unification of forces

Unification of forces refers to the idea that the fundamental interactions in nature—gravity, electromagnetism, the weak nuclear force, and the strong nuclear force—are different aspects of a single, underlying force or framework. Physicists aim to develop a theory that combines these forces into one coherent description, especially at very high energies like those just after the Big Bang. Achieving this unification helps us understand how the universe works at its most fundamental level and could reveal a deeper connection among the forces that shape everything around us.
