CP Violation

i believe the CP violation tries to explain the abscence of antimatter in everyday life.  Laws of symmetry to do not apply to the decaying of kaons.  Every particle of matter cannot be mirrored with a particle of antimatter or they would always destroy each other.  There is speculation as to why more matter showed up after the big bang and not more antimatter.  I am not sure either as to why this was, but am trying to understand that somehow there cannot be a mirror to all things in this universe.
