right, right, i've made a rather large assumption there...
relativity teaches us that light leaving a large gravitational force will be red shifted and similarly, light entering a large gravitational force will be blue shifted thus we can think of gravity as pulling at light just as it pulls at matter, not effecting it's speed but it's wavelength.
the large assumption i have made is that much older galaxies will be that much more dense - in fact generally proportional to their distance/age.
