So, this thread is full of nothing.

Inflation is what leads up to the Big Bang, it correctly predicts the spectra of light we see in the CMB (can't find the image which shows Inflation vs. other theories, it's in one of Guth's MITOCW lectures)

Part of Inflation is the fact that the rate of decay of inflation is slow than the expansion, which means there should always be parts of the universe which are inflating. This, combined with the idea that seperate areas can inflate at different times, leads to the idea of bubble universes.

Basically, what we observe as the big bang may have been one of many nucleations of space and time as we know it. Our universe may be part of some larger structure which may give rise to spaces like the one we occupy.
