Main Page | See live article | Alphabetical index The Grand Unification Energy is the energy level above which, it is believed, the electromagnetic force, weak force, and strong force become indistinguishable from each other. The electromagnetic and weak forces become indistinguishable at a lower energy level, forming the electroweak force, and gravitational force requires an even higher energy level to unify with the other three. Grand Unified Theories (GUTs) attempt to make predictions regarding the Grand Unification Energy and the characteristics of the three unified forces. One estimate of the Grand Unification Energy is at least a thousand million million million GeV, or . (The most powerful colliders ever designed could go up to a few thousand GeV) This article is a stub. You can help Wikipedia by fixing it. This article is from Wikipedia.
