Grand Unified Theory (GUT) is any model in particle physics that merges the electromagnetic, weak, and strong forces (the three gauge interactions of the Standard Model) into a single force at high energies.
Learn about the attempts to describe all fundamental forces and particles in a single framework, from Einstein's general relativity to grand unified theories. Explore the concepts, evidence, and challenges of unified field theory in physics.
Apr 18, 2024 · Learn what Grand Unification means in the context of particle physics, and how it relates to the Standard Model of the three fundamental forces. Explore the history, challenges, and possibilities of unifying gravity with the other forces.

May 21, 2018 · Learn about the theoretical attempts to unify the fundamental forces of nature, such as electromagnetism, weak force, and strong force. Find out the challenges, obstacles, and key terms related to grand unified theory and quantum gravity.
Feb 20, 2022 · Attempts to show unification of the four forces are called Grand Unified Theories (GUTs) and have been partially successful, with connections proven between EM and weak forces in electroweak theory. The strong force is carried by eight proposed particles called gluons, which are intimately connected to a quantum number called color—their ...
