# A new explanation for the nature of the superstring and the manner of its creation

In 1971 a mathematical transformation between bosons and fermions was the first attempt to the invention of supersymmetry. So the String theories that include fermionic vibrations were known as "superstring theories". In other words, Superstring theory is a theory that attempts to explain all fundamental forces of nature in one theory. It also tries to form the particles by using the supersymmetric strings that require 11 dimensions. Since its beginnings, superstring theory has developed into a broad and varied subject with connections to quantum gravity, particle and condensed matter physics, cosmology, and pure mathematics. Although Superstring theory is based on supersymmetry, but no supersymmetric particles have been discovered yet. Based on Saleh theory, photon is the smallest, the fastest, lightest and also the boundary between energy and mass, as everyone knows. On the other hand, the electron is the birthplace of the photon. If we look at the electron, we see that it has different types of motion. It revolves around itself and around the nucleus, at a fraction of the light speed. So when a photon is scattered from an electron, it takes these two rotational motions from electron in addition with its own spin. In this article we have explained the relationship between supersymmetric and photon. In addition, we have explained that how these 3 motions could cause the eleven 11 dimensions (5 + 5 + 1) that we need in superstring theory (M-theory).
