Abstract: Time/CPT symmetry is at heart of many models of physics, like unitary evolution in quantum mechanics, or Lagrangian formalism we use from classical mechanics, electromagnetism, up to general relativity and quantum field theories. However, this symmetry is quite nonintuitive, very difficult to really accept – mainly due to thermodynamical counterarguments. Let us try to discuss these arguments, especially experiment-based. I will present some for us to discuss (adding more is welcomed), for example: Wheeler’s, delayed choice quantum eraser (DCQE), “asking photons where they have been”, “photonic quantum routers”, Shor algorithm as more sophisticated DCQE, also: Anderson localization (starting with rho~sin^2 in [0,1]), Born rule, Bell violation.
