particles at
77:47 the smallest
77:49 scales but when we try to combine these
77:51 two theories they Clash black ho holes
77:55 might be the key to bridging this Gap a
77:57 micro black hole would be a tiny object
78:00 with incredibly strong gravity merging
78:03 the worlds of quantum mechanics and
78:05 general relativity in a way we've never
78:07 seen studying these Quantum black holes
78:10 could help us find a single unified
78:12 theory that explains everything from the
78:15 largest galaxies to the smallest
78:17 particles some scientists believe that
78:20 these tiny black holes wouldn't be
78:22 dangerous to us as they would evaporate
78:25 so quickly that they'd barely interact
78:27 with their
78:28 surroundings but others wonder if under
78:30 certain conditions a micro black hole
78:33 could stick around for longer than
78:35 expected in that case it might start
78:38 pulling in particles from its
78:39 surroundings growing bit by bit if one
78:42 of these black holes somehow grew large
78:44 enough it could eventually reach a point
78:46 where it acted like a traditional black
78:48 hole with an event horizon and an
78:51 inescapable gravitational pull although
78:54 the chances of this happening are
78:56 thought to be very low in our everyday
78:59 world where matter is spread out and
79:01 particles are tiny a micro black hole
79:03 would struggle to grow even if it had an
79:06 extended
79:07 lifespan however this possibility has
79:09 captured the imagination of scientists
79:12 and the public alike sparking
79:14 imaginations about Micro Monsters That
79:17 Could one day roam free from the quantum
79:22 world time dilation and the Ed edge of
79:25 reality how black holes warp time in our
79:28 familiar world time moves at a constant
79:31 rate seconds tick by with comforting
79:33 regularity an even Rhythm marking the
79:36 steady passage of time yet near a black
79:39 hole this Rhythm becomes warped and
79:41 twisted the intense gravity of these
79:43 Cosmic giants has the power to stretch
79:45 and slow time itself creating a surreal
79:48 experience for anything or anyone
79:50 approaching the black hole this strange
79:53 effect is called time dilation a
79:56 consequence of Albert Einstein's theory
79:58 of relativity which tells us that time
80:00 doesn't flow at the same rate everywhere
80:03 it can be altered by both gravity and
80:06 speed as an object approaches a black
80:09 hole it begins to feel the effects of
80:11 time dilation let's imagine an astronaut
80:15 on a journey toward a black hole while a
80:17 second astronaut watches from a safe
80:19 distance far enough away that they don't
80:21 feel the black hole's gravity as
80:23 intensely
80:25 as the first astronaut moves closer to
80:27 the black hole the strong gravitational
80:30 field begins to slow down time relative
80:32 to the distant Observer to the second
80:35 astronaut watching from a distance it
80:37 would seem as if the first astronaut
80:39 were moving in slow motion every
80:41 movement every gesture would appear
80:43 stretched out almost Frozen but for the
80:47 astronaut moving toward the black hole
80:49 time would feel completely normal they
80:52 would experience no change in their
80:53 perception of time passing ing they'd
80:55 still think and move at their usual Pace
80:58 unaware of the slow motion effect seen
81:00 by The
81:01 Observer this phenomenon grows more
81:04 extreme the closer the astronaut gets to
81:06 the event
81:07 horizon at this Edge the time dilation
81:10 effect becomes so powerful that to an
81:13 outside Observer it would appear as if
81:15 the astronaut were almost completely
81:17 Frozen in Time suspended just above the
81:20 Event Horizon minutes would pass then
81:23 hours then years
81:25 and still the astronaut would seem
81:27 trapped in that moment barely moving as
81:30 though caught in a sort of
81:31 three-dimensional holographic
81:34 photograph for the astronaut approaching
81:36 the black hole this experience is very
81:39 different they would continue moving
81:42 forward crossing the Event Horizon
81:44 without realizing they appeared Frozen
81:46 to any distant
81:48 observers if they looked back at the
81:50 universe behind them they'd see
81:53 something equally strange
81:55 all of the light from the Stars galaxies
81:57 and even the distant planets would
81:59 appear to be speeding up as if the rest
82:02 of the universe were racing forward in
82:05 time this is the effect of gravitational
82:08 time dilation in reverse while those far
82:11 from the black hole see the astronaut
82:13 slowing down the astronaut experiences
82:15 the universe speeding up everything
82:18 outside the black hole's influence would
82:20 seem to accelerate racing through epochs
82:23 with stars of appearing to age and die
82:25 in mere
82:26 moments this time dilation effect near a
82:29 black hole can be so extreme that
82:31 theoretically an observer falling into a
82:34 massive enough black hole might watch
82:35 the entire future of the universe unfold
82:37 in a matter of seconds seeing the rise
82:40 and fall of galaxies the birth and death
82:42 of stars and perhaps even the end of
82:45 time itself this Eerie experience at the
82:48 Event Horizon represents a point where
82:50 the laws of physics as we know them
82:52 start to break down where space and time
82:55 blur into something
82:57 unrecognizable the astronaut's fate past
83:00 the Event Horizon remains a mystery
83:03 hidden from view by the very nature of
83:05 the black hole
83:06 itself another part of this effect is
83:09 the way black holes curve space
83:11 itself in everyday life we live in what
83:14 seems like a flat three-dimensional
83:16 world where the shortest distance
83:18 between two points is a straight line
83:21 but near a black hole space becomes
83:23 curved to the point where that straight
83:25 line warps and twists if we imagine
83:29 space as a flat rubber sheet a black
83:31 hole would be like a heavy weight
83:33 pressing down on the sheet creating a
83:35 deep funnel-like
83:37 indentation anything moving close to
83:40 this indentation would be pulled toward
83:41 it forced to follow the curved paths
83:44 created by the gravity of the black hole
83:47 for an object moving through this curved
83:49 space the experience is unsettlingly
83:52 strange it wouldn't feel as if it were
83:54 being pulled along a curved path but
83:57 rather that the very fabric of space
83:59 itself was bending beneath it drawing it
84:01 closer to the black hole's core even
84:04 light which usually travels in straight
84:07 lines is forced to bend and warp in the
84:09 presence of this immense gravity this is
84:12 why black holes appear so dark light
84:15 can't escape the Event Horizon and any
84:18 light emitted from an object near the
84:19 black hole is either pulled inward or
84:22 stretched to the point of invisibility
84:25 the closer light gets to the black hole
84:27 the more it loses its energy becoming
84:30 redder and fainter to a distant Observer
84:33 this creates a phenomenon called
84:35 gravitational red shift light coming
84:38 from the astronaut falling into the
84:40 black hole would appear increasingly red
84:42 and dim as they neared The Event Horizon
84:45 until it faded from view altogether
84:48 leaving the astronaut's image to
84:50 disappear into the
84:51 darkness the edge of a black hole Event
84:54 Horizon isn't just a physical boundary
84:57 it's a boundary in our understanding the
85:00 way black holes manipulate time and
85:02 space seemingly defying the usual rules
85:05 hints at a hidden layer of physics that
85:07 we have yet to
85:08 uncover some scientists believe that
85:10 studying black holes could eventually
85:12 lead us to a Theory of Everything a
85:14 single framework that explains both the
85:16 smallest particles and the largest
85:18 Cosmic
85:20 structures
85:22 spaghettification the gruesome fate of
85:25 objects near a black hole
85:27 spaghettification is the stretching and
85:29 elongating of an object as it approaches
85:31 a black holes Event
85:33 Horizon anything that gets close enough
85:36 whether it's a star a planet or a person
85:39 will face this fate if it drifts too far
85:42 into the gravitational grip of a black
85:44 hole on our planet gravity pulls
85:48 everything downwards keeping us grounded
85:50 to the surface but this force is
85:52 relatively weak compared to what happens
85:54 near a black hole the closer you get to
85:57 a black hole the more intense the
85:59 gravitational pull becomes and because
86:02 black holes are so incredibly dense with
86:04 all their Mass concentrated in a tiny
86:07 space their gravitational field
86:09 intensifies at a rate that far exceeds
86:12 anything we experience on Earth for an
86:15 object approaching a black hole the
86:17 difference in gravitational pull from
86:19 one end of the object to the other
86:21 becomes enormous imagine an astronaut
86:24 drifting toward a black hole feet first
86:27 the gravitational force pulling on the
