Does light really “travel”? >"The question "what path does the photon take" can't be answered" -- I didn't ask that. What I was asking was does "space" come into matter at all, when talking about light/photon "traveling"? I've read about DSE and even the recent quantum eraser experiment, trying to pin down where does "space" come into it, or in other words, does space even exist for a photon? Because to me it seems that photon is emitted and some "time" later it's absorbed somewhere else. The traditional assumption that it must have traveled is what I was questioning. Is there any experiment confirming/denying that? |

Is it possible to change the path of a single photon? okay, forgive me if I think you haven't understood my question yet, but .. I understand that gravity lays out a curved path for photon to travel and so doesn't touch the photon in its path. But if you were to introduce a gravity suddenly in the path of the photon which has left the source but still hasn't reached the destination - will it change paths or go along it's previous path and any new photons will follow the changed path thereafter. |

Is it possible to change the path of a single photon? Thanks. So ..it is a new photon then. Does gravity change the path in same fashion? I'm under the impression that gravity does so without creating any "new" photons - hence the question: Can the path(the spacetime pathway it'll traverse till it reaches the destination) of a photon be changed while it's still hasn't reached the destination? |

Is it possible to change the path of a single photon? Isn't reflection/refraction involve replacing the absorbed photon with new one with a different path? |
