In GUTs, the electromagnetic force and weak nuclear force were the first to separate; thencame gravity.

Question

Quizplus · Accepted Answer

In GUTs, the strong nuclear force and the electroweak force (combination of electromagnetic and weak nuclear force) separate first. Gravity does not separate until the unification scale, which is much higher than the energy scales at which the other forces separate in GUTs. In GUTs, the strong nuclear force and the electroweak force (which includes electromagnetic and weak forces) were the first to separate, then gravity would potentially emerge at much higher energies.
