... velocity = 6x the speed of light!!! Why? Because the redshift is cosmological – due to expansion of space – NOT due to the Doppler Effect, so z is not equal to v/c In fact, 1/1+z is the size of the universe compared to now; z = 6 means that we see the object at a time when the universe was 1/7 of it ...
