WebJust as in the Doppler Effect, where we measure the size of the Doppler 'red'-shift in terms of the speed of the object emitting the sound waves, for distant galaxies we measure their redshifts in terms of the cosmological factor, z. Close-by galaxies have z-values much less than 1.0, but very distant galaxies can have z=6 or higher.
