Yesterday I asked something very similar: will photons communicate if they are on the opposite sides of Earth (or Sun). Presumably, yes, the matter between the two would be irrelevant., I think.
To isolate, I would try throwing one of the photons in a Black Hole. That would be a fascinating experiment! It would be a way to probe thenature of a black hole. Generate a stream of entangled photons, throw one pair of each into a black hole, and at a varying delay, and see whatthe detection shows. One problem might be that the photon thrown intothe black hole can never be 'detected', at least by conventional means.Would there be a detectable result? Or just random?
Or "destroy" one of them, but this is close to cheating. "Destroying" them would be akin to "detecting" them, I suspect, although without actually taking measurements of the results. Jim Bell
