I wasn't being sarcastic. Honest - I made a mistake and I was apologising. I'm Sorry. Shalom Shlomo

Sorry, Vanesch. You are right. I blithely included the wacky Many Worlds interpretation of QM amongst the rest, and forgot that of course it does not suffer from the normal problems, and it answers all normal questions and doubts. I'm sorry. It's just such a wacky theory, I find it...

It's important, so let's get this clear (for some reason, this hasn't been grasped properly yet across our community)... Bell showed that QM itself formally breaks causality. ie whether QM is Classical, Copenhagen, Many Worlds, Bohmiam, etc all describe a QM that violates causality because...

I guess the dispute between us is - Is there anything in this experiment beyond our current understanding of Quantum Mechanics ? I say yes, a major hole in our knowledge is staring us in the face, and we are fools to ignore it and not grasp the opportunity. You both say no, the experiment...

I don't understand. We're spending billions of dollars on super powerful particle accelerators, to try and understand the fundamental make up of our quantum mechanical particles. And yet, the problem described here is an even more fundamental gap in our understanding, with the prize of a...

How can we experimentally measure the sought time delay between the blocking of ‎the Idler 1 beam, and the corresponding disappearance of the Signal interference ‎pattern (the cause/effect time delay) ?‎ ‎Method 1:‎ Send the Signal beams along fibre-cables (maybe once or half way around the...

Everything you said above is correct, except the last paragraph. This experiment does show that our understanding (probably of QM) is greatly lacking. We knew this before this experiment, thanks to Bell and Aspect, but this experiment adds to our lack of understanding greatly. In the 14...

Quantum Mechanics depends on the concept of simultaneous collapse of wavefunction of entangled particles at space-separated places. Relativity depends on the concept of 'no such thing as simultaneous'. In the experiment described in this thread, the conflict between the two Master Theories...

Vanesch, the experiment is pretty fully detailed at: www.google.com/url?sa=U&start=1&q=http://student.science.nus.edu.sg/~g0203645/Atomic%2520Molecular%2520and%2520Optical%2520Physi cs/Quantum%2520effects%2520in%2520one-photon%2520and%2520two-photon%2520interference.pdf&e=9707[/URL]...

Interesting analogy. But when blocking one of two slits, we understand that light already through the blocked slit continues to propagate to the detector, and interference-effects only disappear once the time taken for those waves to arrive have been reached. We have a well defined and well...

Assuming the reduced density matrix is a full and correct description of quantum mechanics - which it might not be. Either way, which is the answer ? 1, 2, 3 or 4 ? ShalomShlomo p.s.: And I wish I could change the title of this thread. FTL communication was meant to imply, as in Bell's...

Who says ? If you are you relying on Eberhard's proof, then is it valid to this case ? Aspect's experiment seems to indicate that your understanding doesn't match out what quantum reality has to offer. You have put your finger on the problem. Instantaneous for the two photons, which are at two...

Thanks. But NO on two counts. 1) Mandel has shown that the Idler detector plays no part in what occurs. It is only the theoretical threat of detection, irrespective of whether the detector is there or not, that makes the Signal interference pattern appear or disappear. 2) Bell showed...

That's not quite right. Bell showed that communication does travel faster than light, but we just can't use that random-to-random communication to piggyback any information on. Here's another URL to the same paper - See Fig 6...
