Can you grasp that? Then consider a distant galaxy A and a galaxy B that is between us and A. Due to expansion of the universe we are receding rapidly from A and less rapidly from B. When a photon A emitted is received at B it's wavelength will have increased due to the Doppler shift as B recedes from A. Suppose B immediately transmits a photon of that wavelength toward Earth. It will suffer a Doppler shift of increased wavelength as received at Earth. Now just skip B. The expansion of space causes a continuous Doppler shift as a photon traverses space. Brent The problem with Doppler for photons can be summarized in a simple question most physicists can't answer, or even pose; where is the wave which the moving source allegedly interacts with to produce redshift? A photon, as JC admits, is a point particle. I claim it manifests no wave properties other than as a ensemble. The polarizer experiment given by JC just shows that photons have no polarization before measurement.
