please could somebody please explain how and why the wavelengths of photons increase with the expansion of space?
thanks.
i thought i understood the whole expansion acording to the Hubble law and the scale factor thing, and the surface of last scattering, and the redshift, but this concept is messing my head up.
unless it is the redshift?
thanks V. Much