86:29 astronaut's feet would be significantly
86:31 stronger than the force pulling on their
86:33 head simply because their feet are
86:35 closer to the black hole this difference
86:38 in force is known as a tidal force with
86:41 the feet being pulled far more intensely
86:43 than the head the astronaut's body would
86:45 start to stretch elongating like a piece
86:48 of spaghetti the closer they get to the
86:51 black hole the stronger this effect
86:53 becomes until the entire body is
86:55 stretched into a thin elongated shape as
86:59 the tidal forces increase the
87:01 spaghettification process doesn't just
87:03 stretch the object it also compresses it
87:06 horizontally making it narrower and
87:08 narrower while it gets longer and longer
87:12 essentially the object becomes a thin
87:14 line pulled toward the black hole in an
87:17 almost streamlike fashion eventually
87:21 these forces become so extreme that they
87:23 can over come the atomic bonds holding
87:25 the object together at this point the
87:28 astronaut or any object would be torn
87:31 apart completely disintegrated into
87:34 atoms that continue their descent toward
87:36 the Event
87:37 Horizon for a human Observer this
87:40 process would be unimaginably painful
87:43 and frightening but interestingly the
87:46 victim wouldn't necessarily be able to
87:48 feel the spaghettification at first
87:51 especially if they were falling into a
87:53 massive black hole
87:55 larger black holes have event Horizons
87:57 far from their Central singularities
88:00 meaning that the tidal forces near the
88:02 Event Horizon aren't quite as
88:04 extreme this would allow the person to
88:06 cross the Event Horizon without
88:08 immediate
88:09 disintegration it's only as they move
88:11 closer to the singularity the point at
88:14 the very center of the black hole where
88:17 the tidal forces reach their Peak
88:19 pulling the object apart atom by atom in
88:23 smaller black holes however the story is
88:26 different these black holes have more
88:28 intense tidal forces closer to their
88:30 event Horizons meaning that any object
88:33 nearing this boundary would begin
88:35 experiencing spaghettification well
88:38 before Crossing into the black hole in
88:40 these cases spaghettification becomes
88:43 unavoidable right outside the Event
88:45 Horizon anything that gets too close is
88:48 rapidly pulled into the elongated shape
88:51 and disintegrated before even reaching
88:54 the point of no
88:56 return it's not just hypothetical
88:59 astronauts who would experience this
89:01 fate stars that wander too close to a
89:04 black hole can also be pulled apart and
89:06 stretched by these same tidal forces
89:09 when a star falls under the influence of
89:11 a black hole the star's outer layers are
89:14 stretched and pulled away forming long
89:16 twisting streams of hot gas that spiral
89:19 into the black hole as these Stellar
89:21 remnants move inward they heat up to
89:24 millions of degrees creating brilliant
89:26 flares of X-ray radiation that can be
89:28 observed from
89:30 Earth this phenomenon known as a tidal
89:33 disruption event gives astronomers a
89:35 rare opportunity to witness
89:37 spaghettification on a massive
89:39 scale observing these events helps
89:42 scientists estimate the black hole's
89:44 mass by studying how a star is pulled
89:47 apart and the rate at which its gas
89:49 spirals inward astronomers can determine
89:52 just how much gravitational force the
89:53 black black hole is exerting which in
89:55 turn tells them more about the black
89:58 hole's size and influence the great
90:01 attractor a super cluster pulling black
90:04 hole mystery the great attractor is a
90:06 gravitational Enigma located in a region
90:08 of space hidden behind the thick clouds
90:11 of dust and stars of our own Milky Way
90:13 making it difficult to observe directly
90:16 yet even without a clear view of what's
90:18 there astronomers know that something
90:20 incredibly massive and Powerful is
90:23 pulling galaxies towards it including
90:25 our own Galaxy the force exerted by this
90:28 unseen presence known as the great
90:30 attractor is so immense that it's
90:32 influencing the movements of entire
90:34 Galactic clusters across millions of
90:36 light years in the vast emptiness of the
90:39 universe where galaxies often drift
90:42 apart it's remarkable to find such a
90:44 powerful Center of attraction that
90:46 defies the norm most galaxies are
90:49 expected to follow a pattern of
90:50 recession moving away from each other
90:53 due to the expans ion of the universe
90:55 but in the area surrounding the great
90:57 attractor galaxies aren't moving away
91:00 instead they seem to be converging
91:02 towards a central point this convergence
91:05 suggests the presence of a gravitational
91:07 force strong enough to overcome the
91:10 natural expansion of the universe in
91:12 that region creating a strange Cosmic
91:16 imbalance astronomers initially
91:19 estimated that this gravitational
91:20 anomaly was located around 200 million
91:23 light years AO away in the direction of
91:25 the constellation
91:26 Centaurus however pinpointing the exact
91:29 nature of the greater tractor has proven
91:32 challenging because it sits in a region
91:34 of space known as the zone of avoidance
91:37 our view is blocked by the gas dust and
91:40 stars within the plane of the Milky
91:42 Way radio telescopes and x-ray
91:45 observatories have allowed scientists to
91:47 peer through this barrier to some extent
91:49 but the data remains incomplete one of
91:52 the prevailing theories is that the
91:54 greater tractor is associated with a
91:56 supercluster of galaxies a vast
91:59 structure made up of many smaller Galaxy
92:02 groups bound together by gravity
92:05 specifically some researchers believe
92:07 that the greater tractor may be part of
92:09 the larger lanaka supercluster which
92:12 includes the Virgo cluster to which the
92:14 Milky Way belongs however this only
92:17 raises further questions as
92:19 superclusters themselves are massive but
92:21 usually spread out with enough empty
92:23 space between galaxies to prevent such
92:25 intense gravitational influence in any
92:28 one area for the great ATT tractor to be
92:30 pulling galaxies inward so strongly
92:33 something extremely dense and massive
92:34 must be at its core this is where the
92:37 possibility of black holes comes into
92:40 play astronomers have considered that
92:42 the great attractor might Harbor a
92:44 collection of super massive black holes
92:46 each capable of exerting powerful
92:48 gravitational
92:50 influence if this were the case these
92:53 black holes would not be isolated but
92:55 rather packed together within the core
92:57 of a vast Galactic cluster such an
93:00 assembly could explain the intensity of
93:02 the gravitational pool as the combined
93:04 masses of multiple black holes would
93:07 generate a force unlike anything we
93:09 typically observe on this
93:11 scale however for black holes alone to
93:14 account for this level of attraction
93:16 they would need to be extraordinarily
93:19 massive or gathered in an unusually high
93:22 concentration unlike anything observed
93:24 in more familiar parts of the
93:27 universe some researchers proposed that
93:29 the greater tractor could be a dense
93:32 concentration of dark matter which could
93:34 explain why we can't see it and why it
93:37 exerts such a powerful influence on
93:39 surrounding
93:40 galaxies interaction between dark matter
93:43 and black holes in this area May amplify
93:45 the gravitational force creating the
93:47 pull we observe if a large amount of
93:50 dark matter is clustered in this hidden
93:52 region it could be influencing the
93:54 movement of galaxies without us ever
93:56 seeing what's actually there researchers
93:59 have identified another anomaly called
94:01 the shapley supercluster located even
94:04 farther away which appears to be pulling
94:06 galaxies in a similar way this suggests
94:10 that there might be a chain of massive
94:11 structures with one region of
94:13 gravitational pull giving way to an even
94:16 larger one in a kind of cosmic relay
94:19 where matter is drawn from one massive
94:21 structure to the
94:22 next if black holes do contribute to the
94:25 great ATT tractor's Mass they might
94:27 represent the end points of countless
94:29 galaxies and star clusters that have
94:31 been consumed over billions of years
94:34 super massive or ultramassive black
94:36 holes could merge into even bigger black
94:39 holes contributing to the gravitational
94:41 mass and slowly building up over time
94:45 this would mean that the greater tractor
94:47 isn't a static object but an evolving
94:50 structure that grows as more material is
94:53 drawn
94:55 in
94:56 Sagittarius A asterisk the super massive
95:00 black hole at our Galaxy's heart at the
95:03 center of the Milky Way lies a cosmic
95:06 giant the super massive black hole
