    Causality
AI Thread Summary
The discussion revolves around the implications for physics if individuals like Miss Cleo or Edgar Cayce could accurately predict the future. It raises questions about how such abilities would challenge the principle of causality and what areas of physics would be most impacted. Participants express uncertainty about whether knowing the future could coexist with current physical laws, suggesting that it would necessitate significant revisions to our understanding of physics. The thread ultimately faces closure due to its speculative nature, with moderators indicating it does not fit within the guidelines of skepticism or philosophy.

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.
 

Thread 'Predictions for the Nobel Prize in Physics 2025'

Similar to the 2024 thread, here I start the 2025 thread. As always it is getting increasingly difficult to predict, so I will make a list based on other article predictions. You can also leave your prediction here. Here are the predictions of 2024 that did not make it: Peter Shor, David Deutsch and all the rest of the quantum computing community (various sources) Pablo Jarrillo Herrero, Allan McDonald and Rafi Bistritzer for magic angle in twisted graphene (various sources) Christoph...

Thread 'My experience as a hostage'

I believe it was the summer of 2001 that I made a trip to Peru for my work. I was a private contractor doing automation engineering and programming for various companies, including Frito Lay. Frito had purchased a snack food plant near Lima, Peru, and sent me down to oversee the upgrades to the systems and the startup. Peru was still suffering the ills of a recent civil war and I knew it was dicey, but the money was too good to pass up. It was a long trip to Lima; about 14 hours of airtime...
