The Theory of Everything (TOE) is a theoretical framework in physics that aims to unify all fundamental forces of nature, including gravity, electromagnetism, and the strong and weak nuclear forces. It seeks to provide a comprehensive explanation of how these forces interact and govern the behavior of matter and energy in the universe. One of the most famous attempts at a TOE is string theory, which proposes that the basic building blocks of the universe are not point-like particles but rather tiny, vibrating strings. While a complete Theory of Everything has not yet been achieved, researchers continue to explore various approaches to bridge the gaps between quantum mechanics and general relativity.
