Can you grasp that? No, never heard of Doppler. A pitcher for the Mets? 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.
