I've been studying EPR and such for about a month and I have a question which may be interesting or may be basic-- I can't tell. Imagine we have two correlated particles in a spin singlet state. We know that if we measure the spin of one in any particular direction, the spin of the other will be the opposite, in this same direction. My question is why this situation seems to require faster-than-light communication between the correlated particles. Imagine I take a playing card and rip it in half, mix up the two pieces, and send them to opposite sides of the room. If I look at one piece, at one end of the room, and see that its the King's head, then I know instantly that the other piece, at the other end of the room, is the King's body. Now with quantum spin we can measure in any direction in space, so we have a deck of cards of infinite size. At any direction we get one value, and at the other particle we get the opposite value. So instead of faster-than-light communication between the particles, we should really talk about a property that has an infinite domain (directions in space) mapped into two values (of spin). This property starts at the joined singlet state particles and doesn't change just because they get far apart (which is admittedly weird, but doesn't require any communication between them). If we accept this kind of property we can drop worry about faster-than-light communication between the particles, yes? Each particle has an infinite amount of information (how its spin is going to measure in any direction) and the data at the other particle is the "reverse." I have read that some Bell inequality variants rule out this sort of property (this is called a "common cause" type of explanation for the correlation). So my questions are: 1) if we accept this type of property can we reject any notion of communication between the particles, and 2) is there some variant of Bell Inequality which rules out this sort of property? Thanks.
