unified field theory
- noun a single theory that defines the interrelationships between the theories of nuclear, electromagnetic and gravitational forces
- (written as Unified Field Theory)Union of the laws governing gravitation, electromagnetic fields and atomic forces. A Unified Field Theory is an ambition of present-day physics which may be achieved within the next few years and would have large effects on thinking in cosmology. GUTs (Grand Unified Theories) are replacing unified field theory in physicists’ jargon and are close to them in meaning.
- (written as Unified-Field Theory)A theory describing a single force which would result from the unification of the four fundamental forces of nature, which are the gravitational force, the weak force, the electromagnetic force, and the strong force. Also called Grand Unified Theory.
- (written as Unified-Field Theory)A theory which describes a single force which would result from the unification of two or more of the four fundamental forces of nature. For example, that describing a single force which would result from the unification of the gravitational force and the electromagnetic force.
