Oooh. Fun nerdy terminology!

Multiple universes nor extra dimensions surprise me completely. I mean, there must be space outside of the universe, an infinite void that may be populated with other universes. And extra spatial dimensions are impossible to physically comprehend, but I'm sure there are more than three.

What I'm interested in is if this is proof of the Big Bang.

EDIT: Do the extra dimensions mean spatial dimensions or am I making an ass of myself?

Yes spatial dimensions (although some theoretical physicists are suggesting that there maybe 2 time dimensions).

These extra dimensions are likely to be 'curled up' into a ball like shape, with a diameter of around the Planck Length (roughly 1.6*10^-35 meters).
