http://en.wikipedia.org/wiki/Theory_of_everythingA theory of everything (TOE) is a theory of theoretical physics and mathematics that fully explains and links together the four known forces under one unifying theory. Albert Einstein was the original founder of a TOE; he believed that the only task was to unify general relativity and electromagnetism. His goal was to unify the four forces: gravity, the strong nuclear force, the weak nuclear force, and the electromagnetic force.

But Einstein had a trick up his sleeve. He had already begun a piece of work that he believed would ultimately replace quantum mechanics. It would become later known as his theory of everything - it was his attempt to extend general relativity and unite the known forces in the universe.
