Does the string theory really require that our universe is just one slice in gazillions (or infinite?) other slices with different dimensions and such?...whats this theory called?
According to several famous versions of stringy physics we do. There is the Randall Sundrum model in which we live in a four dimensional brane that is the boundary or edge of a higher dimensional brane. Some of the puzzles of physics, like why gravity is so much weaker than the other forces, are explained by this modelGold Barz said:are "branes" = universes...i mean do we live in some kind of brane?
