'''String theory''' (or super-string theory when coupled with [[Supersymmetry]]) is a class of models in [[theoretical physics]] which replace zero-dimensional points (particles) in four-dimensional spacetime with one-dimensional strings in an eleven-dimensional spacetime as the fundamental building block of the universe. The main goal of string theory is to combine quantum mechanics and general relativity into a single, unified theory. | '''String theory''' (or super-string theory when coupled with [[Supersymmetry]]) is a class of models in [[theoretical physics]] which replace zero-dimensional points (particles) in four-dimensional spacetime with one-dimensional strings in an eleven-dimensional spacetime as the fundamental building block of the universe.
