Hubble's constant value higher physics
WebA parsec is a unit of cosmic distance that equals 3.26 light years. You can learn more about cosmic distances in our Basics of Astrophysics series. So, if the value of the Hubble constant is 70 Km/s/Mpc, it would mean that for every megaparsec of its distance, a galaxy will acquire an extra recessional velocity of 70km/s.
