Grand Unified Theory (GUT) aims to unify the three fundamental forces of the Standard Model: electromagnetic, weak, and strong nuclear forces. It proposes that these forces were once a single force in the early universe.

GUTs predict that at high energy levels, the electromagnetic, weak, and strong nuclear forces merge into a single force.
One of the primary motivations for GUTs is to explain why protons do not decay.
Most GUT models include predictions about proton decay, although it has not been observed experimentally.
The unification scale for GUTs is typically around $10^{16}$ GeV.
GUTs do not include gravity; incorporating gravity requires a theory of everything (TOE), such as string theory.
