Many solemn nights
Blond moon, we stand and marvel...
Sleeping our noons away.
- Matsunaga Teitoku

As primeval man watched the moon in the night sky,

it became to him an object of curiosity.

In the legend he tells the story of an old man,

who while digging,

discovered a small shining object.

As he held it in his hand

it grew and grew-

and finally escaped into the sky and become -

The Moon.

This is the Moon,

that saw life begin on Earth,

millions of years ago.

"The Moon has a secret."

"Written in its rocks is the story of a spectacular past."

"Where did it come from?"

"What role has it played in the story of life?"

"For generations we have looked up and wondered."

"Only now is the truth being revealed."

"Forget what you know."

"It's time to see the Moon in a new light."

THE SECRET HISTORY OF THE MOON

"Moon rocks are like pages
from an ancient history book."

"Fifty years ago, rock samples from Apollo
gave us our first glimpse at the Moon's epic history."

"Fifty years ago, rock samples from Apollo
gave us our first glimpse at the Moon's epic history."
Stones from across the night.

Stones from across the night.

By making ourselves very small,

perhaps we will see what this rocks has seen,

and remember back those billions of years.

Over decades now,

Geochemists have been measuring

lunar samples and earth samples-

[Voice of: Dr. Sarah T. Stewart ]
lunar samples and earth samples-

[Voice of: Dr. Sarah T. Stewart ]
and found that the chemical signatures of the two

and found that the chemical signatures of the two

are identical in a very special way.

That the elemental isotopes of the two bodies are identical.

"We also found that volatile elements
have been somehow vaporized away."

"These clues seem to suggest that Earth and Moon
share a common origin - a violent one."

"What story best fits the evidence?"

"Many ideas have been proposed.
But one theory has reigned supreme for decades."

-{ Giant Impact Hypothesis }-

"4.5 billion years ago, our solar system was a crowded place."

"As many as 20 rocky protoplanets circled the sun,
each competing for dominance."

"As these protoplanets collided and fused,
larger planets took shape, among them the moonless Earth."

"80 million years after it had formed,
Earth had one final, tremendous blow in waiting."

"Enter Theia:
A smaller rival planet in a fateful collision course."

"To any observer on the Earth, the sight would have been terrifying."

"Upon impact, Theia is completely obliterated,
ripping off Earth's outer layers and leaving it a molten ball."

"Earth becomes engulfed by a thick atmosphere of vaporized rock."

"Over the span of ~100 years, the orbiting disk of debris
cools and condenses into a young, molten Moon."

The theory can explain

so many things about the Moon,

but it has a huge flaw -

it predicts that the Moon is mostly made

from the Mars sized planet.

That the Earth and the Moon are made from different materials.

But that's not what we see.

The Earth and the Moon are actually like identical twins.

The genetic code of planets

is writied on the isotopes of the elements.

The Earth and Moon have identical isotopes,

that means that the Earth and Moon

are made from the same materials.

"Could the long reigning theory be wrong?"

"To reconcile the evidence, scientists have proposed some mind-blowing ideas."

-{ Georeactor Hypothesis }-

"Early in Earth's history, radioactive elements like uranium
would have been much more abundant in its interior."

"These elements could have become concentrated
under Earth's surface due to centrifugal force."

"The result: a massive underground nuclear explosion."

"Under this theory, material ejected from this explosion
slowly coalesced into the Moon we know today."

"This would easily explain the similarities between Earth and Moon."

"However dramatic, the theory has its own complications."

"Some doubt that uranium could have been concentrated enough
to produce such a powerful eruption."

"Perhaps we need to change our perspective."

"Perhaps we need to change our perspective."
What do you do when faced with the unknown?

What do you do when faced with the unknown?

Question everything...

"After re-examining the giant impact idea,
a fascinating new theory is beginning to emerge."

-{ Synestia Hypothesis }-

-{ Synestia Hypothesis }-
We were making the mistake

-{ Synestia Hypothesis }-
of thinking that a planet

-{ Synestia Hypothesis }-
would always look like a planet.

-{ Synestia Hypothesis }-

The giant impact

was making something completely new.

"In this new theory, Earth was hit so hard that it was
completely pulverized into a torus of liquid rock: a "synestia"."

The energy from the impact-

vaporizes the surface, the water, the atmosphere

and mixes all of the gases together

just in few hours.

The Earth would have been like Jupiter,

there's nothing to stand on.

A synestia gives us a new way

to solve the problem of the origin of the Moon.

The Moon grew from magma rain

that condensed out of the rock vapor.

The Moon could have orbited inside the synestia

for years,

hidden from view.

Revealed by the synestia cooling and shrinking,

inside of its orbit.

The synestia turns into Earth

only after cooling for hundreds of years longer.

The Moon special connection to Earth

is because the Moon formed inside the Earth

when Earth was a synestia.

Synestias have been created throughout the Universe.

We only just realized that

by finding them into our imagination.

"The synestia theory is still unproven. But it brings us
closer than ever to cracking the secret of the Moon's origin."

"The Moon holds its secrets close.
What else could it be hiding?"

"The Moon holds its secrets close.
What else could it be hiding?"
What else am I missing?

"The Moon holds its secrets close.
What else could it be hiding?"

"The Moon holds its secrets close.
What else could it be hiding?"
What is hidden from my view by my own assumptions?

What is hidden from my view by my own assumptions?

"On its way to becoming the barren rock we know today,
it may have once held liquid water - and even life."

"Twice in its history, lunar volcanism brought huge amounts
of water vapor from the Moon's interior to the surface."

"These massive outgassings could have led to
surface water and a lunar atmosphere, 4 to 3.5 billion years ago."

"Imagine swimming in a pool of Moon water,
looking up at early Earth as life evolved."

"In theory, microorganisms from Earth could have arrived
via asteroid impact and settled in these waters."

"But if there was ever life on the Moon, it was not to last."

"Over time, any surface water would have dried up,
and almost all of its atmosphere lost to space."

"But the Moon would leave its mark on life
in a different, more profound way."

"It may even be the reason we exist at all."

"As Earth evolved, the Moon's gravity stabilized its tilt,
protecting life from extreme swings in climate."

"Life on Earth would be very different,
or even nonexistent, without our Moon."

"To know its history is to know our own.
Our roots are connected."

"We have learned much.
But mysteries still remain."

"To know the full story, we have to go back."

"More pages of the Moon's history are waiting for us."

"Whether we return or not is up to us."

"It will be waiting for us, like it always has."
