I T-symmetry and conservation of energy

  1. Aug 5, 2016 #1
    I read that since CPT-symmetry is not broken, and CP-symmetry is, T-symmetry must also be broken, is that correct?

    If that is correct, does that mean that energy isn't conserved?

    T is not symmetric under reversal but still symmetric homogeneous under translations. So by Noether's theorem, energy is conserved.