95:08 Sagittarius A asterisk this object
95:12 nestled within the galactic core about
95:14 26,000 light years away from Earth
95:17 remains largely invisible to the naked
95:19 eye hidden by clouds of gas and dust
95:21 that shroud the galactic center
95:24 roughly 4 million times the mass of our
95:26 sun Sagittarius A asterisk is a behemoth
95:29 of gravitational influence this massive
95:32 black hole holds sway over the central
95:34 regions of the Milky Way affecting the
95:37 orbits of nearby stars and influencing
95:40 the distribution of gas and dust within
95:42 our Galaxy's inner core its
95:44 gravitational pull helps stabilize the
95:47 region giving the Galaxy its
95:49 characteristic spiral shape without it
95:53 the core of the the Milky Way might be
95:54 far more chaotic with stars and gas
95:57 clouds flying off in unpredictable
96:00 directions in many galaxies super
96:02 massive black holes at their centers are
96:04 voracious eaters feeding on gas dust and
96:07 any star that Strays too
96:10 close however Sagittarius A asterisk
96:13 doesn't emit this kind of intense
96:15 energy astronomers consider it to be in
96:17 a dormant or inactive State meaning it
96:20 isn't actively feeding on surrounding
96:22 material at the same rate as other super
96:24 massive black holes while it does
96:27 occasionally flare up with bright
96:29 flashes of X-ray or infrared light these
96:32 episodes are brief and much less
96:34 dramatic than what we observe from black
96:36 holes in more active
96:38 galaxies one Theory suggests that there
96:40 simply isn't much material left around
96:42 it to feed on over time Sagittarius A
96:46 asterisk may have consumed or ejected
96:48 much of the nearby gas and dust leaving
96:51 it with a sparse environment in which to
96:53 operate without a consistent supply of
96:56 fuel the black hole doesn't have the
96:58 chance to release the intense radiation
97:00 that we see from more active Galactic
97:03 cause occasionally however a passing
97:06 cloud of gas or a star that drifts Too
97:08 Close might be pulled in causing a brief
97:11 period of activity in these rare cases
97:14 astronomers have observed Sagittarius A
97:16 asterisk brighten temporarily before
97:19 fading back into quietude even though
97:22 Sagittarius A Aster isk is mostly
97:24 inactive the stars that orbit close to
97:26 it provide vital clues about its nature
97:29 one of the most famous observations
97:31 involves a star known as S2 which
97:34 follows an elongated orbit around
97:36 Sagittarius A asterisk and comes
97:38 extremely close to the black hole at one
97:40 point in its path studying S2s movement
97:44 has allowed scientists to map out the
97:46 gravitational field of Sagittarius A
97:48 asterisk in detail when S2 reaches the
97:52 closest point of its orbit or pericenter
97:55 it experiences the intense pull of the
97:57 black hole accelerating up to 25 million
98:01 kmph magnetic fields are common in space
98:04 but around black holes they can twist
98:06 and contort in unusual ways astronomers
98:09 have noticed that the magnetic field
98:11 near Sagittarius A asterisk appears to
98:14 change direction frequently which may be
98:16 linked to the movement of hot gas and
98:19 the black holes
98:20 spin the environment around Sagittarius
98:23 a asterisk is also home to dense clouds
98:26 of gas and other intriguing
98:29 features one example is a mysterious
98:31 structure called the fery bubbles these
98:34 are enormous bubbles of high energy
98:36 particles that extend above and below
98:39 the plane of the Milky Way reaching far
98:41 beyond the Galaxy's disc some scientists
98:45 believe these bubbles might be linked to
98:47 past activity of Sagittarius A asterisk
98:50 possibly from a period when it was more
98:52 active and expelled Jets of material
98:54 into space if this theory is correct
98:58 then the fairy bubbles serve as a sort
98:59 of fossilized record preserving evidence
99:02 of a time when Sagittarius A asterisk
99:05 might have been more like the active
99:07 black holes we see in other galaxies
99:10 today though Sagittarius A asterisk is
99:13 currently calm it's possible that it
99:15 could become active again if a
99:17 sufficient amount of material Finds Its
99:18 way to the galactic center whether it's
99:21 a massive gas cloud or or a cluster of
99:24 stars that Strays too close an encounter
99:26 with Sagittarius A asterisk could
99:28 trigger a dramatic feeding event
99:31 temporarily lighting up the core of the
99:33 Milky Way with bursts of energy for now
99:36 however it remains a mostly silent giant
99:39 holding the Galaxy together in its
99:41 gravitational Embrace The Peculiar case
99:44 of GRS
99:47 1,915 plus
99:49 105 the largest Stellar black hole in
99:53 our Galaxy among the Stellar black holes
99:55 known in our galaxy GRS
99:58 1,915 + 105 stands out as one of the
100:02 most massive Stellar black holes in the
100:04 Milky Way with a mass estimated to be
100:07 between 10 and 14 times that of our
100:10 sun located about 28,000 light years
100:13 from Earth in the constellation Aquila
100:16 GRS
100:18 1,915 + 105 or V 1,487
100:23 aquili as it's also called is not just
100:26 notable for its size it's remarkable for
100:28 its unpredictable behavior and violent
100:31 activity this black hole which is part
100:34 of a binary system has intrigued
100:36 astronomers for years because of its
100:38 unusual outbursts and
100:40 fluctuations unlike many black holes
100:42 that experience periods of calm
100:44 punctuated by occasional bursts of
100:46 activity V
100:48 1,487 aquili seems to be constantly
100:51 teetering on the edge of a cosmic t tum
100:54 its emissions are erratic and Powerful
100:56 producing x-ray outbursts that can be
100:59 thousands of times brighter than our sun
101:02 these emissions are not only intense but
101:05 are also incredibly varied sometimes
101:07 they flare up in a matter of seconds
101:09 while at other times the outbursts last
101:12 for minutes or even hours this
101:14 volatility has earned V
101:17 1,487 AI a reputation as one of the most
101:21 unpredictable black holes ever studied
101:24 the source of this activity lies in the
101:26 black hool's feeding habits which are
101:29 unlike those of most other black holes
101:32 VI
101:33 1,487 aquili has a companion star from
101:36 which it draws matter siphoning gas away
101:39 through gravitational
101:41 forces in many black holes the accretion
101:44 disc is relatively stable allowing
101:46 material to gradually flow into the
101:48 black hole but in the case of V
101:51 1,487 aqua ey this disc is highly
101:56 unstable the material in the disc
101:58 accumulates and then releases in
102:00 powerful bursts leading to the frequent
102:03 and erratic flares astronomers believe
102:06 that these irregular bursts are due to a
102:08 process known as the Edington limit
102:10 which is a balance between the
102:12 gravitational pull of the black hole and
102:14 the outward pressure created by intense
102:17 radiation when too much material builds
102:19 up in the accretion disc the pressure
102:21 from radiation pushes back against the
102:23 gravitational pull temporarily halting
102:26 the inflow of matter this causes the
102:28 material to pile up only to crash inward
102:31 in a powerful wave when the pressure
102:35 eases this back and forth process
102:37 creates a cyclical pattern of buildup
102:40 and release resulting in the explosive
102:42 x-ray outbursts that make the black hole
102:45 so
102:46 unique the energetic outbursts from
102:50 v487 also create spectacular jet of
102:53 matter that shoot out from the black
102:55 holes poles these Jets known as
102:57 relativistic Jets travel at nearly the
103:00 speed of light and extend out thousands
103:02 of kilometers into space scientists
103:05 believe that the intense magnetic fields
103:07 around the accretion disc are
103:09 responsible for launching these
103:11 particles at such high speeds ejecting
103:14 them into space in narrow
103:16 beams much like its x-ray emissions the
103:20 Jets are highly erratic flickering on
103:22 and off and and changing in
103:24 intensity in fact astronomers have
103:27 classified V
103:28 1,487 aqualis activity into several
103:31 different modes each representing a
103:34 different combination of dis Behavior
103:36 x-ray emission and Jet
103:38 production some modes produce powerful
103:41 steady Jets While others generate weaker
103:44 sporadic ones black holes can spin at
103:47 various speeds depending on how much
103:49 angular momentum they have acquired over
103:51 their lifetimes for
103:55 v487 the spin is exceptionally High
103:58 close to the maximum possible rate for a
104:00 black hole this rapid rotation affects
104:03 everything around it from the shape of
104:05 the Event Horizon to the Dynamics of the
104:08 accretion disc in particular the high
104:11 spin rate likely enhances the power of
104:13 the Jets allowing them to reach
104:15 relativistic
