M-theory - Wikipedia
网页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 at a string theory conference at the University of Southern California in 1995.
Introduction to M-theory - Wikipedia
网页M-theory aims to unify quantum mechanics with general relativity's gravitational force in a mathematically consistent way. In comparison, other theories such as loop quantum gravity are considered by physicists and researchers to be less elegant, because they posit gravity to be completely different from forces such as the electromagnetic force.
History and Properties of M-Theory - ThoughtCo
网页2019年5月31日 · M-Theory is the name for a unified version of string theory, proposed in 1995 by the physicist Edward Witten. At the time of the proposal, there were 5 variations of string theory, but Witten put forth the idea that each was a manifestation of a single underlying theory.
Why Is M-Theory the Leading Candidate for Theory of Everything?
网页2017年12月18日 · String theory (or, more technically, M-theory) is often described as the leading candidate for the theory of everything in our universe. But there’s no empirical evidence for it, or for any alternative ideas about how gravity might unify with the rest of the fundamental forces.
M-Theory - an overview | ScienceDirect Topics
网页M-theory is a limit of maximally supersymmetric quantum mechanics of N x N matrices describing DO-branes. The action of the matrix model is expressed by a N x N matrix, and the dimensionally reduced Hamiltonian is given by.
网页The claimed pivotal role of M-theory is due to the established relations to the ten dimensional supergravity theories that are low energy limits of superstring theory. The advantage of the eleven dimensional theory over its ten dimensional siblings is its uniqueness and its simplicity - it contains
M-theory - Vocab, Definition, and Must Know Facts - Fiveable
网页M-theory is a proposed unified theory in string theory that aims to reconcile the five different superstring theories by introducing an eleven-dimensional framework. It suggests that fundamental objects, such as strings and membranes, exist within this higher-dimensional space, which has profound implications for our understanding of the ...
M-theory - Vocab, Definition, and Must Know Facts - Fiveable
网页M-theory is a proposed unified theory in physics that aims to reconcile the five different string theory models into a single, comprehensive framework. It is considered a potential candidate for a theory of everything, which could unify all the fundamental forces of nature into a unified whole.
