What does our future hold?

-
What does the future look like?
-
How will the universe meet its end?
-
We may never be truly certain.
-
But science has begun to paint a stunning picture of how the future might unfold.
-
Let's take a journey to the end of time.
-
We will travel through time exponentially, doubling our speed every 5 seconds.
-
The vision of the future will surely evolve
as we probe for more clues. But one thing is clear:
-
The universe has only just begun.

-
"The universe becomes a cosmic boneyard, strewn with remnants of dead stars."
-
"Our Sun becomes a White Dwarf - a hot, dense, shrunken stellar corpse."
-
With no fuel left to burn,
-
a white dwarf's faint glow
-
comes from the last residual heat
-
from its extinguished furnace.
-
Looking at it from where the earth is now,
-
it would only generate the same amount of light
-
as the full moon
-
on a clear night.
-
The faint glow of white dwarfs
-
will provide the only illumination
-
in a dark and empty void
-
littered with dead stars
-
and black holes.
-
In some ways it's kind of a ghost universe
-
it's the corpses,
-
the zombie stars,
-
that will take us into the future.
-
"Over time, gravity ejects dead stars and planets from their galaxies, sending them out into the freezing void."
-
"By chance, some Brown Dwarfs collide and form accidental new stars."
-
"Colliding neutron stars puncture the darkness with ultra bright supernova."

"Any surviving life forms may find refuge around aging White Dwarfs."
-
"But in time, even the White Dwarfs will fade and die."
-
A black dwarf will be the final fate of those last stars
[Stars become Black Dwarfs]
-
White dwarfs that have become so cold,
[Stars become Black Dwarfs]
-
that they barely emit any more heat or light.
-
Black dwarfs are dark,
-
dense,
-
decaying balls of degenerate matter.
-
Little more than the ashes of stars,
-
their constituent atoms are so severely crushed
-
that black dwarfs are a million times
-
denser than our sun.
-
Stars take so long to reach this point
-
we believe there are currently
-
no black dwarfs in the universe.
-
"Any matter that fails to escape its galaxy
is sucked into a supermassive black hole at the center."
-
[Black holes swallow stray matter]
-
[Black holes swallow stray matter]
"Long dormant black holes flare up in a blaze of glory."
-
[Degenerate era]
"The rotational energy of black holes becomes the last reliable source of power for any exotic future civilizations."
-
We have a pace of life that's based
-
on the energy available to us now.
-
You could imagine living,
-
conscious systems,
-
which have a very different pace and therefore,
-
can extend out, at least,
-
a lot farther than you'd imagine otherwise.
-
You could have a living system where if,
-
it had a thought every 10 trillion years,
-
that would seem normal.
-
Ever if
-
our life dies out, one could imagine
-
at some time arbitrarily far in the future,
-
a fluctuation occurs which allows intelligent life
-
to exist again, for a little while.
-
So you might have islands in time of intelligence.

"As the expansion of the universe accelerates, it
begins to spread matter apart faster than the speed of light."

[Proton decay]
"Current theories predict that atoms themselves will begin to decay, destroying all remaining matter in the universe."
-
[Proton decay]
-
A proton, one of the fundamental building blocks
-
of atomic matter, what makes us up,
-
can just spontaneously fall apart.
-
Any material that evades the pull of a black hole
-
eventually dies away as its protons disintegrate.
-
"Proton decay is still unproven - and so this chapter of the future could look very different in light of new discoveries."
-
The matter inside black dwarf's,
-
the last matter in the universe,
-
will eventually evaporate away,
-
and be carried off into the void as radiation
-
leaving absolutely nothing behind.
-
[Black hole era]
-
With the black dwarfs gone,
[Black hole era]
-
there won't be a single atom of matter left.
[Black hole era]
-
[Black hole era]

All that will remain of our once-rich cosmos
-
will be particles of light and black holes.

"The Black Hole Era begins."

"No planets, no stars, no lingering stellar remnants for life to cling to."
-
"Yet even now, time has only begun to tick."
-
"On the scale of a human lifetime, the universe has just emerged from the womb."
-
"Cold, dark, and empty - this is how the cosmos will spend most of its life."
-
"Our universe gives life only a brief moment to shine - a haven in time, safe from its fiery birth and icy death."
-
The arrow of time creates a bright window
-
in the universe's adolescence
-
during which life is possible.
-
But it's a window that doesn't stay open for long.
-
As a fraction of the lifespan of the universe,
-
as measured from its beginning
-
to the evaporation of the last black hole,

Black holes become
-
the fundamental building block of the universe.
-
A galaxy will basically be
-
a supermassive black hole in the center,
-
with smaller black holes orbiting it.
-
Zombie galaxies filled with black holes continue to evolve.
-
They'll eat each other, and they'll get bigger,
-
and maybe they'll fall into
-
the supermassive black hole and it'll get bigger.
-
The universe will still be an exciting, dynamic place.
-
it's just that the time scales we're talking about
-
are now trillions of years,
-
instead of thousands or millions of years.
-
[Black home mergers]
"In this far flung age, black hole mergers become the main event."
-
"Some grow to enormous sizes, possibly trillions of times the mass of our sun."
-
"When they merge, they send out powerful gravity waves that resonate throughout the universe."
-
Black holes can bang on space-time like mallets on a drum.
-
And have a very characteristic song,
-
Imagine two black holes that have lived a long life together
-
At the end of their lives they're going around each other,
-
crossing thousands of kilometers in a fraction of a second.
-
As they do so,
-
they leave behind in their wake a ringing of space
-
an actual wave on space-time.
-
Space squeezes and stretches as it emanates out
-
from these black holes banging on the universe.
-
Those are the gravitational waves
-
and are literally the sounds of space ringing
-
and they will travel out from these black holes
-
at the speed of light as they ring down and coalesce into one,
-
spinning, quiet, black hole.
-
If you were standing near enough,
-
your ear would resonate
-
with the squeezing and stretching of space,
-
you would literally hear the sound.
-
Imagine a lighter black hole
-
falling into a very heavy black hole.
-
The sound you're hearing
-
is a light black hole banging
-
on space each time it gets close.
-
As it falls in, it gets faster, and it gets louder.
-
Scientists used to think black holes were immortal,
-
but even these will one day die.
-
Now we're talking about time scales of unimaginable length
-
quadrillions of years into the future.
-
On that time scale,
-
even the black holes begin to evaporate.

