0:05 roll up everybody have you ever wondered
0:10 where everything came from did you know
0:13 that we are all made from the dust of
0:18 stars let me show you how you are
0:20 connected to the history of our universe
0:23 and invite you all on a journey through
0:26 space and [Music]
0:41 13.8 billion years to the beginning our
0:44 universe in the very first moment of
0:46 time the universe is almost impossibly
0:49 hot and crammed full of energy in one
0:52 superhot single point suddenly the
0:55 universe expanded we called this moment
1:10 within millionth of a second the
1:13 universe is transformed into a dense
1:25 the expanding universe is now a few
1:29 minutes over and energies in NZ
1:30 following the building blocks of our
1:35 modern universe electrons neutrons and protons
1:46 the universe is now 380,000 years old
1:49 the particles called electrons have
1:50 slowed down and are beginning to be
1:54 attracted to the protons each electron
1:58 carries a negative charge and each
2:03 proton has a similar but positive charge [Music]
2:08 [Music]
2:10 the opposite charges balance each other
2:13 perfectly and they become the most
2:16 important couple in the history of the
2:28 electrons also caught by pairs of
2:30 protons and neutrons completing the
2:39 [Music]
2:42 atoms are really really small but each
2:45 one has a tiny amount of mass so every
2:48 atoms gravity is gently almost
2:50 imperceptibly pulley
2:58 as more and more atoms are gathered
3:01 together they form into gigantic
3:02 spinning clouds [Music]
3:11 [Music]
3:14 the galaxy 2 issue
3:17 spots appear deep inside these new
3:20 lights signal the birth of the first
3:32 these first stars were huge much bigger
3:35 than modern stars like the Sun this one
3:38 is so big it could swallow our entire
3:39 solar system [Music]
4:22 a super movers compute the last stage in
4:24 the element building process within
4:28 these giant explosions heavier rarer
4:45 [Music]
4:49 over billions of years debris expended
4:51 Stars slowly collects together into
4:56 giant clouds still mostly hydrogen now
5:00 peppered with a mix of heavier atoms we
5:09 this one is so big that it could contain
5:11 our solar system hundreds of billions of
5:15 times over deep inside these pillars
5:24 something is happening this time disk of
5:29 gases molecules metals and dust
5:33 since its center [Music]
5:38 [Applause]
5:40 gravity's pulling his molecules into
6:04 already a billion years ago for over
6:07 hundred nine years leftover dust lots of
6:10 first gases relentlessly bombard the
6:14 young planet each impact melting the
6:16 surface and filling the atmosphere with
6:19 molecules of carbon dioxide methane and
6:27 ammonia eventually unpacked slow down
6:31 and the surface begins to cool the steam
6:34 in the atmosphere turns to liquid and it
6:41 it rains for thousands and thousands of
6:44 years eventually covering the whole
7:04 water heated by the molten rock the
7:06 Earth's mantle bursts through vents in
7:09 the Earth's crust dissolving molecules
7:12 along the way as it beats the cool water
7:15 of the ocean these minerals are
7:19 deposited forming towers as the
7:21 molecular mixture passes through the
7:24 mineral-rich chambers they start to form
7:26 the molecules we call the building
7:31 blocks of life perhaps it was inside a
7:33 vent like this following hundreds of
7:35 millions of years of chance interactions
7:38 that molecules formed the first life in
7:44 the shape of cells some cells began to
7:47 work with and for groups until they had
7:50 become the first multi-celled organisms
7:53 over many many generations they're
7:55 formed slowly changed some of the
7:58 original microscopic molecule factories
8:02 had evolved into simple worms it wasn't
8:04 long before the worms evolved into
8:08 primitive fish using iron in blood cells
8:10 to capture oxygen and calcium to build bones
8:11 bones
8:14 fish continued to evolve and dominates
8:19 the oceans of the time the molecules and
8:21 atoms are constantly being recycled and
8:23 modified as they passed from one living
8:26 thing to another above the riveter
8:29 plants and giant insects to go with the
8:32 land but they were soon followed by fish
8:35 that had evolved the ability to crawl
8:37 out of the sea and to breathe the
8:41 oxygen-rich air these oxygen breathers
8:45 evolved into reptiles which became the
8:48 dinosaurs and for over a hundred million
8:51 years dinosaurs dominated the earth the
9:01 Masters of molecules and giant impact
9:03 changed the environments so rapidly that
9:05 many forms of life were unable to
9:09 survive the age of the dinosaurs came to
9:14 an end but some species did survive with
9:17 the dinosaurs gone mammals evolved to
9:20 take their place as the new top Adam
9:23 organizes through the process of natural
9:25 selection they adapted to new habitats a
9:28 species died off in new ones flourished
9:30 a tree of life mapped out to the
9:33 generations then millions of years later
9:34 on a distant branch of the family tree
9:37 there drew a new branch of mammals the
9:42 Apes many many generations later on a
9:44 twig from this branch there stood some
9:47 very strange leaves these Apes were
9:49 strange because their atoms had formed
9:51 brains that didn't just think simple
9:53 thoughts like I'm home
9:55 but complex ones like what we wound off
9:58 and where did it all come from
10:01 they have been finding out the answers
10:07 ever since we have gone on a journey to
10:09 discover what we are made of where it
10:14 all came from we are all made from stars [Music]
