In physics, the combination of two theories of particle physics into a single framework to describe all interactions of gravitation ).

The two theories, the electroweak theory and the theory of quantum chromodynamics , describe the interactions between particles in terms of the exchange of intermediary particles. The model has proved highly accurate in predicting certain interactions, but it does not explain all aspects of subatomic particles. For example, it cannot say how many particles there should be or what their masses are. The search goes on for a more complete theory, and in particular a unified field theory describing the strong , weak , and {{link=electromagnetic force">electromagnetic forces.
