'Spooky Action At A Distance' Of Quantum Mechanics Directly Observed

Hmmm! I suspicious of any article by people who have to depend on a weak joint.

Is this just a subtle add for Viagra???

You're welcome. I don't see any paradoxes here. Hardy's setup is given in Fig. 1 contained in this paper by Abramov. The arms are Mach-Zehnder interferometers. That means, only the C detectors will go off, because of constructive interference. The D detectors will never go off, because that path would have destructive interference, or the particles would be annihilated and there'd be nothing to set off the detector.

I also don't believe in "weak measurements". The weak "expectation values", or "observables" are expectation values divided by an amplitude. Of what use, or meaning is that?

If one wants to ponder spooky action at a distance, consider the particulars of B meson decay, subsequent to Upsilon(4S) decay. The ϒ(4S) is composed of a bottom quark(b) and an antibottom quark (¯b). It decays as in (d) in the following fig.(and link), where q and ¯q represent up(u), or down(d) quarks and their corresponding antiparticle.

Immediately after the ϒ(4S) decays, the 2 B particles exist as a pair of flavor oscillating particles. Neither particle takes on a definite identity, until one of them decays into a definite B^{0, or +/-}, or it's antiparticle. ie. B⁰<->¯B⁰, or B⁺<->¯B^-. Then the other particle can know what it must turn into. The decay of the 2nd B particle begins, with a particular rate corresponding to the decay of one of the 4 modes given in the link. Until one of the particles decays from the flavor oscillation, the other can not know what it must turn into. By the time it happens, the particles are too far apart for light speed comms to have an effect. The 2nd particle knows instantaneously what it must decay into.

This link has some more on that.

2 in the morning -- I take it you are not in the Continental US?

I have to get ready for work, I'll look at this tonight, thanks for the link...

Cheers!

I think that you're confusing "hadrons" with "hardons".

This often happens in theoretical physics, and is known as the "Randall effect", after its originator, Lisa Randall.

Cheers!

Re: My post 44.

Speaking of "action at a distance" , that is :-)

Cheers!

"I think that you're confusing "hadrons" with "hardons". "

Wow! A true epiphany! (As well as funniest thing I've read in decades!)

I finally understand...no wonder I received some strange peer reviews back in the 60's and 70's....

Dude, you're NEXT DOOR!

If information is not lost in a black hole, then consider the information from our own duality in having been alive, but gradually dead. Two sides to an equation.

If God is good - as I believe - then sorting out such energy would seem an early step on the way to heaven, or cutting all but consciousness for those bound for hell so they might observe what they otherwise might have shared.

“If I knew God I’d be Him.” ...But I know too that by Israel, meaning to “struggle”, and islam meaning to “submit”...I’ll yet struggle, thanks.
