But it sure is fun to think about.

Just to clarify, by definition there is only
one Universe. There is nothing outside it, there are no other universes simply because where there to be such things they would, by definition, become part of the universe. Since the universe is defined as being everything there is.
That being said, I do believe that what we observe as "the universe" is not unique. There was not just one big bang. They are going off all over the place like bubbles in a glass of soda. But from our perspective inside our own bubble (that we currently define as "the universe") that's just all we can observe, the inside of our bubble.
