If I "create" a stream of photons in the lab or if I spectographically select a stream of photons from a star, I get the same experimental result in a double slit experiment? In other words there is no difference between photons whose point of origin can be deduced to be eons ago vs those originating in the lab for this type of experiment; is there any quantum experiment where there would be a difference? My knowledge of quantum mechanics is not great, but, I don't think history prior to the measurement plays a role. What happens to the photon after the measurement also is not of consequence. The only thing that matters is the measurement itself. Is that right?
