Retrocausality
Some scientists are going to test whether reverse causality -- current events that change the past -- can occur.
Retrocausality offers an alternative explanation. Measuring one entangled particle could send a wave backward through time to the moment at which the pair was created. The signal would not need to move faster than light; it could simply retrace the first particle's path through space-time, arriving back at the spot where the two particles were emitted. There, the wave can interact with the second particle without violating relativity. "Retrocausation is a nice, simple, classical explanation for all this," Dowe says.
Right. One can only admire Mr. Dowe's calling that a "nice, simple... explanation." Of course, anything cooked up by R. Feynman and J. A. Wheeler is bound to make your brain ache.
