GUT (Grand Unified Theory)

A Grand Unified Theory (GUT) is a scientific idea that aims to describe the fundamental forces of nature—electromagnetism, the weak nuclear force, and the strong nuclear force—as different aspects of a single, unified force. Currently, these forces are explained separately, but GUT suggests they all merge into one at extremely high energies shortly after the Big Bang. While experimental proof is still needed, GUTs seek to deepen our understanding of how the universe's fundamental forces originated and how everything in the cosmos is interconnected at the most basic level.
