The Answer of Redshift z = v_r/c, where v_r is the apparent recessional velocity, and c is the speed of light.Is it possible to observe a redshift greater than 1.0, or lower than=1.0? A) Neither is possible. B) Yes, it is possible to measure both. C) It is possible to measure z $\lt$ -1.0, but not z $\gt$ 1.0. D) It is possible to measure z $\gt$1.0, but not z $\lt$ -1.0. E) Redshifts greater than 1.0 and less than -1.0 are the only possible redshifts.

Redshift Z = Vr/c, Where Vr Is the Apparent Recessional <\lt<

Redshift Z = V_r/c, Where V_r Is the Apparent Recessional $\lt$
