I was thinking about multiple universes and had a few questions about current thinking.

I heard somewhere that according to some theories, our universe is just one bubble in a foam where each bubble is another universe. Did I summarise this theory correctly?

Is it an extention of M theory?

If you could travel between membranes, would you ever have to pass through one universe to get to another. (I was thinking of them as a stack of sheets) Is this where the foam concept comes in.

What is between bubbles or membranes?
