Define Hubbles law

Hubble's law (E.P. Hubble; 1925): The relationship discovered between radial velocity and distance. The further away a galaxy is away from is, the quicker it is receding away from us. The constant of proportionality is the Hubble constant, H0. The cause is interpreted as the growth of space time itself.
