Quantum Theory: Is the Future Influencing the Past?
« on: July 20, 2017, 09:55:28 AM »
I will not claim I can wrap my head around this, but I'd sure like to discuss it with other members. I have my own theories about our reality, but they're probably a bit too abstract to consider unless you're open to alternative realities.


This Quantum Theory Predicts That The Future Might Be Influencing The Past

One of the weirder aspects of quantum mechanics could be explained by an equally weird idea – that causation can run backwards in time as well as forwards.

What Einstein called "spooky" action at a distance could theoretically be evidence of retrocausality, which is the particle equivalent of you getting a stomach ache today thanks to tomorrow's bad lunch.

A pair of physicists from the US and Canada took a closer look at some basic assumptions in quantum theory and decided unless we discovered time necessarily ran one way, measurements made to a particle could echo back in time as well as forward.

We all know quantum mechanics is weird. And part of that weirdness comes down to the fact that at a fundamental level, particles don't act like solid billiard balls rolling down a table, but rather like a blurry cloud of possibilities shifting around the room.

This blurry cloud comes into sharp focus when we try to measure particles, meaning we can only ever see a white ball hitting a black one into the corner pocket, and never countless white balls hitting black balls into every pocket.

There is an argument among physicists over whether that cloud of maybes represents something real, or if it's just a convenient representation.

A physicist by the name of Huw Price claimed back in 2012 that if the strange probabilities behind quantum states reflect something real, and if nothing restricts time to one direction, the black ball in that cloud of maybes could theoretically roll out of the pocket and knock the white ball.

"Critics object that there is complete time-symmetry in classical physics, and yet no apparent retrocausality. Why should the quantum world be any different?" Price wrote, paraphrasing the thoughts of most physicists.

I remember discussing string theory with someone years ago.  0400 on night shift lends itself to diverse discussions.  I know that at least one theory of time says that all time is now, so you really could have had food poisoning yesterday, from tomorrow's lunch.  We need a better example than food poisoning get though.  Too much personal experience and bad memories.
