Grand Unification Scale

The Grand Unification Scale is an energy level around \(10^{15}\) to \(10^{16}\) GeV where scientists believe the three fundamental forces of the Standard Model—strong, weak, and electromagnetic—may merge into a single, unified force. This concept suggests that at extremely high energies, these forces behave as one, before splitting into separate forces as the universe cools after the Big Bang. Understanding this scale helps physicists explore the conditions of the early universe and develop theories beyond current models, aiming for a deeper comprehension of the universe's fundamental structure.
