"If the apparent magnitudes of the nebulae are corrected merely for the effect of the red-shift in diminishing the energy of their observed light, we have seen that Hubble claims that the system is uniformly spread out in space. If, however, the nebulae are receding, an additional dimming factor arises, and the corresponding correction for distance when incorporated in the calculation destroys the homogeneity. Instead, the number of nebulae per unit volume of space now appears to increase as we recede towards the confines of the visible universe. Rightly or wrongly, Hubble maintains that such a picture would imply that we were in a privileged position in the universe, being in the region lease densely populated with nebulae. On these, and other grounds, he is inclined, therefore, to reject the Doppler-interpretation of the red-shifts and to regard the nebulae as stationary."
