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 elusive goal is to develop a set of equations that unify all known natural forces (gravitational, electromagnetic, weak, and strong).  A leading proponent of string theory has been Edward Witten of the [[Institute for Advanced Study]].
