But only after a decision was made by a person to create the photon? Because otherwise that would be pretty spooky.
Yeah, it's only once the photons in front of it could already have gotten there, so it's like photons from the tail end of the pulse are catching up to the front as it emerges, even though they haven't even entered the cloud yet.
Yeah that's pretty weird but nobody could ever notice unless they knew what to look for. Now, if you had light beams coming out of there like 3 seconds before pressing the buttons, that would be scary weird.
