cosmologists are likely to change their mind numerous times
Yes. :<)
On the other hand, IMO, nature recycles everything. It just may be that the cosmological scales are longer than solar lifetimes.
I suppose. Some of the mechanisms aren't too clear at this point. :<) I don't like some of the multiverse concepts - those that use the concept to handle quantum randomness - because they seem so wasteful. Yankee bias no doubt. (note that usage of "Yankee" - old frugal New Englander - has not been at all synonymous with "American" for a long time)
More-or-less independent multiverses in some higher dimensions don't bother me as much, but that is provincial; I suppose we have more surprises ahead of us as big as relativity, quantum mechanics, big bangs and accelerating expansion.
