Unified field theory

In physics, a unified field theory is a type of field theory that allows all of the fundamental forces between elementary particles to be written in terms of a single field. There is no accepted unified field theory yet, and this remains an open line of research. The term was coined by Albert Einstein who attempted to unify the general theory of relativity with electromagnetism. A Theory of Everything is closely related to unified field theory, but differs by not requiring the basis of nature to be fields, and also attempts to explain all physical constants of nature.

Any theory which explains the strong nuclear force, the weak nuclear force the electromagnetic force and gravity as different aspects of the same superforce. Theorised to have been present in the universe only during the Planck time. Following this, gravity immediately became independent of the other three. These other forces continued to function as the grand unified force until later in the history of the universe , when they too separated, in stages, into the forces we know today.
