Pretty much everything we know at this point says that no, the universe as we know it is not going to exist forever. Life as we know it needs a place to be and something to be made out of in order to exist.

The good news is that unless something really dramatic happens, it probably won't be for a while.

Eventually light will be slower than the expansion of the universe , so there won't be any perception of things as for us light = information

Everything else is a guess from me 👍

No. The red dwarfs will live for a trillion years. So in the deep deep future, there may be red dwarfs that form in the dead shell of galaxies that some future life could use as an energy source to an unimaginably long time.

But those will come to an end. And over the very longest of time frames the acceleration of dark energy will likely make any kind of structure impossible.

This is very simplified to aid understanding rather than be a comprehensive answer.

We don't know. So far the only place we know life exists is here on earth. We have no evidence of life anywhere else and even if we find life on a body in our solar system there is no guarantee life exists anywhere else.

Roger Penrose theory is that the universe does not last, but does spawn a new universe as the last dying gasp of the previous one in a forward "pop".

Energy from the universe will eventually cool and disapate, including energy collected in black holes, which means all life will be long gone.

Assuming the new epoch universe is able to sustain life, then it will form organically.

This is a layman's description of Penrose theory.

The heat death of the universe eventually leads to a minimally entropic state. The stretching of spacetime is the only way to reset entropy. And you're not even really resetting it, just dumping it in other causally disconnected universes.

Life, as we know it, requires an energy gradient (i.e. a way to do usable work).

The currently most likely, theorized end-of-universe scenario doesn't have that ("Heat death").

The...erm...more 'exciting' end-of-universe scenarios (Big rip, Big crunch, Big bounce, False vacuum decay, ....) are even more certain to end any life that managed to hang around until then.

But, hey, we don't know everything about the universe yet. So there may be ways of sidestepping the problem.

The Ultimate Evil is an ancient cosmic force that has for thousands of years tried to destroy Earth and all planets that contain life. After its emergence through a celestial alignment of three planets and one sun which happens every 5,000 years, but each time has been thwarted by the Fifth Element.

One possibility- the last stars run out of fuel and die off.

Another possibility- the expansion of space continues, to the point everything gets torn apart and reduced to elementary particles

Yet another- the expansion slows down to the point gravity can take over, collapsing the entire universe back to what it was before the Big Bang. (Maybe starting a new big bang?)

Short answer is that life as we know it could be sustained by the universe for a very long time -- even longer than the universe has existed so far -- but not forever.

The reality is that we just don't know. Our observations (and projections) are based on what has happened, and that might change over the billions of years. Our definition of what is "alive" will certainly change over time.

Yeah, isn't this the hypothesis about giving enough time, anything that is possible will happen? And even though it's astronomically unlikely to happen, a new universe bubbling up from a Quantum fluctuation and into an entirely new and separate universe could theoretically happen.

The total quantity of energy is fixed, space is expanding, and entropy always increases on average, so the heat death of the universe is inevitable according to all accepted theories of physics.

There may be some fun hypotheses around with new universes spawning, multiverses, and other oddities, but they're just that - hypotheses, not accepted theories.

NorthImpossible8906 t1_j6i1m6a wrote

you are getting a lot of 'no' but here is a yes.

there could be another Big Bang, and an entire and new universe created. Maybe we'll figure out how to make one ourselves, and create a lot of them, forever.

and don't worry about time, we'll have a few billion years to figure it out.

All this dieing/reborn bs. The universe recycles itself and is constantly creating/dieing/being born again. It would make no sense for a universe to “die” or reach a point of no activity. Eventually it gets consumed and recycled. We really know nothing about how vast the entire universe is and big picture stuff is just theories nothing else

Life can sustain itself if there is an energy gradient to be taken advantage of. This includes the possibility of life lasting close to the end of the universe. The point at which it takes more energy to gather resources than you get back is the slow-death line-of-no-return.

Organic life may just be a stepping stone towards metallic/silicon life. In that form life may extend greatly beyond what is possible for organics. Maybe instead of uploading one's mind to another organic body, thereby destroying the host's mind, humanity might transition to a purely robotic existence. I would be fine with that, because our bodies are so easily broken. It would also allow us to go explore the universe without the need to bring the Earth conditions along with us. The most cumbersome, and annoying aspects of a spaceship is usually biological life support. If you had a spaceship of nothing but a propellant system, a guidance system, and the means by which to charge your robotic chassi, that would be a far easier system to maintain in the void of space.

Ask yourself what does all life have in common? The transfer of energy. Why would the universe have all these methods of displacing/transferring energy if it’s end game is to die an inactive cold death? A big bang is just a lazy man’s theory. What we know of the universe is that galaxies are constantly colliding and recycling each other in this way. We have no idea how many galaxies there are, or what for that matter our own galaxy is heading towards. We don’t know if the universe stretches on forever, or if there’s boundaries. So much to know still.

It could, or it could end today. There is a hypothesis that our universe is a transient state of something else, think of a bubble in a boiling pot of water, and once that bubble floats to the top of the pot and pops. Well, no more bubble.

But there is no telling what type of time scale we are looking at, it's not worth thinking about since we will either die of old age long long before that happens or we will just blink out of existance and won't be here to worry about it anyway.

> being proved wrong

fyi, you forgot to do that part. If you tried, you'd find that there is evidence space is expanding at the current time. But that does not prove the ultimate fate of the universe, obviously. But then again, if you tried, you wouldn't have started this thread in the first place.

seriously, it's weird to see trolls like you in this sub. But hey, whatever makes you feel good inside.

You seem like a 14 yr old emotional fella-- troll, arguing whatever, i was just simply discussing and i get called these , there's problem simply with you, everyone was commenting and replying and you're the only one pissed off.
