How Deep Does the Multiverse Go?

StartsWithABang writes Our observable Universe is a pretty impressive entity: extending 46 billion light-years in all directions, filled with hundreds of billions of galaxies and having been around for nearly 14 billion years since the Big Bang. But what lies beyond it? Sure, there's probably more Universe just like ours that's unobservable, but what about the multiverse? Finally, a treatment that delineates the difference between the ideas that are thrown around and explains what's accepted as valid, what's treated as speculative, and what's completely unrelated to anything that could conceivably ever be observed from within our Universe.

A better analogy would also represent the space time continuum and the gravity well relative to the ant.
See if your ant is walking on a large rubber sheet, then you drop a bowling ball on the spot the ant is currently at... oh wait, the universe just made my ant 2 dimensional.
But you will notice that it is travelling much slower now...
