This content explains the origin of the universe and life, illustrating how all matter, including humans, is fundamentally composed of elements forged in stars and recycled through cosmic and biological evolution.

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