Why do EM waves propagate forward in time rather than backward in time?
Why do EM propagate forward in time, but not backward in time? Stated differently, why does EM radiation not "ripple inwards" and collect at some point? These are perfectly possible, by time-reversal. …

Is Quantum Mechanics time-symmetric?
In physics we have the CPT-theorem which guarantees time-reversal symmetry of dynamical evolution (although in some edge cases we will also have to reverse parity and charge).
It seems clear enough …
