^^ since all interactions require fields of some sort, there are suggestions that it appears instantaneous from our frames of reference but that they are just communication by reversing the arrow of time (so an electron e+ beceomes a positron e-) , the only restriction being that you can't use it to send information/signals. which is at least comforting.

why so ? seems like nothing more than focusing of scattered particles of whatever you choose off your target, can be done with electrons on toasters, and reconstruct the image with some math.
