@scottbaker8528 If I'm understanding Smith correctly - the properties of the two particles are joined in each distinct possible universe, so that when the wave function collapses in your local space, that selects a specific set of universes where that choice of the property is true and that is necessarily the same universe where the other particle has the opposite property. The only thing traveling faster than light, so to speak, is the elimination of a set of possible universes where the wave would have collapsed differently. Not sure I agree, but that's the way I read his explanation.
