I don't have a conceptual problem understanding the standard wave function and its exhibition of probabilistic behavior; I have a philosophical problem with it. The source knows the geometry of the experiment because it is local to and in contact with the sink. I know this is not intuitive but it is a mathematically valid statement. I have speculated that the emission/absorption event occurs when the particles are in a particular configuration; the internal configuration of the source is cyclic so it makes sense that the emission event is dependent upon the classical distance to the sink.