104:17 speeds signis X1 the first confirmed
104:21 Stellar black hole and its EST ing power
104:24 in the world of black hole research
104:26 signus X1 holds a special place it was
104:29 the first Stellar black hole ever
104:30 confirmed and its Discovery marked a
104:33 milestone in our understanding of these
104:35 objects signis X1 is a powerful source
104:38 of X-ray emissions located in the
104:41 constellation signis about
104:43 7,300 light years from
104:45 Earth this black hole belongs to a
104:48 binary system locked in a gravitational
104:51 dance with a large companion star
104:54 in the early 1960s scientists detected
104:58 intense x-ray emissions coming from a
105:00 seemingly empty spot in the sky these
105:03 emissions puzzled astronomers at the
105:05 time x-rays from outer space were still
105:08 new territory and the sources of such
105:10 powerful emissions were not well
105:12 understood as scientists observed this
105:15 object more closely they realized that
105:17 it was emitting X-rays at a level far
105:19 beyond what ordinary Stars could produce
105:22 EV eventually the source of these x-rays
105:24 was traced back to a binary system where
105:27 a massive star now known as HD
105:51 22686859 Kip thorn in the 1970s that
105:55 signis X1 was not a black hole at that
105:59 time the idea of black holes was still
106:01 theoretical and many scientists were
106:04 hesitant to accept the existence of such
106:06 extreme
106:07 objects however as more data came in it
106:10 became clear that signus X1 met all the
106:13 criteria for a black hole a dense
106:16 invisible object with a gravitational
106:19 pull strong enough to prevent even light
106:21 from escaping
106:23 in 1990 after years of accumulating
106:26 evidence Hawking conceded the BET and
106:29 signus X1 was confirmed as a black
106:33 hole one of the defining features of
106:35 signus X1 is its intense and steady
106:38 x-ray output signus x1's companion star
106:42 HD2
106:44 26868 is a massive blue super giant and
106:48 it is losing material due to the
106:49 gravitational influence of the black
106:51 hole signus X1 pulls in a stream of gas
106:55 from this star forming a high energy
106:57 accretion disc the material in this disc
107:00 is compressed and heated to millions of
107:02 degrees creating a powerful x-ray glow
107:06 in fact the X-ray emissions from signus
107:09 X1 are one of the strongest x-ray
107:11 sources detectable from Earth the inner
107:14 regions of the accretion disc where
107:16 temperatures and densities are highest
107:19 emit the most intense x-rays creating a
107:22 spectacle that be observed across vast
107:25 distances astronomers have determined
107:27 that signus X1 is rotating at an
107:30 exceptionally High rate close to 790
107:33 times per second the high spin rate also
107:36 suggests that signis X1 may have
107:38 experienced a unique formation process
107:42 one possibility is that it formed from
107:44 the collapse of a very massive star that
107:46 imparted its angular momentum to the
107:48 black hole alternatively signis X1 could
107:52 have gained additional spin by accreting
107:54 material from its companion over time
107:57 since signus x1's companion star is
107:59 still relatively young it offers a rare
108:02 opportunity to observe a black hole in
108:04 the early stages of its life in a binary
108:06 system over time the companion star will
108:09 continue to lose Mass eventually
108:11 evolving into a different type of star
108:14 or possibly exploding as a supernova the
108:17 discovery of m87 asterisk a glimpse into
108:20 a super massive monster beyond our
108:22 galaxy
108:23 in April 2019 the world saw the first
108:26 ever image of a black hole that black
108:28 hole was m87 asterisk a super massive
108:32 giant sitting at the center of one of
108:33 the largest known galaxies messia 887
108:36 some 53 million light years away the
108:39 Blurred but iconic image captured by the
108:41 Event Horizon telescope or EHT was a
108:45 historic achievement marking the first
108:47 time humanity visually confirmed the
108:49 presence of a black hole's Event Horizon
108:52 MH 87 asterisk a black hole with a mass
108:55 of between 3 to 6 billion times that of
108:57 the sun was now within our reach at
108:59 least in terms of observation the Galaxy
109:03 M 87 itself is one of the most massive
109:06 galaxies in the nearby Universe located
109:09 in the Virgo cluster a collection of
109:11 galaxies bound together by gravity m87
109:14 is filled with stars gas and dust and at
109:17 its heart lies m87 asterisk it's a black
109:21 hole of a scale we rarely see a true
109:23 super massive black hole whose influence
109:25 stretches far across its Galaxy the
109:28 black hole's mass is so enormous that it
109:30 Alters the orbits of stars millions of
109:32 times farther out essentially
109:34 controlling the gravitational structure
109:36 of the entire
109:38 galaxy The Event Horizon telescope is
109:41 not a single telescope but rather a
109:43 Global Network of radio telescopes
109:45 spread across the planet these
109:48 telescopes located at sites like Hawaii
109:51 Mexico Antarctica and in Spain combine
109:54 their observations through a technique
109:56 known as very long baseline
109:57 interferometry or
109:59 vbi by linking up telescopes across
110:02 earth scientists effectively created a
110:04 planet-sized telescope capable of
110:06 capturing details at an unprecedented
110:09 level of precision each telescope in the
110:11 network collects radio waves emitted by
110:14 m87 asterisk Gathering data across vast
110:18 distances to build a detailed picture
110:20 the black holes incredible distance from
110:23 Earth would make it seem nearly
110:24 impossible to observe in such detail but
110:27 vlbi allowed scientists to achieve the
110:30 necessary
110:31 resolution this process required
110:33 algorithms that could fill in gaps in
110:35 data essentially reconstructing the
110:37 final image from incomplete
110:40 signals the resulting image of m87
110:43 asterisk wasn't sharp in the way we
110:45 might expect from a photograph instead
110:48 it was a hazy glowing ring encircling a
110:50 dark core this dark Center is the shadow
110:54 of the black hole the spot where gravity
110:56 is so strong that even light cannot
110:58 escape the glowing ring is created by
111:01 gas and dust heated to extreme
111:03 temperatures as they swirl around the
111:05 black hole close to the event
111:08 horizon it's here on this Edge that
111:12 light is bent by gravitational forces so
111:15 intense that it creates a ringlike
111:18 appearance general relativity predicted
111:20 the shape and structure of the event
111:22 Horizon's Shadow and the actual image of
111:25 m87 asterisk aligned remarkably well
111:28 with these predictions the dark Center
111:31 surrounded by The Ring of light fit the
111:34 theoretical models almost precisely for
111:37 physicists this was a significant moment
111:40 an observational confirmation that
111:41 general relativity still held up even in
111:44 the most extreme environments we can
111:46 imagine m87 asterisk is a particularly
111:50 active black hole meaning it feeds on a
111:52 steady supply of matter drawn from its
111:54 surroundings the swirling gas and dust
111:57 around m87 asterisk emit massive amounts
112:00 of energy and some of this material is
112:03 funneled into jets that shoot out from
112:05 the poles of the black hole the Jets
112:08 from m87 asterisk are among the most
112:11 powerful known capable of shaping the
112:14 surrounding Galaxy by blasting material
112:16 outward influencing star formation and
112:19 altering the distribution of gas within
112:21 M8 87 itself the material around m87
112:26 asterisk doesn't just spin in random
112:28 directions it forms an accretion disc
112:31 that is closely aligned with the
112:32 direction of the Jets by studying these
112:35 Jets and their orientation astronomers
112:38 can determine the black hole's rotation
112:40 and gain insights into how m87 asterisk
112:43 interacts with the Galaxy the fact that
112:46 m87 asterisk produces Jets at all
112:49 suggests it's a rapidly spinning black
112:51 hole
112:52 as the rotation of the black hole's
112:54 magnetic field likely plays a role in
112:57 driving the
112:58 Jets the EHT project involved hundreds
113:01 of scientists engineers and institutions
113:04 from around the world each contributing
113:07 expertise resources and time it took
113:10 years to coordinate the telescopes
113:12 process the data and reconstruct the
113:14 image in fact the amount of data
113:17 collected by the EHT was so vast that it
113:20 couldn't be transmitted digitally
113:22 instead instead hard drives were flown
113:24 across the world to be
113:26 analyzed a black hole consuming its own
113:29 Galaxy the taale of NGC
113:33 4,889 in the distant coma cluster lies a
113:36 massive elliptical galaxy named NGC
113:40 4889 home to one of the largest black
113:43 holes known to
