Big Freeze (Heat death) vs Big Crunch

What's more likely and are there any other possible fates of the universe?

>> No.7226741

>>7226731

Big rip.
I'd like to believe in the Big Crunch, because muh closed universe, but things far away are moving away faster. And I'll always take facts over feelings.

Big Crunch theory implies concedes with first law of thermodynamics. It means there's a chance we'll all live again, countless ages from now. Since we'll be dead, we won't experience all the time between our death and second incarnation. However, things are looking grim.

Couldn't random microscopic fluctuations eventually start another big bang in our universe down the line in the heat death scenario? Those will continue in entropy.

>> No.7226770

>>7226731
There's overwhelming evidence in the anisotropies found in the CMB that leads to the Big Chill as the fate of the universe.

>>7226762
In the heat death scenario, matter is too far away from other matter to meaningfully interact

If energy in space is accelerating matter apart, couldn't it be used to bring it back together in some way?

>> No.7226782

>>7226770
Well that's very disappointing.

At least we have dogs.

Future humans will have some weird not-dog animal. Bunch of faggots.

What a glorious time to be alive.

Not sure what you're saying here. There is something driving matter apart on very large scales (galaxies). The atoms in ourselves, for example, do not experience this force. Eventually, they will though. This is due to the fact that this force is distributed smoothly through space, which is important due to the fact that our universe is expanding, so is the amount of energy propelling this expansion.

Big Freeze is not the same as heat death

>> No.7226813

>>7226806

What if what is propelling our universe apart not energy at all?
Sure, it takes energy to move matter through space, but it can be speculated that it's not matter that's moving through space. It's that space itself is expanding instead.
We don't know how to expand space, though we do know some of the properties which causes it to bend. I suspect that whatever it is, is invisible to the naked eye.

>> No.7226821

>>7226813
It's called dark energy. So yes, not really energy, but also not NOT energy. We don't really know what it is. And yes, space itself is expanding.

Yeah it is

Theoretical physics grad student here. Has anyone else experienced the utter transcendental existential dread caused by the knowledge that current cosmological evidence overwhelmingly supports an oncoming eternity of nothingness for all of existence? If so, how do you deal with it? I try to enjoy life as much as I can when not whiling away doing problem sets but it's almost always there, gnawing at me ;_;

PS sorry if I just infected you.

>> No.7226848

>>7226843
How come you think that is so much more daunting than the fact that you will be gone long, long before that? You will be dead, so why do you care? Honestly curious

It's just like it was before you were conceived. You were dead already, for near-eternity. It wasn't so bad.

Does it matter that everything is moving away if the sum of all the natural numbers is -1/12?

I didn't say I did, but to me they feel as being on equal footing, except one applies to the entire universe. I guess maybe deep down I'm still rooting for immortality and this shit is ruining it for me.

Yeah, I have. I got over it when I was maybe fourteen. I guess just quit crying over it, and keep going about your life like you should.

And as an antiphon to your needlessly intricate articulation, cordially pay your regards to pic related.

Humanity must defeat entropy. It must be reversed, or stopped. How can that be accomplished? What if we leave this universe and find one that doesn't erode?
