I have often wondered, our universe started from the Big bang theory and science has just about proven it so.

I have never heard scientist mention any thing about the possibility of maybe another big bang happening some where else deep in space, or maybe many more such happenings.

Can anyone explain the origins of the universe? I mean surely it is impossible to get EVERYTHING from NOTHING? The best analogy I can come up with is it is like being in an enormous desert, with nothing but sand all around, and finding you've baked quite a nice cake, with no ingredients, oven, or indeed power supply. Am I wrong?
