GAMOW1 has attempted to explain the lack of correlation between apparent brightness and red-shift of quasi-stellar objects2,3 as being caused by the fact that the red-shifts are measured from absorption spectra which he has argued are caused by galaxies intercepting the light from more distant quasti-stellar objects. In this case, no correlations could reasonably be expected because the apparent magnitude would refer to one object and the red-shift to another.
