1 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.”
