M-theory is a theory in physics that unifies all consistent versions of superstring theory. Edward Witten first conjectured the existence of such a theory...

non-technical terms, M-theory presents an idea about the basic substance of the universe. Although a complete mathematical formulation of M-theory is not known...

all consistent versions of string theory are subsumed in a single framework known as M-theory. Studies of string theory have also yielded a number of results...

Some other multiverse concepts include twin-world models, cyclic theories, M-theory, and black-hole cosmology. The anthropic principle suggests that the...

A theory of everything (TOE), final theory, ultimate theory, unified field theory, or master theory is a hypothetical, singular, all-encompassing, coherent...

superstring theories (Type I, Type IIA, Type IIB, HO and HE) are regarded as different limits of a single theory tentatively called M-theory. One of the...
