Hello! I read that natural processes are invariant under CPT (based on some theorem) and that CP violation was observed experimentally. So this would mean that there are processes that are violated under time reversal. However, based on Noether theorem, this would mean that the energy is not conserved in these kind of processes, but I read many times that it has been no process in which the conservation of energy to be violated. Can someone explain this to me and tell me where is the flaw in my logic? Thank you!
