Brane cosmology refers to several theories in particle physics and cosmology related to string theory, superstring theory and M-theory. == Brane and bulk == The central idea is that the visible, four-dimensional spacetime is restricted to a brane inside a higher-dimensional space, called the "bulk" (also known as "hyperspace").