[Black hole evaporation]
-
They evaporate away at an increasing rate,
-
until they vanish in a gigantic explosion.
-
Quantum mechanics has allowed particles and radiation
[Black holes begin to die]
-
to escape from the ultimate prison -
-
A black hole.
-
"Black holes begin to evaporate away, erasing the last large-scale structures in the universe."
-
"As they die, they light up the darkness one by one."
-
"As the black holes slowly die off, the universe continues to expand, driven by a mysterious force we don't yet understand."
-
[Dark Energy inflates the universe]
"As the black holes slowly die off, the universe continues to expand, driven by a mysterious force we don't yet understand."
-
"This is the frontier of human knowledge - a frontier ripe for exploration and discovery."
-
Philosophers and poets have asked the question,
-
"Will the world end in fire or ice?"
-
We can now give an answer.
-
The latest evidence shows that the universe
-
is not slowing down,
-
but it's speeding up out of control.
-
And the universe, we think, will die in ice
-
trillions upon trillions of years from now.
-
Empty space itself has energy.
-
In every little cubic centimeter of space,
-
whether or not there's stuff,
-
whether or not there's particles,
-
matter, radiation, whatever...
-
there is still energy, even in the space itself.
-
And this energy, according to Einstein,
-
exerts a push on the universe.
-
What is the weird stuff that's accelerating the universe?
-
We call it 'Dark energy'.
-
And this stuff is the dominant stuff of the universe
-
almost 3/4 of the matter-energy content
-
of the universe is this dark energy
-
and we don't know what it is.
-
Dark energy, unlike matter or radiation,
-
does not dilute away, as the universe expands.
-
This has crucial implications
-
for what the universe is going to do in the future.
-
So, what will be the future of the universe?
-
Well, if the dark energy remains dominant and repulsive,
-
the universe will expand forever.
-
Faster and faster and faster with time -
-
A runaway universe.
-
70% of the energy of the universe
-
resides in empty space and we don't understand why.
-
But we do know what will happen.
-
If that energy continues to be there,
-
the universe will become cold and dark and empty.
-
That's the future as it might be.
-
We don't know because
-
we don't yet understand the nature of dark energy.
-
until we do,
-
we won't know the future,
-
we won't even understand our own origins
-
and that's why we want to know
-
and study this subject.
-
"Discovering the true nature of dark energy could change our vision of the future dramatically."
-
"If it somehow weakens over time, the universe could collapse under gravity - a 'big crunch'."
-
"Given a boost, it could tear the universe apart at the seams - a 'big rip'."
-
[Black hole era]
"Physicists increasingly suspect that there may be multiple universes beyond our own, each with their own unique laws of physics."
-
"Some would harbor the right conditions for life. Others could collapse or be ripped apart."
-
"Others sill could be far more exotic than anything we could imagine."
-
"New pieces to this puzzle are out there somewhere, waiting to be found."
-
The forecast does seem to be for
-
an ever-colder, ever-emptier universe.
-
But then of course we have to ask,
-
"Could that end lead to a new beginning?"
-
And there are ideas, whereby what actually is the end
-
of our universe, could in some sense,
-
lead to the beginning of a new one.
-
"Some speculate that there may be a way to escape our universe before entropy erases everything."
-
"We could create simulated virtual universes, or with enough energy, create another one just like our own."
-
We've worked out the mathematics,
-
the equations,
-
they seem to say that
-
if you have an atom smasher,
-
that can constrict tremendous
-
amounts of energy at a single point,
-
you can perhaps open up a gateway -
-
A 'Baby universe'
-
Facing the death of everything there is
-
this perhaps is their only possibility of escape.
-
And this also raises a very intriguing possibility,
-
sheer pure speculation of course,
-
that perhaps any universe that has intelligent life in it,
-
will create baby universes, will create 'Lifeboats',
-
and will proliferate child universes.
-
and will proliferate child universes.
[Last Black Hole evaporates]
-
[Last Black Hole evaporates]
-
So an evolution may take place among universes,
[Last Black Hole evaporates]
-
in the multiverse.
[Last Black Hole evaporates]
-
Survival of the fittest may take place.
-
So those universes which do not have intelligent life are 'Infertile',
-
they have no children.
-
But those universes that have
-
mild temperatures, stars like ours,
-
would create civilizations that could open up child universes
-
and they would then proliferate.
-
"If there is no way to escape the universe, then entropy will march on, destroying the last remaining supermassive black holes."
-
"As the last one explodes and dies, it bathes the universe in light one last time."
-
[Black Hole era]
"As the last one explodes and dies, it bathes the universe in light one last time."
-
[Last Black Hole evaporates]
"As the last one explodes and dies, it bathes the universe in light one last time."
-
THE END.
-
After an unimaginable length of time,
-
even the black holes will have evaporated,
-
and the universe will be
-
nothing but a sea of photons
-
gradually tending towards the same temperature
-
as the expansion of the universe cools them
-
towards absolute zero.
-
Once the very last remnants
-
of the very last stars
-
have finally decayed away to nothing,
-
and everything reaches the same temperature,
-
the story of the universe finally comes to an end.
