It certainly does, and that is exactly what is happening. You have not demonstrated even a single fact to indicate the contrary. < > It's no use complaining that "it can't be", because "it is", whether we like it or not. |
But this doesn't answer the question of
how the photon is supposed to have its wavelength stretched. It might make sense for the expansion of spacetime to stretch out light waves if spacetime were the medium for light. Is anyone making that argument?
