| My post apparently was from Jan 1st 1970. At 12am. I was only putting down the films I hated. Sorry for this. I'll just get my cheque book. |

| I think it's just your computer. Mine shows the right time. |

| It's fixed again. It said on the main page that date, which is seven years before I was born. I'm not Michael J Fox. I think it's probably got something to do with the amount of rice being harvested round here is messing up my internet connection and making me go back to the future. |

"JUST because we perceive time flowing in one direction, does that mean there "really is" a difference between the past and future? The old philosophical question has been re-examined by Huw Price, of the University of Sydney, in the context of quantum mechanics. He concludes that the idea that the past is not influenced by the future is an anthropocentric illusion, a "projection of our own temporal asymmetry". By allowing signals from the future to play a part in determining the outcome of quantum experiments, he can resolve all the puzzles and paradoxes of the quantum world.
This approach has a long (if not entirely respectable) history, but the implications have never been spelled out as clearly as Price does in an article to be published in the journal Mind. It is one of the curiosities of Maxwell's equations, for example, that they allow two sets of solutions for the effect of a moving electric charge, one describing an electromagnetic wave moving out from the particle into the future at the speed of light (a retarded wave) and the other describing waves from the future converging on the particle at the speed of light (advanced waves). The advanced wave solutions have been largely ignored since Maxwell developed his equations in the 19th century, but a few researchers, including Richard Feynman and Fred Hoyle, have considered the implications of taking such waves to be physically real."

It's not very nice to make fun of something just because it's a wave and moving into the future at the speed of light. It isn't politically correct. Your stock has fallen in my estimation, cb. |

Is anything in quantum physics physically real? I thought it was just a matter of finding equations to model what happens, and then calling it real on a pro tem basis? (Speaking as one with no real right to an opinion on this subject, that is) |

I'd disagree here. That's probably one of the nicer things he's called me. |
