M-Theory was a solution proposed for the unknown theory of everything which would combine all five superstring theories and 11-dimensional supergravity together. According to Dr. Edward Witten, who proposed the theory, mathematical tools which have yet to be invented are needed in order to fully understand it. Edward Witten, PhD (b. 1951 CE d. 2062 CE) was a Twenty-first Century mathematical physicist who introduced M-theory in 1995 CE. He proposed a unification of five superstring theories and the quantum mechanical theory of gravity – 11-dimensional supergravity. Superstring/M-theory was a promising candidate to be the unifying theory for the four fundamental physical interactions (gravity, electromagnetism, strong and weak nuclear) and provides a fundamental link between quantum mechani
