Victor Stenger has proposed a model of the universe consisting only of atoms, void and time reversability. I like this idea, partly because it's almost simple enough for me to understand. But I have a problem with it.
He suggests that the universe can be explained as atoms and void, as per Democritus, with the introduction of time-reversability to account for nonlocal effects. The idea is this (in my words).
Say A and B are entangled particles. Measuring the spin of A will instantaneously (from some perspective) correlate with an event at B. To explain this he introduces event C, intermediate between A and B but earlier in time. Thus, particle A emits a particle (or whatever) which travels backwards in time to C, where it interacts with a particle, emitting a particle which travels forward in time to B, arriving at the moment we make the measurement on A.
This mechanism, he says, if I understand him properly, which is unlikely, would account for all the results from QM, meaning that the universe can be explained by just atoms, void and time reversability.
However, I have difficulty understanding how a signal can find its way from A to B via C without knowing where it's going when it sets out. Could somebody clarify this issues for me?
