Web12: Grand Unified Theories. Since its earliest days, science has been on a mission to unite disparate phenomena under the umbrella of more comprehensive theories. Follow the search for a grand unified theory (GUT) that unifies the workings of quantum forces, and a theory of everything (TOE) that quantizes gravity. WebIn physical cosmology, assuming that nature is described by a Grand Unified Theory, the grand unification epoch was the period in the evolution of the early universe following …
WebGrand unified theories describe the interactions of quarks and leptons within the same theoretical structure. This gives rise to the possibility that quarks can decay to leptons and specifically that the proton can decay. Early attempts at a GUT predicted that the proton’s lifetime must be in the region of 10 32 years. In particle physics, a Grand Unified Theory (GUT) is a model in which, at high energies, the three gauge interactions of the Standard Model comprising the electromagnetic, weak, and strong forces are merged into a single force. Although this unified force has not been directly observed, many GUT models theorize its … See more Historically, the first true GUT which was based on the simple Lie group SU(5), was proposed by Howard Georgi and Sheldon Glashow in 1974. The Georgi–Glashow model was preceded by the semisimple Lie algebra See more The supposition that the electric charges of electrons and protons seem to cancel each other exactly to extreme precision is essential for the … See more The unification of forces is possible due to the energy scale dependence of force coupling parameters in quantum field theory called renormalization group "running", which allows … See more Several theories have been proposed, but none is currently universally accepted. An even more ambitious theory that includes all fundamental forces, including gravitation, is termed a See more SU(5) SU(5) is the simplest GUT.
