Grand Unified Theory

Physics

A Grand Unified Theory is any model in particle physics that merges the electromagnetic, weak and strong forces of the Standard Model into a single force at high energies; although such a unified force has not been directly observed, many models theorize its existence.

Electroweak Interaction, Theories

Electroweak unification (1960s-70s) demonstrated that two of the four fundamental forces could be merged into one framework, the template later Grand Unified Theories extend to the strong force.

Precursor To

Theory of Everything, Theories

Grand Unified Theories aim to merge three of the four fundamental forces (electromagnetic, weak, strong); a full Theory of Everything would extend that unification to gravity as well.

  • Lead section (entity-description)
    A Grand Unified Theory (GUT) is any model in particle physics that merges the electromagnetic, weak, and strong forces (the three gauge interactions of the Standard Model) into a single force at high energies. Although this unified force has not been directly observed, many GUT models theorize its existence.
