Definition of Hubble's law in English:

Hubble's law


  • A law stating that the redshifts in the spectra of distant galaxies (and hence their speeds of recession) are proportional to their distance.

    • ‘One is the red shift of light coming from remote galaxies which is usually attributed to Doppler's effect and obeys Hubble's law.’
    • ‘Next he talked a bit about Hubble's law; that the velocity at which a galaxy is moving is proportional to its distance away from us.’
    • ‘Doesn't that contradict Hubble's law, which states that distance is correlated with age?’
