    Could the big bang have been caused by the inversion/collapse of a universe wide black hole?

    It doesn't explain how "stuff" began to exist in the first place, but maybe it would explain how/why singularity big bang occurs. So basically, over hundreds of billions of years black holes across the universe suck up everything and black holes merge until there is literally nothing left for them to exert forces on causing it to invert and collapse and expelling all the matter that has been trapped in it making the "big bang" a cyclic thing.

    As good a theory as any regarding how everything comes from nothing.

    well it doesn't explain why it came into existence, though maybe combining it with M theory would explain something. Like membranes touching each other and creating energy/particles.

    Also, doesn't explain a cosmological constant. And on that note, the constant also ensures that the universe will die a heat death and that black holes won't merge together in any meaningful way.

    There are *some* cyclical universe theories that aren't totally BS, close but not totally.

    Look up "Big Crunch." :)

    That theory sounds fun but does not really make sense when you consider galaxies are moving apart from each other faster and faster.

    Also if matter from the big band was already compressed would it mostly have come out as hydrogen? Seems you would have have gotten a lot of heavier elements too.

    The Big Crunch may not end up being the way it goes, but it's an existing idea that is in-line with something that the OP said, about all the black holes in the Universe eventually merging. This goes with the idea that the expansion may eventually slow and even reverse itself. Whether or not this is going to happen, or if it's going to keep spreading out and cooling down, or if it's going to be something else, is still up for debate.




    It was dense, but also incredibly hot. It's thought that it was so hot that matter couldn't even condense out of it until it had spread out and cooled sufficiently.

    The Big Bang deals with the unfolding of spacetime, while a black hole exists within spacetime.
