Don't they measure distance and time by redshift (ie colour)
What even is color if not seconds^-1?
Yeah true, but I think they actually use wavelength of red shift, which is distance.... traveled by light in the time it takes to make a full cycle. So I guess we're back to seconds again.
I think they use this for distance and time because at scales being dealt with they have the same implications.
