An empirical law of observational cosmology stating that the velocities at which galaxies in the universe recede from one another is directly proportional to the distances between them.
The law, formulated by Edwin Hubble, that the velocities of distant galaxies moving away from the earth are directly proportional to their distance from the earth.
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.
(singular only) Alternative spelling of Hubble law.
Origin of hubble-s-law
After Edwin Powell Hubble who first formulated it
