Hubble's Law is similar to the Cosmological Constant the Albert Einstein abandoned (called his greatest mistake by Einstein himself). The Hubble Constant is a value that corresponds to the expanding Universe.

While constantly being refined, the value for Hubble's Constant is around 71 km/s/Mpc.

Hubble's Law:

We can use this law to determine distance to a galaxy:

To determine the value of v, we can use the formula for determining redshift:

then use:
