That's kind of the point I think, because photons don't 'pick' a destination point before travelling.
- jblow 13y agoFrom the perspective of their own frame, photons don't travel. They are everywhere along their path at once. From our perspective, a photon goes through A first, then B. From the photon's perspective, that is not how it is. So the concept of a photon 'picking' a destination point, or not, is mired in an assumption that isn't true (that there would even be anything to pick).
