Causality and Psychics

[Legion81]

I don't know if this belongs in Philosophy or Skepticism/Debunking...

I seen the section of the paper with the daily horoscopes and got to wondering: How would physics change if one of these Miss Cleo or Edgar Cayce type people were real (capable of consistently and accurately stating what was about to happen)? If someone could see the future through dreams, crystal balls, or whatever, that would violate causality.

What do you think would be the most affected area of physics? Would knowing the future even be possible without major revisions to physics?

This thread doesn't fit the Philosophy guidelines and Ivan doesn't want it in S&D either.

Closed.

Yep, we don't do whatifs in S&D. The only place this would be appropriate would be philosophy. If this is too speculative for philosophy, then there is no place for this one.
