Re: Time-symmetric QM again
by Steve at 00:57 08/09/11 (Blogs::Simon)
So if I'm reading this right, one of the experiments involved taking a reading of a laser light either once or twice. And if you did it twice then the first reading was affected by the first.

So somehow the fact that you're going to actually do the second reading becomes known in advance to the particles and they respond accordingly even before the event has happened?

In which case I agree with Bruce. This is just too fucking weird. Expanded to the human scale, it would be like saying we've no free will since future events are influencing the past somehow. But, oddly, there's something comfortingly familiar about it because it gives you the feeling that all the decisions you made were the correct ones. But if you're someone who likes the idea of being in control of your decisions then perhaps not so comforting.

Strange physics.
