Earlier this century, some very strong evidence arrived showing that there was a Universe before the Big Bang, demonstrating that the Big Bang wasn’t truly the start of it all.
I grabbed this from the heading of the article.
I’ve often admitted, empirically and rationally, this universe could have formed as the result of some process in a previous universe, and in the heat death of this universe some QM fluctuation can trigger recombination and off it goes again.
The thing though, is that there will never be an infinite number of future events or universes. Which raises a curious question about the past, when does an infinite regress begin to look like the future and not the past? Horror vacui?
And yet, the immediate effect of an uncaused cause will appear to come from nothing.
