Question: what was before the big bang? Answere: Lots of stuff.



If you can accept that our universe was not the first universe but was spawned by two other universes floating in what physicists call 'branes' of existence in proximity to each other and "BUMPED" into one another... ,

then our big bang beginning of our universe was as simple as a fertilized egg that grew into larger and larger existence.

a universe can be spawned in different ways, one way is from a collision of branes and another is a super massive black hole concentrating mass to a sigularity that excapes into its own space-time.

Our universe alone has super massive black holes that can create a new universe, that in turn creates its own space-time separate from ours.

Possibly our universe came from a black hole from another universe somewhere. If it did we could say that in a sense we are living inside a past black hole. Weird huh?

If on the other hand you want to go back and ask how the first universes came into being I would ask you see it as an evolution of life starting from elemental building blocks that still had an earlier existence.

If you are asking what created those earliest building blocks, then I would have to say that those elemental building blocks were just there.

thus putting us back where we started.
