The unified field theory


The unified field theory is for modern physics the most important problem. This theory says that after the Big Bang only one unified power has existed. This GUT-Power (Grand Unified Theory) was divided into four fundamental powers.
The four fundamental powers


strong power range: 10^-15 m between quarks
electromagnetic power range: infinite between charged particles
weak power range: 10^-15 m between leptons (neutrinos, elecrons)
gravity range: infinite between all particles


Today we try to bring the four powers together. It has been discovered that a symmetry has existed between the electromagnetic power and the weak power which has broken. It is important to know that the W+-, the W-- and the Z0-particles are the exchangeparticles of the weak power. In our universe there is the higgs field, which unifieds with the field of the weak power. With high energy it is possible to destroy the higgs field and the exchangeparticles of the weak power are then free, they behave like photons and do not differ from them. For this discovery S. Glashow, S. Weinberg and A. Salam got the noble price. In an experiment in the CERN (Conseil Européenne pour la Recherche Nucléaire), in the proton-antiproton-collider this particles were found and so the electricalweak power was proofed. Now phycisists work to find a connection between the electroweak power and the strong power.
