M-theory
In mathematical physics, M-theory is a recent extension of five superstring theories, or a relatively recent theory of everything that includes the time evolution through the Big-Bang event that created our Universe. It replaces the older string theory in 10 dimensions with a P-brane theory in 11 dimensions, one time dimension and 10 spatial dimensions. The Big-Bang is hypothesized to occur in M-theory as a result of the collision of two parallel universe P-branes, each with ten spatial dimensions and one temporal dimension. Heterogeneities in the new Universe formed after the collision would be explained by wave-like fluctuations of the two colliding branes. Moreover, a unification of five previous 10D string theories would occur in this M-theory, or Master theory. Its equations may be then also unified with previous supergravity theory in 11 dimensions.

It has been said that: "The final mathematical formulation of M-theory will have to make contact with the theory of vector bundles, K-theory and noncommutative geometry."
