Scientific paper

This article rebuilds the parity conservation under the light of Heinsenberg's uncertainty principle and the equivalence among the four space-time coordinates. The lack of equilibrium between matter and antimatter is elucidated; neutrino mass is a logical corollary of this asymmetry. Based on this new concept of parity conservation the existence of black holes is questioned. It is also found that entropy could decrease in a close quantum system. CPT would be an exact symmetry if the full Poincare group were the symmetry group of nature. Therefore, CPT must be violated if nature obeys a larger symmetry group than that of the full Poincare group. Examples of CPT violation could be found in a quantum theory of gravity, and the supertheories.
