qânun-e Hubble (#)

Fr.: loi de Hubble   

The speed with which a galaxy recedes from us is directly proportional to its distance. Hubble's "law" is only statistically correct, as individual galaxies can have quite large random velocities around this overall → Hubble flow. It should be underlined that Hubble was not the first to discover the → velocity-distance relation. Two years before Hubble, in 1927, Georges Lemaître (1894-1966) had derived the relation and published it in a paper in French which remained neglected (→ Friedmann-Lemaitre Universe).

After Edwin Hubble (1889-1953), the American astronomer who published his results in 1929; → law.
