Physics. M-theory. This idea is the unique supersymmetric theory in 11 dimensions (11D), with its low-entropy matter content and interactions fully determined, and can be obtained as the strong coupling limit of type IIA string theory because a new dimension of space emerges[clarification needed] as the coupling constant increases.
In the early 1990s, it was shown that the various superstring theories were related by dualities which allow the description of an object in one super string theory to be related to the description of a different object in another super string theory. These relationships imply that each of the super string theories is a different aspect of a single underlying theory, proposed by Witten, and named "M-theory".
Originally the letter M in M-theory was taken from membrane, a construct designed to generalize the strings of string theory. String lectures. Athene's Theory of Everything. Chaostheory.
