The Hubble Constant is a unit used to describe expanding spacetime, which is defined as speed (kilometres per second) over a given distance (per megaparsec). As part of an equation called Hubble’s Law, it describes an accelerating expansion of distance between all points in the Universe.
In theory, the constant’s value is calculated by combining the velocity of distant galaxies as they appear to move away from us, along with an estimate of their distance.
