In one experiment, a photon entered one detector and that detector then indicated the slit through which a second photon passed in a double-slit experiment that was some distance away from the first detector. This experiment shows that
A) macroscopic detectors always exert actual forces on microscopic particles, even at a distance. B) it is possible for a detector to obtain complete information about a particle's simultaneous position and velocity, without causing a sudden change in the EM field. C) whenever a detector exerts an actual force on a particle, it causes the particles EM field to suddenly change. D) microscopic events are subject to Heisenberg's uncertainty principle whenever detectors are involved. E) macroscopic detectors can have non-local effects even on objects that they do not directly interact with.
