This was beautifully animated, and really thought provoking. I'm surprised it doesn't have more views.
That was an absolutely beautiful video. Watched it the whole way through - was glued to the screen. I'd never heard the hypothesis regarding child universes before so I'll have to read about that more.
That was touching. I thought the video was near to over when the black stars cooled off and faded away, pretty great stuff.

I've always theorised that our universes start, I.E the Big Bang, was previously just another universe, that "restarted" itself persay, due to entropy.
IDK. I may be optimistic.
But I'd always think Big Bang would appear after a infinite amount of time for some reason. Expanding in an infinite amount of time might make it all rip or crunch.
Who knows.
You're not alone, the theory is called the Big Bounce.
Anyway I've always loved reading about the sheer scale of things like this. I remember I once made a post here about the CMB Cold Spot and the ramifications of it being caused by a supervoid that went something like:
A supervoid is a field in space where no galaxies exist and matter is way less frequent. The wiki article mentions that a supervoid measuring 3.6 billion light years across was theoretically in the area of the cold spot. So if you sent a spaceship from one end of the void to the other, even if you made it travel at the speed of light, there would be enough time to allow life to spontaneously develop on board, evolve, become sentient, form a civilization, and collapse to extinction several times over before their ship even had a *chance* of swiping through a galaxy.
Fun thing about voids: we're in one, which incidentally is the largest in the known universe. Roughly spherical, 2 billion light years across, the milky way being within a few hundred million ly from the middle.
These kind of videos make me realize how insignificant I and the life time I have here is. This makes me rather melancholic and unreasonably mad that I will never find out what truly is going happen to universe
Safe and sound where galaxy-eating nanites can't get us
Also another thing that is mind-boggling is that the observable universe is only a fraction of the current theorized size of the universe, which may be far, far bigger than current models even suggest. We just can't see past our cosmic horizon because the universe is expanding faster than the speed of light at that distance, relative to us. Anything beyond that point will never be observable or reachable to humans, unless faster than light travel is possible.
If you have trouble envisioning how this is even possible, just think of two galaxies that are billions of lightyears away from a common, arbitrary point between them. Space is expanding, and accelerating in its expansion, so now imagine that those galaxies have reached the point where their relative velocity to the point is 50% lightspeed. These two galaxies are now, to each other, travelling at lightspeed away from one another. They have slipped past their cosmic horizon and will never be able to see each other ever again.
I hope there are already alien civilizations that can hop through universes like the combine.
Maybe you will get to know, maybe your energy will live on and you will roam the universe for eternity with every other dead guy.
Well you can always imagine that the universe infinitely expands and retracts til yer eventually born again by the chance of all atoms aligning perfectly, after an infinite amount of tries.

Congrats, now I have existential depression
I hope facepunch is still up after the last black hole dies
I get the idea that the closer it gets to the end of this universe, the more messed up things would become, like physics being altered as this universe almost rips itself apart to be born again.
If the dark energy theory were to be true and that there is a limited amount of matter in the universe, wouldn't the total mass of dark energy become less dense? In an inordinate amount time, couldn't the repulsive force of dark energy become less and less due to the decreasing density, allowing for gravity to become the dominant force and initiate a big crunch?
Sometimes it seems to me that "disorder" is the wrong word for entropy. If anything, the state of final entropy where everything is even and equally spread out is the most ordered.
It is the most ordered system within itself, but lacks the emergent levels of order present in what we would imagine to be a beautiful galaxy. Order needn't be synonymous with redundancy, otherwise you fall into the trap of saying that that which has the least information content is the most ordered. People have disagreed back and forth, and plectics is no where near being finished in my opinion.
"TIME BECOMES MEANINGLESS"
there's something about the ending of this video that's absolutely captivating - to me at least. After spending countless trillions upon trillions of years watching the universe change and wither, even time itself, the only certainty the universe has had for its lifetime, will become irrelevant and empty - nothing will ever happen again, ever. It puts that kind of concept into perspective - after the death of the last black hole, and all cools to the same, everything will be the same, everywhere, for the rest of time. A year after that moment would be identical to a trillion - no change, no progress, no decay. It's depressing but in an incredibly interesting way.
I like this video.
