So, I was thinking about white holes and one theory in particular about white holes, and that is that white holes, the theoretical opposite of black holes, are each "Big Bangs". That is to say on the other side of each black hole there is created a new Universe. So, in this particular flavor of white holes theory, the Big Bang is actually the opposite end of a super massive black hole with the mass of our entire Universe.
However, if this were the case, what would explain inflation. By inflation, I mean the period of time, in the early Universe when the Universe expanded exponentially. My question is, is there some phenomenon in black holes that would account for an inflation-style expansion of space? Is there any theories that have been proposed?
