The Theory of Everything (TOE) is a theoretical framework in physics that aims to unify all fundamental forces of nature into a single, comprehensive model. It seeks to connect the general relativity, which describes gravity, with quantum mechanics, which explains the behavior of particles at the smallest scales. A successful TOE would provide a deeper understanding of the universe's workings. Many physicists believe that a TOE could help explain phenomena such as black holes and the Big Bang. Various approaches, including string theory and loop quantum gravity, are being explored to achieve this unification, but a complete and widely accepted theory has yet to be established.
