A grand unified theory (GUT) is a theoretical framework in physics that attempts to unify the three fundamental forces of the Standard Model—electromagnetism, the weak nuclear force, and the strong nuclear force—into a single force at high energy levels. GUTs extend beyond the Standard Model by proposing that these forces were once indistinguishable when the universe was extremely hot and dense, suggesting a deeper connection between them as part of a more comprehensive theory of everything.
congrats on reading the definition of grand unified theory. now let's actually learn it.
