The multiverse is a theory that suggests our universe is not the only one, and that many universes exist parallel to each other. These distinct universes within the multiverse theory are called parallel universes. A variety of different theories lend themselves to a multiverse viewpoint.Not all physicists really believe that these universes exist.

General relativity was Einstein’s theory of gravity, published in 1915, which extended special relativity to take into account non-inertial frames of reference — areas that are accelerating with respect to each other.General relativity takes the form of field equations, describing the curvature of space-time and the distribution of matter throughout space-time.

Many physicists feel that string theory will ultimately be successful at resolving the hierarchy problem of the Standard Model of particle physics. Although it is an astounding success, the Standard Model hasn’t answered every question that physics hands to it. One of the major questions that remains is the hierarchy problem, which seeks an explanation for the diverse values that the Standard Model lets physicists work with.

For most interpretations, superstring theory requires a large number of extra space dimensions to be mathematically consistent: M-theory requires ten space dimensions. With the introduction of branes as multidimensional objects in string theory, it becomes possible to construct and imagine wildly creative geometries for space that correspond to different possible particles and forces.

In string theory, the multiverse is a theory in which our universe is not the only one; many universes exist parallel to each other. These distinct universes within the multiverse theory are called parallel universes. A variety of different theories lend themselves to a multiverse viewpoint.
In some theories, there are copies of you sitting right here right now reading this in other universes and other copies of you that are doing other things in other universes.

String theory has gone through many transformations since its origins in 1968 when it was hoped to be a model of certain types of particle collisions. It initially failed at that goal, but in the 40 years since, string theory has developed into the primary candidate for a theory of quantum gravity. It has driven major developments in mathematics, and theorists have used insights from string theory to tackle other, unexpected problems in physics.

String theory leads to some amazing (and controversial) implications. Although string theory is fascinating in its own right, what may prove to be even more intriguing are the possibilities that result from it.
Parallel universes: Some interpretations of string theory predict that our universe is not the only one.

Einstein’s theory of special relativity has had far-reaching implications, but it has left open certain questions that string theory hopes to answer. It has altered our understanding of time and space. It provides a theoretical framework that tells us how gravity works,
Einstein’s theory of special relativity created a fundamental link between space and time.

As quantum physics attempted to expand into the nucleus of the atom, new tactics were required. The quantum theory of the atomic nucleus, and the particles that make it up, is called quantum chromodynamics (QCD). String theory arose out of an attempt to explain this same behavior.
QED attempted to simplify the situation by only analyzing two aspects of the atom — the photon and the electron — which it could do by treating the nucleus as a giant, very distant object.
