Full Title: In the quantum world, the future affects the past: Hindsight and foresight together more accurately 'predict' a quantum system’s state

In short, the big shocker in this paper: "in the quantum world time runs both backward and forward whereas in the classical world it only runs forward."

I might cite the Heisenberg Principle.

Or I might not.

I knew you were going to post that...

In the quantum world, the future predicts the past.

In a Newtonian world, hindsight is 20/20.

Where’s that darn cat?

[Smedley]

Not to sound like a know-it-all, but the future affecting the past on a quantum level is not only decades-old theory, but there are existing machines that work on this principle.

Here’s a patent application I wrote on such a device: http://www.google.com/patents/US8068740

“The answer, so obvious in the case of the murder mystery...”

Sheesh....I’m not even sure about the answer to this!

[UCANSEE2]

Maybe on the quantum level, there is no such thing as ‘time’.

Begin at about 4:20 if you are particularly impatient.

Obviously false.

“It’s not clear why in the real world, the world made up of many particles, time only goes forward and entropy always increases,” Murch said. “But many people are working on that problem and I expect it will be solved in a few years,” he said.

if you can ask that question, you’re completely in the dark.

can anything we do today cause someone else to win the 2008 and 2012 elections?

[Dalberg-Acton]

This is what passes as “science” these days?

I read this yesterday.....and tomorrow.

Is that related to me never knowing what I’m going to do even one second from now until I do it? ... :-) ...

"in the quantum world time runs both backward and forward whereas in the classical world it only runs forward."

Old news ...

[9thLife]

The particle's state is not merely unknown, but truly undefined before it is measured. The act of measurement itself that forces the particle to collapse to a definite state.

Well, then, I guess we'd pretty much have to believe whatever you told us about it, wouldn't we?

[tophat9000]

funny if you say the future effects the past

isn’t it just as logical to say past is seeing in to the probable future adjusting accordingly..

just like we do ..

we try again see what’s going to happen and plan ahead...

The probable different “futures” effects the what happens in the now.. or if you will the “past” from the future’s perspective

This is like the physicists who thus come down to multi-verse theory and parallel worlds where all things are possible on the flimsiest proof, assume aliens or advanced humans may exist or even manipulate such, then deny a God though they agree that the Big Bang exists.