113:44 astronomers this super massive black
113:46 hole hidden within the center of NGC
113:50 4889 has a mass estimated to be around
113:53 21 billion times that of the sun about 3
113:56 to six times larger than the humongous
113:59 m87
114:01 asterisk that's about
114:03 5,200 times the mass of the black hole
114:06 at the center of our own Milky Way NGC
114:11 4,889 is a giant elliptical galaxy
114:14 meaning it doesn't have the spiral arms
114:16 or disc-shaped structure seen in
114:18 galaxies like the Milky Way instead it
114:22 appears is a smooth rounded mass of
114:24 stars and Interstellar
114:25 material the presence of this colossal
114:28 black hole has likely contributed to
114:30 this shape as well as to the sparse and
114:32 relatively uniform distribution of stars
114:34 throughout the Galaxy massive black
114:36 holes especially those of this size
114:39 often play a major role in determining
114:41 the form of their host galaxies and NGC
114:45 4,889 black hole is no exception at the
114:49 heart of NGC 488 9 the black hole has an
114:54 enormous gravitational sphere of
114:56 influence stars that pass close to this
114:59 central region have their orbits altered
115:01 or even disrupted entirely for any
115:04 material that Ventures Too Close there's
115:06 a point of no return once it crosses the
115:09 Event Horizon it's pulled inward with no
115:11 chance of Escape as a result the core of
115:14 NGC
115:17 4,889 is a dynamic and intense place
115:20 where the central black hole exer zerts
115:22 constant pressure on its
115:24 surroundings over time this Relentless
115:27 gravitational force has stripped the
115:29 central regions of NGC
115:34 4,889 of much of their star forming gas
115:37 gas clouds that drift near the black
115:39 hole can be trapped by its pull where
115:42 they become part of an accretion disc as
115:45 the gas compresses and heats up it
115:47 releases an enormous amount of energy
115:49 often in the form of powerful jets that
115:52 shoot out from the Galaxy's Center
115:54 normally a Galaxy Star formation is
115:57 fueled by cool gas which condenses into
116:00 dense clouds where new Stars Are Born
116:03 but in NGC
116:05 4889 the central black hole has heated
116:08 and expelled much of this gas disrupting
116:10 the conditions necessary for Star
116:13 formation the powerful Jets and
116:15 radiation emitted by the black hole
116:17 secretion disc have driven gas away from
116:19 the Galaxy's core creating an
116:21 environment where new stars struggle to
116:24 form the Galaxy's current population of
116:27 stars is likely very old having formed
116:30 billions of years ago when conditions
116:32 were
116:33 different since then the galaxy has
116:36 become a place of relative quiet with
116:38 little new star formation to replenish
116:40 its aging Stellar
116:42 population during an earlier era likely
116:45 several billion years ago this black
116:48 hole could have been a
116:50 quaza quazar are among the the brightest
116:52 objects in the universe and if NGC
116:56 4889 black hole was once a quaza it
117:00 would have emitted such powerful
117:02 radiation that it would have shaped not
117:04 only the structure of its own Galaxy but
117:06 also potentially impacted nearby
117:08 galaxies in the coma cluster Over time
117:11 however the black hole's activity may
117:14 have slowed as it exhausted the
117:16 available gas supply settling into a
117:18 quieter phase where it no longer shines
117:21 as brightly
117:22 without enough cool gas to fuel new star
117:24 formation NGC
117:27 4889 has evolved into a Galaxy where old
117:30 Stars dominate forming a stable but
117:33 inactive Stellar population in this way
117:36 the black hole's hunger for material has
117:39 shaped the very nature of the Galaxy
117:42 creating a sort of cosmic desert where
117:44 new stars rarely emerge one intriguing
117:48 question that astronomers are still
117:50 investigating is whether NGC
117:53 4889 black hole is still growing
117:57 although it's no longer as active as it
117:59 might have been during its quazer phase
118:01 there's a possibility that the black
118:03 hole continues to draw in small amounts
118:05 of gas and other material as it does it
118:09 may release occasional bursts of energy
118:12 these sporadic emissions could reveal
118:14 clues about the black hole's current
118:15 state providing a glimpse into the
118:18 mechanisms that drive its
118:20 activity quantum entanglement at the
118:23 Event Horizon a new frontier of study
118:27 quantum entanglement is a fascinating
118:29 property in quantum mechanics where two
118:31 particles become so deeply connected
118:33 that the state of one instantly affects
118:35 the state of the other no matter how far
118:37 apart they are this connection is so
118:40 immediate that it appears to happen
118:42 faster than the speed of light something
118:44 Einstein famously called spooky action
118:46 at a distance entanglement is one of the
118:49 core principles of quantum mechanics
118:53 when applied to black holes entanglement
118:55 presents both exciting possibilities and
118:58 challenges particularly when it comes to
119:00 what happens to information near the
119:01 Event
119:02 Horizon one of the great puzzles in
119:05 black hole physics is what happens to
119:07 information that falls into a black hole
119:10 in the world of quantum mechanics
119:12 information about particles such as
119:14 their spin charge and other properties
119:17 can't simply disappear but according to
119:19 general relativity anything that crosses
119:22 the Event Horizon should vanish consumed
119:25 by the black hole and lost
119:27 forever this apparent contradiction
119:29 between quantum mechanics and relativity
119:32 has led to what's known as the
119:34 information
119:35 Paradox many physicists believe that
119:38 understanding quantum entanglement
119:39 around the Event Horizon might provide
119:42 clues to resolving this Paradox one idea
119:45 is that particles that approach The
119:47 Event Horizon become entangled with
119:49 particles on the other side creating a
119:52 sort of quantum bridge between the
119:54 inside and outside of the black hole
119:57 this entanglement could in theory
120:00 preserve information even if it crosses
120:02 the Event
120:03 Horizon in this scenario The Event
120:05 Horizon would act almost like a hologram
120:08 storing a faint shadow of all the
120:10 information that has ever fallen into
120:12 the black hole a much debated Theory
120:14 known as the firewall Paradox emerged in
120:17 recent years challenging the
120:19 conventional view of black holes as
120:21 smooth calm boundaries in space
120:24 according to this Paradox if information
120:26 is truly preserved at the Event Horizon
120:28 through entanglement it could lead to a
120:30 buildup of energy at this boundary this
120:33 energy in turn might create a firewall a
120:36 searing wall of radiation that would
120:38 destroy anything approaching the Event
120:40 Horizon for decades scientists believed
120:43 that an object would be able to cross
120:44 the Event Horizon without any dramatic
120:46 change in its experience following the
120:49 logic of general
120:50 relativity the firewall Paradox however
120:53 proposes a scenario where instead of
120:56 falling smoothly into a black hole
120:58 anything that approaches The Event
121:00 Horizon would be obliterated by intense
121:04 radiation this idea has sparked intense
121:06 debate among physicists with some
121:09 arguing that such a barrier conflicts
121:11 with other well-established principles
121:12 of
121:13 physics if firewalls exist they would
121:16 violate what is known as the equivalence
121:19 principle a Cornerstone of Einstein's
121:21 theory of general relativity which
121:24 states that Free Falling observers
121:26 should not experience any strange
121:27 effects at the event
121:29 horizon yet if firewalls do not exist
121:33 then how does Quantum information Escape
121:35 being destroyed inside the black hole
121:38 research in quantum mechanics suggests
121:41 that entanglement at the Event Horizon
121:43 could allow for a form of information
121:45 leakage where the properties of
121:47 particles that fall into the black hole
121:50 remain entangled with particles outside
121:51 IDE it this idea leans on what
121:54 physicists call monogamy of entanglement
121:57 which states that particles cannot be
121:59 maximally entangled with more than one
122:02 other particle at the same time when
122:04 applied to black holes this concept
122:07 implies that if a particle outside the
122:09 Event Horizon is entangled with a
122:10 particle that has fallen in this
122:12 connection might break previous
122:14 entanglements releasing information in a
122:16 subtle and indirect way through this
122:19 mechanism the information that enters a
122:22 black hole might not be entirely lost
122:24 but could instead slowly radiate back
122:27 into the universe spread out over time
122:29 through particles that escape the black
