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?
