ScienceDaily (Mar. 4, 2009) — In quantum mechanics, a vanguard of physics where science often merges into philosophy, much of our understanding is based on conjecture and probabilities, but a group of researchers in Japan has moved one of the fundamental paradoxes in quantum mechanics into the lab for experimentation and observed some of the 'spooky action at a distance' of quantum mechanics directly,
Hardy's Paradox, the axiom that we cannot make inferences about past events that haven't been directly observed while also acknowledging that the very act of observation affects the reality we seek to unearth, poses a conundrum that quantum physicists have sought to overcome for decades. How do you observe quantum mechanics, atomic and sub-atomic systems that are so small-scale they cannot be described in classical terms, when the act of looking at them changes them permanently?

HUm.
Did you see that?
Nope? Did you? Nope.

I’ll have to read the paper. The article is very poorly worded.

Action at a distance?
Yeah.

Spooky.

Aye. Try googling "Hardy paradox" and the authors' names...?

“I’ll have to read the paper. The article is very poorly worded.”
Yes, unfortunately the author of this article does not fully understand the very interesting subject they are writing about.

I’d read about it but then if I did it would be observed and so would change... I’ll just leave it for now wntil
I know it needs changing.

Interesting that a quantum system can go back to its earlier, uncollapsed state after the measurement influence is removed. It goes “back in time” and again occupies all possible locations/modes (think I read that in a different paper referenced in the sidebar).

“they used a measurement technique that has an almost imperceptible impact on the experiment”
Almost imperceptible. If one observes, it changes the results. So we only peeked at the particles and it didn’t matter? Werner Heisenberg has a few things to say about that.
