M-theory is a theory conjectured by [[Edward Witten]] of the Institute for Advanced Study, that would unify the five different superstring theories: [[Type IIA string theory]], [[Type IIB string theory]], [[Heterotic string theory]], [[SO(32) string theory]], and heterotic ''E''₈×''E''₈ string theory; all of these seemingly different string theories are simply different limits of the same underlying M-theory.  [[Edward Witten]] has used M-theory to explain a number of observed dualities, such as the T-duality, U-duality and S-duality.  The discovery of M-theory is hailed by string theorists as the second superstring revolution.

In M-theory, the fundamental constituents of the universe are membranes, or p-brane where p is the dimensionality of the membrane.  Thus the strings theorized in [[String Theory]] belongs in the class of 1 dimensional membranes, the 1-branes.
