The most distant quasar is "JO313-1806". Its redshift is z = 7.64. [ Z E (femitted _ fobserved) / fobserved ] Assume that the redshift is due to relative motion. Then how fast is the quasar moving away from Earth? ( speed as the fraction of c = ) 0.974 You are correct. _ _ . . W Your receipt no. is 153-2271 @ 20km / 5 According to Hubble's Law, the distance (r) depends on the speed of recession (v) according to v 2 HOT where H0 % Miy How many years are required for light to travel from the quasar to Earth?
