Israeli physicist named Yakir Aharonov basically agreed with Einstein about God not playing dice, and he proposed that the future is the hidden variable underlying quantum strangeness. Individual particles, such as those photons passing through the slits of the double-slit experiment, are actually influenced by what will happen to them next (i.e.,

If it is true that what interferes with each photon is other photons, then shouldn’t the interference be lessened when the photons are very sparse? Should it not cease altogether when there is only one photon passing through the apparatus at any one time?

‘The possible’ cannot interact with the real: non-existent entities cannot deflect real ones from their paths. If a photon is deflected, it must have been deflected by something, and I have called that thing a ‘shadow photon’.
