The strong nuclear force into a single theory. GUT's uniteĮlectromagnetism, the weak subnuclear interaction and String theory can potentially unified not only all theįundamental forces but the elementary particles as well. Unify the four fundamental interactions ofĮlectromagnetism, gravity, the weak subnuclear force However, theorists suspect, but do not know forĬertain, that all the fundamental forces will emergeĪll remaining forces friction, string tension, supportįorces, the forces in springs, collision forces, atomicįorces, molecular forces, etc. Strong nuclear force remain as independent, isolatedįorces. The two other fundamental forces gravity and the In the 1960's, the weak subnuclearįorce was united with electromagnetism to form theĮlectroweak theory, which was subsequently verified The electric and magnetic forces into one structureĬalled electromagnetism. In the nineteenth century, scientists were able to unify Then become manifestations of a single theoretical structure. Two seemingly different forces are unified when a Physics: The Unification of the Basic Forces What Does Unification Mean? On the Possible Discovery of the "God Particle". By the end of the next decade, physicistsĬlick here for more information. Geneva, Switzerland, should be completed around the The Large Hadronic Collider, which is being built near Since all material is made of atoms and since atomsĪre made of electrons, protons and neutrons, the "breaking" produces Particle physicists do not know how this breaking mechanism works. Generated through what-is-called "electroweak breaking," but The masses of the electron, proton and neutron are Mechanism That Makes Fundamental Mass What Is the Problem? ThereĬould also be implications for black holes.įor a more detailed discussion, click here. The marriage of these two principles wouldĬreate a new fundamental understanding of Nature. Quantum mechanics and gravity are two great pillars Smaller than an atom, however, Einstein's gravity theory TheoristsĮncounter serious difficulties when trying to constructĪ quantum gravity theory would lead to few noticeableĮffects in the macroscopic world. Incompatible with the rules of quantum mechanics. The theory of gravity as formulated by Einstein is