122:31 holes
122:32 pull physicists are exploring how to
122:34 test these theories using the tools of
122:37 quantum mechanics and general relativity
122:40 but the extreme environments near black
122:42 holes make direct observation difficult
122:45 despite these challenges advances in
122:47 quantum physics are helping researchers
122:50 develop theoretical Frameworks to
122:52 understand entanglement at the Event
122:54 Horizon experiments in Quantum
122:56 information science such as those that
122:58 manipulate entangled particles in the
123:00 lab are providing insights that
123:03 scientists hope to apply to the study of
123:05 black
123:07 holes by understanding how entanglement
123:09 Works in controlled settings they aim to
123:12 gain a better understanding of how
123:13 entanglement might behave under the
123:16 intense gravitational forces around
123:18 black
123:19 holes some physicists speculate that
123:22 entangled particles on opposite sides of
123:24 a black hole's Event Horizon could
123:26 create a type of microscopic Wormhole
123:29 linking distant points in SpaceTime this
123:32 idea known as ER equal sign epr combines
123:36 Concepts from Einstein and physicist
123:37 Nathan rosen's work on wormholes AKA
123:40 erer with Einstein Podolski and rosen's
123:44 work on quantum entanglement AKA epr
123:47 while this theory is highly speculative
123:49 it opens up the possibility that
123:51 entanglement might play a role in
123:53 shaping the structure of SpaceTime
123:55 itself especially in the regions
123:58 surrounding black holes the phenomenon
124:01 is incredibly complex involving
124:03 calculations that stretch the limits of
124:05 our most advanced physics
124:07 models some scientists speculate that
124:10 fully understanding entanglement around
124:12 black holes could require a new form of
124:15 mathematics or even a new approach to
124:17 physics altogether the mathematical
124:20 tools we currently have were developed
124:22 to describe worlds that follow
124:24 consistent rules and predictable
124:25 patterns but black holes defy many of
124:28 these conventions The Singularity
124:30 problem do black holes really have
124:33 infinite
124:34 density the common understanding based
124:36 on Einstein's theory of general
124:38 relativity suggests that a singularity
124:40 forms a place of infinite density where
124:43 all the matter that has fallen into the
124:45 black hole is squeezed into a point of
124:47 zero volume at first glance this might
124:49 sound straightforward gravity Crush is
124:52 everything down to an unimaginable
124:53 degree creating a place where mass and
124:55 density Spike to values that reach
124:58 infinity but infinite density is a
125:00 concept that doesn't quite fit with how
125:02 we understand physics it leaves us with
125:04 a challenging puzzle is it possible that
125:07 black holes really have infinite density
125:10 or is something else happening deep
125:11 within in a conventional sense physics
125:14 deals with measurable quantities and
125:16 defined limits and infinity isn't a
125:19 number or value that physicists work
125:21 with comfortably when we speak about the
125:24 infinite density at the singularity it's
125:26 often more a reflection of the
125:28 limitations of our current theories than
125:30 of what's actually there the mathematics
125:33 of general relativity breaks down when
125:35 it tries to describe what's happening
125:37 inside a black hole it can't handle the
125:39 intense gravitational field or the
125:41 compression of matter Beyond a certain
125:44 point so instead of providing a clear
125:46 answer the equations of Relativity leave
125:49 us with this notion of an infinitely
125:51 small infinitely dense point at the core
125:54 of a black hole which is known as The
125:57 Singularity the concept of a singularity
125:59 has always been a thorny issue for
126:01 physicists largely because it highlights
126:03 a conflict between general relativity
126:06 and quantum mechanics when you try to
126:08 apply both theories to the singularity
126:11 they Clash general relativity insists
126:14 that gravity is so strong at the
126:16 singularity that it warps SpaceTime
126:19 infinitely but quantum mechanics which
126:22 describes matter at tiny scales suggests
126:25 that there should be some sort of limit
126:26 to how much matter can be compressed
126:29 these two theories refuse to reconcile
126:31 with each other when faced with the
126:33 singularity which has led physicists to
126:35 search for a more complete theory of
126:37 quantum gravity something that can
126:39 describe both the massive gravitational
126:41 forces of black holes and the tiny
126:44 Quantum particles that fall into them
126:47 several ideas have been proposed to
126:49 address this Singularity problem with
126:51 the goal of explaining what happens
126:53 inside black holes without resorting to
126:56 Infinity one of the leading Concepts is
126:59 string theory which suggests that the
127:02 basic building blocks of the universe
127:04 aren't particles like electrons or
127:06 quarks but rather tiny vibrating strings
127:10 of energy these strings can take on
127:13 different forms and interact with one
127:16 another in ways that could potentially
127:18 smooth out the singularity avoiding
127:20 infinite density it and creating a
127:23 finite if incredibly small core within
127:26 the black
127:28 hole another approach is called Loop
127:30 quantum gravity According to which space
127:33 is not a continuous fabric but is
127:35 instead made up of tiny discrete units
127:38 or
127:39 Loops this Theory suggests that there's
127:42 a fundamental graininess to space at the
127:44 smallest scales and this could provide a
127:47 natural limit to the density that matter
127:50 can reach inside a black hole in this
127:53 view rather than collapsing into an
127:55 infinitely small point the matter inside
127:57 a black hole might form a highly compact
128:01 but finite structure where space is bent
128:04 but not torn into
128:06 Infinity there's also the idea that
128:08 rather than having an actual point of
128:10 infinite density The Singularity could
128:13 be a phenomenon related to The Event
128:15 Horizon
128:16 itself some physicists propose that from
128:19 the perspective of an outside Observer
128:22 the matter that falls toward a black
128:23 hole never actually reaches the
128:26 singularity due to the effects of
128:28 extreme time dilation near the Event
128:30 Horizon it appears as though the
128:32 infalling matter slows down more and
128:34 more freezing just above the Event
128:36 Horizon As Time stretches toward
128:40 Infinity in this interpretation The
128:43 Singularity isn't so much a place inside
128:45 the black hole as it is a consequence of
128:48 the Distortion of SpaceTime around it
128:51 quantum mechanics offer some hints about
128:53 what might be happening at the
128:55 singularity particularly with Concepts
128:57 like the uncertainty
128:59 principle this principle suggests that
129:01 there's a fundamental limit to how
129:03 precisely we can know certain properties
129:06 like a particle's position and momentum
129:08 at the same time in the intensely
129:11 compressed environment of a black hole
129:13 this uncertainty could create a
129:15 situation where particles maintain a
129:17 certain Quantum fuzziness which would
129:19 prevent them from being crushed into a
129:21 single
129:22 point this kind of quantum pressure
129:25 might counteract the pull of gravity
129:27 creating a sort of quantum core instead
129:29 of a true Singularity with infinite
129:32 density Steven Hawking and others have
129:35 contributed additional ideas to the
129:37 mystery of the
129:38 singularity Hawking proposed that black
129:41 holes aren't completely black but
129:43 instead emit Hawking radiation a faint
129:46 glow of particles that gradually reduces
129:48 the black holes Mass over time if black
129:52 holes can slowly evaporate and lose Mass
129:54 it raises questions about what would
129:56 happen to the singularity as the black
129:58 hole shrinks some theories suggest that
130:02 as the black hole loses Mass the intense
130:05 gravitational forces would decrease
130:07 possibly revealing a finite structure at
130:09 the center rather than a
130:11 singularity in this scenario the black
130:14 hole might eventually evaporate entirely
130:17 leaving behind only a tiny Remnant but
130:20 one that doesn't have infinite density
130:23 some propose that instead of crushing
130:25 matter down to a point of infinite
130:27 density the intense gravitational forces
130:30 inside a black hole might create a
130:32 passage to another universe or a new
130:34 region of space this idea often called a
130:38 white hole suggests that black holes
130:41 could act as portals with matter
130:43 entering through the black hole and
130:45 emerging somewhere
130:47 else holographic black holes a new
130:50 Theory that changes everything we know
