They have calculated the end of the universe

What do you think about a research whose title says “An upper limit for the useful life of stellar remains due to the production of gravitational pairs”, how many people do you think would attract it, since this headline is about something exciting about the end of the universe.

It could perfectly be titled New Calculation to Date the End of the Universe. everything we know means that things change. If you change the headline, but the topic remains the same, because this investigation is about calculating when the end of everything will be, if everything continues doing the same thing it does, that is, if the expanding universe continues expanding infinitely, if the gas clouds continue collapsing to form stars, if the stars continue to explode, becoming black holes expanding their matter to form new stars and new planets, if the atoms continue to disintegrate or join together or form molecules.

If everything continues as it has been until now, the authors of the research have calculated when the end of the known matter in the universe would be, due to a type of radiation predicted by Stephen Hawking, according to that radiation the entire universe could end up evaporating, albeit very slowly, according to Stephen Hawking all the matter in the special universe and also the black holes may even end up evaporating.

We all evaporate, but extremely slowly, however, that ends up having an end, the proposed time period for this total evaporation of everything in the universe, according to this research, would be a trillion years, that is, 1 followed by 78 zeros.

This result, if everything continues doing the same thing it always does in the universe, but the thing is that things in the universe can change a lot, there are many topics that we do not know about complex topics such as dark energy that seems to accelerate and decelerate the expansion of the universe without us knowing for what reason or topics that we still have to work on, such as the topic of string theory, which would be a way in which scientists could predict the future of the universe much better, if we were clearer about how string theory works.

The universe has expanded for 13.8 billion years, but this might not last forever, if it continues doing what it is doing until now the end would come within a trillion years as they have calculated in this recent research, but there are other theories that say or project another completely different ending, there are several different variants, there are two most popular among astronomers and among scientists in general.

One would be the great freeze and the other would be the great rupture. The great freeze would be the expansion of the universe more and more accelerated and forever, that is, infinite, there would be no end point, however, there would come a time when each atom would be as far away from another atom as the distance that exists right now between us and the Big Bang and there would come a point when there would be no energy, nor anything, everything would be completely blurred.

This cosmological model would be explained because the universe, our universe, would be expanding towards an area called “Sintter Space”, which would be a part of space with intrinsic positive energy that could be driving the universe outward, this means that the universe would not necessarily end, but as I said, it would end up completely diluted, this is also what physicists call thermal death of the universe, because there would no longer be energy and hence the freezing.

The other option would be the great rupture, which in that case would be if that “Sintter Space” could one day stop being positive and falling into negative energy, which would reverse the direction of the universe, it would mean that the universe expands a little before reaching a maximum and then takes a turn, that would reverse the evolution of the Big Bang and break the universe, tearing it and finally there is another third option that I don't know why it is less popular lately among astronomers.

These first two are the fundamental ones, that of the great rupture and the great freeze and the other option that is not so popular lately, would be that of the great rebound, that is, the expansion could reach a certain point and then a great contraction would begin that would concentrate all the mass of the universe in a single singularity.

That singularity would rebound, like the name, the great rebound and would cause a new Big Bang, so our universe would be just a phase within a cycle of infinite universes, it is not so popular now because it is assumed that the expansion of the universe is accelerated but of course the latest findings on the expansion of the universe paint a different picture for us and that is that the expansion of the universe can change from more to less and of course until we know how dark energy works, that is, the energy that moves this expansion of the universe it will be difficult to refine which It may be the end of our universe, so it is an open topic, we still do not have an answer.
