Thanks, that helps partially. I still fail to see what causes particles to interact with one another after being separated great distances.

In my opinion, the communication medium is hidden from normal 3d space. Good book by Michio Kaku on the subject here. Has a pretty long excerpt you can read too.

Even thought they appear separate to us, they are still part of the same entity. That is what "entanglement" means. It may turn out that, while they appear far apart in our expanded dimensions, they are still very close in some other "rolled-up" dimension. It is all very wierd, but then the real world appears to be weirder than anyone has imagined.
