View submission: Is there any working theory of what preceded the Big Bang?
I'd say one of the leading contender theory is "Inflation" (https://en.wikipedia.org/wiki/Inflation%5C_(cosmology[1])[2] , it's basically the idea that space underwent an exponential rapid expansion before the regular Big Bang. In fact, it's so mainstream that sometimes it's just lumped into Big Bang itself. This inflation solves a bunch of problem, including why monopoles don't just collapse the Universe, it explains why the Universe seems to uniform, and a host of other issues.

Now if you buy this paradigm in cosmology, then the next question is what happens before cosmological inflation? Cosmological inflation is typically caused by some sort of instability in one or more quantum fields, causing vacuum to decay in some intricate patterns. One very plausible extension of this is the idea of eternal inflation and multi-verse (https://en.wikipedia.org/wiki/Eternal%5C_inflation[3]). Basically the idea that the Universe is sorta like a bubble pot of hot water, with pockets of instability forming, causing inflation and creating new universe. This may have been occurring since eternity and we are merely one of infinitely many roiling and boiling bubble in this massive multi-verse soup.

Alright that’s really interesting! I’ve heard the idea of bordering universes before, is this what you mean?