130:53 the holographic black hole idea posits
130:56 what if black holes could store
130:58 information in a way that resembles a
131:01 hologram this idea doesn't refer to
131:03 Holograms like the ones used in
131:05 entertainment but rather a mathematical
131:07 description in which three-dimensional
131:09 information is represented on a
131:12 two-dimensional surface the theory
131:14 suggests that a black hole's Event
131:17 Horizon might contain everything we need
131:19 to know about what's inside much like
131:22 how a hologram on a credit card contains
131:24 information about a three-dimensional
131:26 image on its flat
131:28 surface one possible solution to the
131:30 information Paradox of black holes came
131:33 from the development of the holographic
131:35 principle introduced by physicists
131:38 Gerard H and Leonard
131:40 suskin they suggested that perhaps all
131:43 the information that falls into a black
131:44 hole doesn't disappear inside it but
131:47 rather gets encoded on the Event Horizon
131:49 itself according to to this Theory the
131:52 black hole surface would contain all the
131:54 details about everything that has ever
131:56 fallen into it to visualize the
131:59 holographic principle it helps to
132:01 imagine an ordinary hologram where the
132:03 depth and details of a three-dimensional
132:05 image are stored on a flat
132:07 two-dimensional surface in the case of a
132:10 black hole imagine that the data about
132:12 the three-dimensional matter falling
132:14 into it could be represented entirely on
132:17 the two-dimensional Event Horizon this
132:20 means that even though matter vanishes
132:22 from view once it crosses the Event
132:24 Horizon the black hole surface could
132:26 retain an imprint of that matter in a
132:29 way that we don't yet fully understand
132:32 reducing the need for a mysterious
132:34 internal process that could potentially
132:37 destroy the
132:38 information if the holographic principle
132:41 applies to black holes it might also
132:43 apply to the entire universe suggesting
132:46 that the three-dimensional reality we
132:48 experience could be a kind of hologram
132:50 with with its fundamental properties
132:52 encoded on a two-dimensional surface at
132:55 the boundaries of the universe this
132:58 holographic universe theory is a bold
133:00 idea but it's one that physicists are
133:03 still investigating and debating one way
133:06 scientists have tried to test the
133:08 holographic principle is by studying the
133:10 thermodynamics of black holes
133:12 particularly through something known as
133:14 black hole entropy entropy in physics is
133:18 a measure of the disorder or information
133:21 content of a
133:22 system Jacob beinstein a physicist who
133:26 studied black hole thermodynamics
133:28 theorized that the entropy of a black
133:30 hole was proportional to the surface
133:31 area of its Event Horizon this was
133:34 surprising because entropy usually
133:36 depends on the volume of a system but if
133:40 black holes store information on their
133:42 surfaces it makes sense that their
133:44 entropy would depend on surface area
133:47 instead for those who study quantum
133:49 mechanics the holograph principle offers
133:52 a bridge between relativity and quantum
133:54 theory the holographic principle
133:56 suggests that if space itself has a kind
133:59 of holographic encoding then gravity
134:01 could be explained in terms of quantum
134:04 information this is a significant step
134:07 toward reconciling the two theories
134:09 possibly leading to a Theory of
134:12 Everything scientists have explored
134:14 these Concepts using mathematical
134:16 Frameworks such as string theory in
134:19 string theory a hypothetical anti-d
134:22 space might resemble the interior of a
134:24 black hole and a quantum theory on its
134:26 boundary would fully describe everything
134:28 within it this has led to a
134:31 groundbreaking idea known as The anti-d
134:33 Sitter conformal field Theory
134:34 correspondence frequently abbreviated as
134:37 ads CFT which proposes that certain
134:40 gravitational systems could be described
134:42 entirely by quantum mechanics on their
134:45 boundaries although highly abstract this
134:48 correspondence provides a model that
134:50 closely resembles the the concept of a
134:52 holographic black hole giving physicists
134:55 a way to test aspects of the holographic
134:57 principle in a controlled theoretical
135:00 setting while experiments to directly
135:03 observe holographic black holes are
135:05 challenging researchers have developed
135:07 Advanced Computer simulations to model
135:10 how black holes could store information
135:12 on their event Horizons these
135:14 simulations use the latest understanding
135:17 of quantum field Theory to explore how
135:19 particles behave near a black hole's
135:21 Edge through these simulations
135:24 scientists hope to better understand the
135:26 encoding process that might preserve
135:29 information in a way similar to a
135:31 hologram if holographic black holes are
135:34 indeed real they may solve the
135:36 information Paradox and provide a new
135:38 perspective on how information behaves
135:40 in extreme
135:41 environments instead of thinking of
135:43 black holes as objects that destroy
135:46 information we would view them as unique
135:48 structures that transform information
135:51 compressing it into a flat record on
135:53 their
135:54 surfaces this perspective could also
135:56 Inspire new ways of thinking about data
135:58 storage and Computing where information
136:01 is preserved in a minimal compact form
136:04 yet retains all the complexity of the
136:05 original
136:07 data the idea that black holes could act
136:09 as Cosmic Holograms suggests that what
136:12 we see as a void or collapse is actually
136:15 a profound transformation
136:17 process this shift in thinking could
136:20 have profound implications for our
136:22 understanding of entropy Quantum
136:25 information and even the fundamental
136:27 structure of the
136:28 universe if the universe is indeed
136:31 holographic in nature it would imply
136:34 that the depth of space is in a way an
136:37 illusion a product of information
136:39 arranged on surfaces if space and depth
136:42 are just expressions of information what
136:44 does it mean to live in a
136:45 three-dimensional
136:47 Universe Interstellar travel and black
136:49 holes science fiction or future
136:54 reality could black holes serve as
136:56 Cosmic gateways to distant regions of
136:58 the universe or perhaps even as
137:01 shortcuts through space and time or
137:03 could their immense gravitational forces
137:06 act like a slingshot giving a spacecraft
137:08 the speed it would need to explore stars
137:11 and galaxies far beyond our reach the
137:14 most straightforward way that black
137:16 holes could contribute to Interstellar
137:18 travel is through their powerful
137:19 gravitational pull
137:21 which could theoretically be used as a
137:23 gravitational slingshot in space
137:26 exploration gravitational slingshots
137:28 already work with planets when a
137:30 spacecraft passes close to a planet it
137:33 can pick up speed by using the planet's
137:35 gravity allowing it to conserve fuel
137:37 while reaching greater speeds the
137:40 gravity of massive bodies pulls the
137:42 spacecraft into a tighter orbit and as
137:44 it exits the orbit it escapes with
137:47 greater speed black holes are vastly
137:49 more massive than planets meaning the
137:51 slingshot effect would be
137:52 correspondingly powerful a ship that
137:55 passed close to a black hole might
137:57 achieve astonishing speeds even
137:59 approaching a significant fraction of
138:01 the speed of light yet while
138:04 gravitational slingshots around planets
138:06 are relatively safe black holes come
138:09 with inherent and extreme dangers a
138:12 black hole's gravitational field is so
138:14 intense that anything crossing the Event
138:16 Horizon is lost forever for a spacecraft
138:20 to use a black hole as a slingshot it
138:22 would have to pass Incredibly Close
138:24 without getting pulled inside a
138:26 miscalculation by even a fraction of a
138:28 degree could result in the craft
138:30 spiraling toward the Event Horizon
138:33 beyond that the tidal forces near a
138:35 black hole are also far more severe than
138:38 those around planets which means that
138:40 even a close pass might be dangerous
138:42 stretching and twisting the craft with
138:44 unimaginable Force still the idea of
138:47 using black holes in space travel
138:49 doesn't end with gravity ational
138:51 slingshots some theories suggest that
138:53 black holes particularly rotating black
138:55 holes known as Cur black holes could act
138:58 as portals or wormholes that connect
139:00 distant points in Space the concept of a
139:03 wormhole is hypothetical first proposed
139:06 by Albert Einstein and Nathan Rosen as
139:08 part of Einstein's general theory of
