WebThe universe is expanding 73.5 ±1.4 km/sec/Mpc. The difference between the two speeds explains the difference between two types of redshift: Doppler redshift and Cosmological redshift. These two different velocities result in two different redshifts. The second one gives the Doppler redshift because it’s an actual velocity.
