The unified field theory is an attempt to describe all fundamental interactions (gravity, electromagneticism, weak forces,
strong forces) between elementary particles in terms of a single theoretical framework based on the Quantum Field Theory.
So far the weak force and the electromagnetic force have been successfully united in electryweak theory, and the strong
force is described by a similar quantum field theory called Quantum Chromodynamics. However, attempts to somehow combine the strong and electroweak theories in a grand unified theory have failed, as
have attempts at a self-consistent quantum field theory of gravitation.
