Hubble's law

Hubble's law  (hblz)

A law of cosmology stating that the rate at which astronomical objects in the universe move apart from each other is proportional to their distance from each other. Current estimates of the value of this proportion, known as Hubble's constant, put its value at approximately 71 kilometers per second per megaparsec.
