ELECTROWEAK FORCE - Unified force combining the electromagnetic force and weak nuclear forces. The unification of these two forces was proposed in the 1960s by Sheldon Glashow, Steven Weinberg and Abdus Salam.
Electroweak Force
(a) The combination of the electromagnetic force and the weak nuclear force which takes place at high energy.
(b) A unification of electromagnetism and the weak nuclear force.
Theories that combine the strong and electroweak forces into one are generically known as Grand Unified Theories, or, less formally, GUTs.
Basically, around 1980 or so, theoretical physicists managed to unify the electromagnetic and weak forces into the electroweak force. This resulted in, among other things, the standard model.
(b) Class of theories that purport to reveal identities linking the strong and electroweak forces.
The aim of researchers now is to discover whether the strong force can be unified with the electroweak force in a grand unified theory (GUT).
He was awarded the 1979 Nobel Prize in Physics (with colleagues Abdus Salam and Sheldon Glashow) for combining electromagnetism and the weak force into the electroweak force.
nearly 10+25 meters (over 1 billion light-years -- for comparison, our galaxy is 100,000 light-years across) in diameter. The energy that drove this was the phase transition of the separation of the Strong Nuclear force from the ElectroWeak force.
