Sumario:This article intends to rebuild the parity conservation under the light of quantum mechanics' 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 is an exact symmetry if the "full" Poincare group is the complete symmetry of nature. Therefore, CPT must be violated in a quantum theory of gravity, as well as by the supertheories.
