Unified field theory coined by Albert Einstein, who attempted to unify his general theory of relativity with electromagnetism. The "Theory of Everything" and Grand Unified Theory are closely related to unified field theory, but differ by not requiring the basis of nature to be fields, and often by attempting to explain physical constants of nature. Earlier attempts based on classical physics are described in the article on classical unified field theories. The goal of a unified field theory has led to a great deal of progress for future theoretical physics and progress continues. Governed by a global event formula_1 under the universal topology,
