- speed calculation between two groups at different redshifts : redshift 10 & redshift 6.
If many quasars are at redshift 10, and another group is at redshift 6, what is the speed of the second group relative to the first? The redshift 10 group can be considered "at rest", so the redshift 6 group is heading in our direction at what rate? For this scenario, let us assume all the quasars are at same distance (as suggested by zero time dilation difference). Answer in percent of lightspeed please, but kilometers per second is ok, I can handle that conversion.
