- TL;DR Summary
- In the first edition of Schutz (1985), the author states that the Hubble flow can't make galaxies recede faster than the speed of light.
In the last chapter of Schutz devoted to Cosmology, Schutz writes
The consensus seems to have swiftly changed. When did that happen? Was it debated at all?
So it seems that in 1985 it was assumed as obvious that the recession speed could not exceed ##c##.Moreover, ## v = Hd ## cannot be exact since, for ##d\gt 1.2 ~10^{26}~\rm{m}= 4000~ \rm{Mpc}##, the velocity exceeds the velocity of light!
