Entropy currently has no way of really being consistantly reversed. We can reverse local entropy but that only adds to the universal entropy

Because we see it everywhere? what kind of question is that

With the help of A.I we could make a new universe by then. Check out Alan Guth he talks about how to build a universe.

Well until that sci-fi concept is proven, no we cant

I just read about him, he said that it's possible to create an universe but it's impossible for two different universes to contact each other, so if we create an universe how does it helps?

You'll be long long long dead before the universe gets there

Because (AFAIK) we don't yet have any good reason to presume the universe will progress any other way.

There's a finite amount of energy in the universe, and the universe appears to be continually expanding, ergo eventually all that energy would be too far apart for meaningful heat to exist.

long story short the universe will eventually run out of fuel for new stars, this wont be for about 100 trillion years tho afaik

more like 100 million trillion trillion trillion trillion trilllion trillion years or whatever it is at the end of this timeline. https://www.youtube.com/watch?v=uD4izuDMUQA

That number seems way to high, also seem to remember a couple hundred trillion years estimated till the Universe’s heat death but will look it up

Nobody can truly know, what happens in the future.

As an example: it's possible, that we live in a simulation, thus creator exists, and may change parameters of this simulation.

The whole point of the singularity is that we cannot predict what comes after it. Scientists aren't going to consider an unpredictable event in their predictions about the heat death of the universe.

It's one model among many, but some, including heat death, hold to certain reasonable positions.

I don't know what bubble of conversations you are in for that model to be a given, but if the amount of people you've come across who discuss it in this context is less than 5 then it's probably not accurate to infer that "people" is alluding to most or all.

Because based on our current understanding of the physics of the universe, which is probably more or less correct, there is no way to stop it. It’s not an engineering problem like building a space elevator or a fusion reactor or spaceships to go to other plants. It’s a result of the fundamental laws of the universe. There is a finite amount of “fuel” available. I really recommend this video. It’s a Timelapse of the future and a real trip.

Technically we can move to a new universe if that tech ever exists

Kawawaymog t1_ittb9kc wrote

That could be possible. In which case this universe would still end in heat death. It’s also possible that we could create a new universe but have no way to travel there. Or potentially be unable to even verify that we were successful. We may even be living in such a universe right now.

“The law that entropy always increases—the Second Law of Thermodynamics—holds, I think, the supreme position among the laws of Nature. If someone points out to you that your pet theory of the universe is in disagreement with Maxwell’s equations—then so much the worse for Maxwell’s equations. If it is found to be contradicted by observation—well these experimentalists do bungle things sometimes. But if your theory is found to be against the second law of thermodynamics I can give you no hope; there is nothing for it but to collapse in deepest humiliation.” — Sir Arthur Stanley Eddington

I think the universe is eternal, and if I'm right, then it'll always be around, but even if I'm wrong, I'm sure that future technologies would be able to ensure that the universe continues forever.

Kawawaymog t1_itt7n2u wrote

Well technically you’re not wrong. The universe will be around forever. Heat death isn’t the death of the universe. It’s the death of things happening in the universe. When heat death eventually occurs it means the universe has finally cooled down to a stable state. It will remain eternal and unchanging and time will become meaningless.