139:10 relativity wormholes are envisioned as
139:13 tunnels through SpaceTime where entering
139:15 one end could theoretically lead to an
139:17 exit far away in another region of space
139:20 possibly even another galaxy in theory
139:23 certain black holes might form the
139:25 entrance to such a tunnel however to
139:28 function as a wormhole that allows safe
139:30 passage a black hole would need specific
139:32 properties such as a stable structure
139:35 and a rotating ring-shaped
139:37 Singularity conditions that are still
139:39 purely
139:40 theoretical a typical black hole crushes
139:43 everything that falls in reducing it to
139:45 subatomic particles for a wormhole to
139:48 work it would need to somehow hold its
139:51 shape and not collapse on itself
139:53 allowing something to pass through
139:55 without being
139:56 destroyed some scientists have
139:58 speculated that exotic matter with
140:00 negative energy could stabilize a
140:03 wormhole preventing it from collapsing
140:06 but this kind of matter hasn't been
140:07 observed in nature even if it exists
140:10 creating or gathering enough of it to
140:12 stabilize a wormhole remains well beyond
140:15 our technological
140:17 capabilities beyond the stability issues
140:20 there is the question of time traveling
140:22 through a black hole or Wormhole would
140:25 involve extreme time dilation this time
140:28 Distortion could complicate any mission
140:31 that seeks to use black holes for travel
140:34 as the passage of time outside the black
140:36 holes influence could be drastically
140:38 different from what The Travelers
140:40 Experience One fascinating possibility
140:43 is that if an advanced civilization
140:45 could somehow harness a black hole's
140:47 energy they might be able to use it as a
140:50 near INF infite power source for
140:51 Interstellar travel a theoretical Black
140:54 Hole Drive could involve capturing
140:56 Hawking radiation or utilizing the black
140:59 hole's rotational energy to power a
141:02 spacecraft by approaching the black hole
141:04 and skimming its Event Horizon without
141:06 falling in a spacecraft might be able to
141:09 tap into this energy in a controlled way
141:13 black holes are already difficult to
141:15 approach safely but capturing Hawking
141:17 radiation or rotational energy would
141:20 require technology far beyond anything
141:22 we have
141:23 today extracting energy from a black
141:26 hole would involve capturing and
141:28 redirecting it a task that would likely
141:30 demand complex engineering and precise
141:33 navigation systems the idea is
141:36 fascinating but for now remains in the
141:38 domain of theoretical
141:42 speculation the future of black hole
141:45 research what new discoveries await
141:48 observing black holes has traditionally
141:50 been one of the biggest challenges in
141:52 astronomy by their very nature black
141:55 holes do not emit light in the way that
141:57 stars or galaxies do instead their
142:00 presence is detected through indirect
142:02 methods by observing the intense
142:04 gravitational effects they have on their
142:07 surroundings such as the way they bend
142:09 light affect nearby stars or emit
142:12 powerful x-rays as they pull in
142:15 matter however with each new generation
142:18 of telescopes sensors and computational
142:20 techniques scientists are beginning to
142:22 catch a clearer glimpse of black holes
142:24 and their behavior one of the most
142:27 revolutionary recent advancements was
142:30 the development of the Event Horizon
142:33 telescope the EHT was only the beginning
142:36 and its success has inspired even more
142:38 ambitious
142:40 projects plans are underway to enhance
142:43 the eht's capabilities by adding more
142:46 observatories to its Network which would
142:49 improve its resolution and allow it to
142:51 capture images of black holes with even
142:53 more detail the goal is to provide
142:56 sharper and more comprehensive views of
142:59 black hole's event Horizons capturing
143:01 finer details of the gas and plasma as
143:03 they swirl around the black hole's
143:06 Edge gravitational wave astronomy is
143:08 also still in its early stages but it
143:11 promises to be one of the most powerful
143:13 tools for studying black holes unlike
143:16 electromagnetic waves gravitational
143:18 waves are not hindered by dust or
143:20 obstacles in space allowing them to
143:23 travel directly from their source to
143:25 Earth this means that gravitational
143:27 waves can provide insights into black
143:29 holes hidden within dense or distant
143:32 regions of space that are otherwise
143:34 invisible in the coming years a new
143:37 generation of detectors including Lisa
143:40 the laser interferometer space antenna a
143:43 space-based gravitational wave
143:44 Observatory is expected to
143:47 launch Lisa will be more sensitive than
143:49 earth-based detectors and capable of
143:52 detecting lower frequency gravitational
143:54 waves potentially revealing a vast new
143:56 array of black hole interactions
143:59 including the merging of super massive
144:01 black holes another significant area of
144:04 research involves the study of black
144:06 holes in other wavelengths of light such
144:08 as X-rays and gamma rays these high
144:11 energy forms of light are often produced
144:13 by extreme processes near black holes
144:16 such as the heating of matter in the
144:18 accretion disc or the launching of
144:20 relative istic Jets by examining black
144:23 holes across multiple wavelengths
144:25 astronomers can gain a more
144:26 comprehensive understanding of the
144:28 physics at
144:30 play instruments like the Chandra x-ray
144:32 Observatory and the proposed Lynx x-ray
144:35 Observatory are designed to study high
144:37 energy phenomena in space offering
144:40 insights into the life cycles of black
144:42 holes and the energetic events
144:44 surrounding them Beyond new instruments
144:47 advancements in computational technology
144:49 are trans forming how scientists study
144:52 black holes supercomputers now allow
144:55 researchers to simulate complex black
144:57 hole systems including their accretion
144:59 discs magnetic fields and interactions
145:02 with surrounding
145:04 matter these simulations are crucial for
145:07 interpreting observational data as they
145:10 provide a model for how black holes are
145:11 expected to behave under various
145:14 conditions simulations have helped
145:16 scientists understand how black hole
145:18 jets are formed and what causes their
145:20 intense
145:21 emissions with the continued growth of
145:23 artificial intelligence and machine
145:25 learning researchers are also developing
145:28 new algorithms to sift through the
145:29 enormous amounts of data generated by
145:32 observatories making it easier to detect
145:34 faint signals from black holes or
145:37 identify patterns that might otherwise
145:39 go
145:39 unnoticed a major focus of future black
145:42 hole research is to gain a deeper
145:44 understanding of how black holes grow
145:46 and evolve over time black holes start
145:49 small but some grow to enormous sizes
145:52 this growth process is not well
145:53 understood especially for the super
145:55 massive black holes found at the centers
145:57 of galaxies one question that scientists
146:00 hope to answer is whether these black
146:02 holes formed directly as massive objects
146:05 in the early universe or whether they
146:07 grew over billions of years by accreting
146:09 matter and merging with other black
146:12 holes the James web Space Telescope and
146:15 other Next Generation telescopes will
146:17 enable astronomers to peer back to
146:19 earlier periods of the universe
146:21 potentially capturing images of the
146:23 earliest black holes and shedding light
146:26 on how they formed and
146:28 evolved in the coming decades new
146:31 observations and experimental evidence
146:34 May provide the answers that our
146:36 theories are looking for Missions like
146:39 the Event Horizon Explorer a proposed
146:42 project to send an array of X-ray
146:44 observatories into orbit aim to capture
146:46 high resolution images of black hole
146:48 event Horizons further unveiling the
146:51 structure and behavior of these objects
146:54 other Concepts like building a
146:56 constellation of telescopes in space
146:58 could allow scientists to study black
147:01 holes in unprecedented detail from
147:04 multiple angles creating a
147:06 three-dimensional view of their
147:07 interactions with the surrounding
147:10 universe as black hole research
147:12 continues to advance each new discovery
147:14 adds an additional piece to the puzzle
147:17 the tools at our disposal are expanding
147:19 rapidly and with these tools scientists
147:22 are poised to uncover secrets that once
147:24 seemed beyond our reach Bridging the Gap
147:27 between our understanding of the true
147:28 nature of black holes and their role in
147:31 the cosmos what sort of exciting
