The Duality of Time Theory

There is currently no complete quantum theory of the remaining fundamental force of gravity. Many of the proposed theories to describe gravity as a Quantum Field Theory postulate the existence of a graviton particle that mediates the gravitational force. Presumably, the as yet unknown correct quantum field-theoretic treatment of the gravitational field will behave like Einstein’s general theory of relativity in the low-energy limit. Quantum field theory of the fundamental forces itself has been postulated to be the low-energy effective field theory limit of a more fundamental theory such as super-Strings Theory.
