[actually he probably can't but give him a moment to dumb it down.]
If the universe can be taken to being in a constant state of growth or inflation, then pocket universes are theoretically an expected and necessary part of that outward growth. It suggests that a single 'universe' is infinite, and therefore replicated infinitely, with each universe containing its own unique historical make-up. Imagine a world in which humans never walked upright, or one in which JFK wasn't shot -- all of these are variants on the history of the same universe, with the expectation that something in the course of that history deviated from the path with which we are expressly familiar. Does that make sense?
