M theory/ supergravity theory has 7 higher dimensions + 4D. Many string theorists are optimistic that M-theory explains our universe's very structure and perhaps explains how other universes, if they exist, are structured as part of a greater ' multiverse'. The mathematical framework that unifies the multiple superstring theories upon that shared geometrical range is M-theory. Some superstring theories seem to come together on a shared range of geometry that, according to string theorists, is apparently the geometry of space.

The most prominent contender as a TOE is string theory converted into superstring theory with its six higher dimensions in addition to the four common dimensions ( 3D + time). This is called the search for a theory of everything (TOE).

Today's search is for a unified field theory that is quantized and that explains matter's structure, too. This tries to resolve the alleged conflict between classical physics and quantum physics by elementary units-the one classical force: gravity, and a new quantum field theory of the other three fundamental forces.Įinstein had sought a unified field theory, a single model to explain the fundamental interactions or mechanics of the universe. String theory tries to model the four known fundamental interactions- gravitation, electromagnetism, strong nuclear force, weak nuclear force-together in one theory.
