Do these both violate classical 2nd principle of thermodynamics? Seems like reverse time would require decreased entropy but what do I know?
Just a thought before leaving for the evening..something I heard on nova..

Huh? No, neither QM nor relativity violate thermodynamics.

Entropy is the only attribute I know of that requires the arrow of time. Go backwards, reverse entropy, yes. This does not conflict with thermodynamics.

If 2nd law applies then added energy, a lot of it I would guess, would be required. Thanks both for helping clear my thinking.
