What is Superstring Theory?
Superstring theory is an effort to find an answer for all of the atoms and cardinal forces of nature in one hypothesis by molding them as oscillations of tiny supersymmetric strings. Superstring theory is a stenography for supersymmetric string theory because contrary to bosonic string theory, it's the adaptation of string theory that contains fermions and supersymmetry.
Physicist Brian Greene gives a short explanation of superstring theory, a concept that minuscule strands of energy vibrating in 11 dimensions create every particle and force in the universe.
