Abstract

The leading theories suggest that in the first fractions of the second following the Big Bang, equal amounts of matter and antimatter were formed, and annihilated. Therefore, the asymmetry of matter and antimatter, and formation of the visible universe is one of the major unsolved problems in physics. Surprisingly, when the major characteristics of the cosmic matter- antimatter interactions, were compared to the biologic body- antibody system, unexpected similarities were observed. They relate to the outcomes of weak and strong interactions, their specificities, annihilation of most of the antimatter, excess of matter over antimatter, difficulty in producing antimatter, early deletion of antimatter, and the material nature of the antimatter. Based on these similarities, it is suggested that a mechanism, different from the charge- parity symmetry (CP) violation, allowed the formation and preservation of the visible universe. This hypothesis could have far reaching consequences on basic concepts in cosmology.
