Hubble's Law is a fundamental principle in astronomy that describes the relationship between the distance to a galaxy and its recessional velocity. It's expressed by the equation v = H0 * d, where v is the recessional velocity of a galaxy, d is its distance from us, and H0 is Hubble's constant.
The Hubble's constant, denoted by H0, represents the rate at which the universe is expanding. The current accepted value as of my last update is approximately 70 km/s/Mpc. This means that for every megaparsec (Mpc) of
