Dr Chinese has an admirable exposition of Bell's Inequality, here: http://www.drchinese.com/Bells_Theorem.htm From this it appears (and please correct me if I am wrong) that a pair of entangled particles each have opposite spin BUT this spin is NOT a hidden value waiting to be revealed by measurement but is intrinsically undecided until the point of measurement. Indeed, I suspect that the question "what is the spin and position and momentum of a particle" is a meaningless question. Rather, perhaps, like asking whether a coin reads "heads" or "tails" when it is rotating in the air when you are deciding who will bat first in cricket (sorry, I'm English). It will not read either and the question is meaningless until you catch it which forces it to decide. No analogy is accurate but hopefully this may help somebody (it helps me) So, you have two entangled particles which you have pushed hundreds of miles apart, and you force one of them to reveal its spin. Instantaneously (at least 10,000 times faster than the speed of light anyway according to Wikipedia) the other particle will be found to have the opposite spin if you care to check it. Presumably the experiment is done by using two ultra accurate clocks - you force one particle then the other one a minute fraction of time later. You cannot use this to send information but clearly it is an amazing event (at least, it is to me) and seems to strike at the very basis of our (at least, my) understanding of the universe. In case you don't think this is amazing it appears that somehow a particle has told its colleague hundreds of miles away "I have just decided to read 'heads' so you will have to read 'tails'. I could equally well have decided to read 'tails' in which case you would have had to read 'heads' ". Although we cannot use this fact to send information, it seems to me that information has been sent from one particle to the other but how? Maybe through another dimension of some kind in which they are still touching? Accordingly, I would expect an "explanation" to have profound implications and to be part of a TOE or GUT. Or maybe I am missing something? Anyway, to my question, Dr Chinese states "Research continues on understanding of the true nature of particle entanglement". Could Dr Chinese or any other member(s) explain the current state of thinking in terms that non specialists can understand?
