Question

Quizplus · Accepted Answer

Both a grand unified theory (GUT) and a theory of everything (TOE) aim to describe how the fundamental forces in the universe are combined and explain the interactions of everything in the universe. A GUT seeks to unify the electromagnetic, weak, and strong nuclear forces, while a TOE aims to include gravity in this unification, thus encompassing all known forces and particles.
