String theory is an active research theory in particle physics that attempts to reconcile quantum mechanics and general relativity. It is a contender for the theory of everything (TOE), a manner of describing the known fundamental forces and matter in a mathematically complete system. The theory has yet to make testable experimental predictions, leading some to claim that it cannot be considered a part of science.
