According to the Hubble law the more distant galaxies, the greater apparent recessional velocity. The Hubble law states that as the distance to galaxies increases, the apparent recessional velocity increases. The main equation is: <span>Recessional Velocity = </span>Hubble's constant<span> times distance</span><span>.</span>
