@freemo what definition of "time travel" would not be self-contradicting?

@mjambon

I have thought about that alot and can see a way that every framework imagined for framework can be non-contradictory with some additional characteristics.

Since you said don't answer I wont go into detail unless youa sk though. But i find it a fun thought experiment.
