The particle is just spinning one way or the other based on what the other is doing, and you can’t know which until you look at it. And you don’t know what the one at the other end is doing (until you look at yours). There’s no ‘message’ or ‘signal’ to actually detect--it's not like it suddenly starts spinning and you can have a little alarm tell you that's happened. It always was spinning (well, it's more complicated than that as it's a quantum state so it was all Schrodinger's Cat until you looked at it, but for practical purposes it may as well always have been).This confuses the hell out of me, too. My grasp on it is incredible weak!</blockquote>
