Elsewhere I note that it is not likely that time-turners would use information-theoretic meanings of ‘information’ to prevent paradoxes.
I think it’s most likely that time-turners simply cannot create causal chains where the effect precedes the cause by more than six hours. (Is it exactly one-hour increments? Which ‘hour’ exactly, is it- 1/24th of a mean solar day, or is it 33093474372000 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom at rest and 0K?)

Ultimately, I agree. The characters say that you can’t send information back more than six hours, but that’s because of the limits of their understanding. Otherwise things are too rigid. But this thread is basically premised on taking the characters’ understanding at face value.

If you’re using an information-theoretic definition of ‘causal chain’, then this is no different!

I can’t believe that we’re using the phrase “information-theoretic definition of ‘causal chain’” in a discussion about magic...
Although !Harry probably would, if he was willing to try further experimentation.
