Imagine this problem:

We now live in the Stelliferous era. There are two possible scenarios for the future of our universe- Big Freeze and Big Crunch. Well, most of the observations and data are implicating that Big Crunch is redundant, so it seems most reasonable to go like this in the future: Degenerate era, Black hole era, Dark era – the Big Freeze scenario. For the sake of this argument, lets pretend that we are in the Dark era, and that we can wait infinite amount of time. What do you think, will we witness some quantum transition and reincarnation of the universe? I think that this is possible without some heavy violations of the laws of nature. Then it would be like this : Big Bang.....Big Freeze....Big Bang....Big Freeze... infinite number of times. One universe, but in infinite number of oscillations. No Multiverse, but permanent transformations of our universe?

In this situation, things would become very interesting!

Best wishes!
