EPIPHANY!!! XD

So I was reading The Fabric of the Cosmos at Denny's with Colin, and it was talking about string theory and about how there's another little spherical dimension at every point in spacetime where only Planck-sized things fit. I was confused about the whole thing until I was driving home... it occurred to me that the planet is like one of these dimensions in three-dimensional space: we are the Planck-sized things on it, and we have to give dimensional coordinates for where we are on the planet in addition to where we are in spacetime. THERE YOU GOOO!!!!! Understanding stuff is good.
