Hubble's Law states that the greater the distance to a galaxy, the greater its redshift. This implies that galaxies are moving away from us at a speed proportional to their distance from us. Hubble's Law states that the greater the distance to a galaxy, the greater its redshift. This is because galaxies are moving away from us and the light they emit is stretched out (redshifted) due to the expansion of the universe.
