Heat death of the universe = zero percent chance life will survive. The long term future of humanity has been revealed: Extinction. There is no other possible outcome.
Prove me wrong.

Also, how does it make you feel that all the exquisite beauty and wonder of the universe will end up as a dark, empty, cold wastedump? (pic related)

New universe to capitalize on.

Also, the thing that always bothered me about the heat death, is that matter transitions into energy, undoubtedly, but vice versa, won't energy convert back into matter at a certain point?

And what about the spontaneous creation of matter at the atomic level?

>wormholes leading to "dimensions"

lel gud bait mate.

in all seriousness though, entropy and the arrow of time dictate that all matte will eventually disperse into energy, and that energy will disperse evenly throughout the spacetime.

>>7196894
How did the big bang happen then?
All energy collected into a singularity?

And the other two questions still stand.

[Anonymous No.7196911]

>>7196840
You are right, but I don't see why it should make me feel bad, the only worse feeling than all if it ending, why would want humanity to last for an eternity? It's just seems more senseless than having an end in my opinion.

>>7196874
>As time approaches infinity
Heat death happens long before "infinity", energy is finite, expansion is not.

[Anonymous No.7196913]

>>7196903
how the big bang happened is still a mystery to me, but that's irrelevant to the question at hand. Yes, all the energy that was ever in this universe - ALL of it save perhaps for the energy contained in the energies created by virtual particle annihilations (I'm not too clear on this point) was concentrated into the singularity of the big bang.

Matter is created - and annihilated - at the subatomic level spontaneously. There is no net increase in mass at a classical level of observation.

Say we discover everything there is to know about the universe a mere billion years from now? There is no more meaningful exploration to do. You're biologically immortal and you fallen in love countless times, eventually maybe you even have your consciousness transferred into a vastly superior god-like machine/bio-computer.

Don't you think you'll eventually get bored?

[Anonymous No.7196921]

>>7196911
from what I understand of the universe at present, expansion will literally never stop. Heat death is actually the inevitable result of that fact. Full heat death - the 100% even distribution of energy across spacetime - will take very, very long. In that space of time, bizarrely unusual circumstances will arise.

[Anonymous No.7196924]

we will go extinct long before this. Some sector of society will be so heavily genetically modified normal peeps won't be able to even compare and will be reduced to mere pets to the genarchs. But before that happens well find a theory thats much better at describing everything than the big bang and it won't have such a nasty ending

[Anonymous No.7196945]

>>7196913
So, essentially, heat-death, which is still relatively new (150-ish years old), is being torn up by quantum physics, which will inevitably be torn up by an even more intensive study of matter at it's basest level?

[Anonymous No.7196951]

>>7196945
I wouldn't necessarily say "torn up;" I think that with a few small modifications it should hold true despite anything I can think of in quantum physics.

And why do you particularly care whether or not heat death is true or not? Do you have some kind of vested interest in one particular theory or another?

Anyway, for all you other folks in this thread: http://en.wikipedia.org/wiki/Heat_death_of_the_universe#Time_frame_for_heat_death

[Anonymous No.7196963]

so what if we make perfectly symmetric particle / antiparticle pairs, such that no net change in energy of the system.

we can make energy and bind it into matter; as much as we need to keep going.

[Anonymous No.7196975]

>>7196963
It would almost certainly take more energy to do that than you could create. Entropy would increase.

There is no perpetual motion machine.

[Anonymous No.7196980]

>>7196840
Yes, that is what your empirical worldview logically concludes. Life is random and meaningless and headed for heat death.

[Anonymous No.7196981]

>>7196951
>Do you have some kind of vested interest in one particular theory or another?

I think everyone has some vested interest in continuing the existence of sentient life as long as possible, so it's not surprising some people will find any limitations too gloomy to accept.

You're going to have to teach me your cosmology; all mine's ever taught me is a very logical and understandable situation in which all that is - including all energy - was bound up in the big bang.

>>7196981
Not to be too edgy or anything, but what is the point of continuing our existence? Just for shits and giggles, as a sort of competition? I mean, I understand that, actually, but it doesn't seem important enough to literally try deluding yourself about the likely outcome of a system just because you don't find the answer palatable.

it's even weirder than that, anon.

given enough time, you - literally you, exactly in every way - will exist again. If it was possible once, it is always possible, and therefore unless time stops, it is also inevitable.

We've got much more immediate global extinction concerns, however, and given that this whole board, and most of humanity is against manned space travel, it seems more likely we'll be wiped out by one of those first.

And that makes sense to you. That literally everything in the entire universe was contained in the head of a pin, which head of a pin came from nowhere, and which somehow exploded, and which somehow escaped its own gravity well.

Wait for 5th dimensional kind beings to open a wormhole near Saturn that leads us to a distant black hole that has 2 oddly illuminated planets that can support life. And fall into the black hole to gather some quantum data, and make big ships to bring humanjtt there. If that fucks up then the 5th dimensional beings will open another, so just gotta wait.

Of course people what to continue the existence of life we are mentally hardwired to have this as our primary purpose

[Anonymous No.7197935]

>>7197051
We have confirmed the existence of black holes. That singularities can exist is a very reasonable assumption. The rest is simple: it exploded and escaped its own gravity well because it had more energy in it than the gravity could contain. That is why it is still expanding to this day, and will always continue to expand.

So yeah, it makes good sense to me, and there's lots of observed data which seems to back it up. It also fits nicely with my religious beliefs, for bonus, non-rational points. I think the Big Bang is a pretty rational concept. Of course it could turn out to be wrong, but from what I remember that would require our basic understanding of the nature of this universe to change pretty drastically.

When cave men were observing the world, it was rational to assume it was flat and the center of the universe. It made sense given what they knew. I am no better than the times I live in; the most rational thing I can assume about the universe is that which my time's understanding has supplied to me, keeping in mind, of course, that I need to keep my eyes peeled for inconsistencies which might hint at greater understanding.
