B Can big bang be a part of a loop?

[anuureeett]

As a high school student, even though i haven't explored the advanced equations and ideas. I think that big bang can be a part of loop that's repeating again and again. As during big bang there was high energy and high temperature it is possible it was caused by certain situations or probably the end of the previous universe which made the new one to form. Please correct me if i am wrong. thanks

The best model for the universe suggests that its expansion will continue forever. There's no evidence that the universe will eventually contract and result in a big crunch, followed by a repeat of the Big Bang. That simplestic model does not fit the data.

There are some advanced ideas about how the universe could eventually produce a new universe, rather than dying out in a cold heat death.

There was research paper discussed on here recently that I might try to find.

Here it is (note that this is an Advanced, research-level paper). It might be useful to see that physics isn't just about having an idea. The idea has to be refined and fully expressed mathematically.

Note that it might be nonsense!
