I'm not creating the universe. I'm creating a model of the universe, which may or may not be true.

You can be only a modest distance away from the gravity brane, and gravity will be incredibly weak.

Physics has entered a remarkable era. Ideas that were once the realm of science fiction are now entering our theoretical — and maybe even experimental — grasp. Brand-new theoretical discoveries about extra dimensions have irreversibly changed how particle physicists, astrophysicists, and cosmologists now think about the world. The sheer number and pace of discoveries tells us that we've most likely only scratched the surface of the wondrous possibilities that lie in store. Ideas have taken on a life of their own.

Secrets of the cosmos will begin to unravel. I, for one, can't wait.

Basically, I wasn't properly socialized, so it made sense to do physics.

Sometimes models are surprisingly smart.
