The Hubble constant
Explanation:
All galaxies appear to be receding from one another.
Galaxies' motion is described as motion of islands in our universe.
And the velocity of a galaxy is estimated by the Doppler Effect ( the light emitted by a source is shifted in wave length, by the motion of light source).
In respect of this motion, Edwin Powell Hubble (1889-1953) had discovered, in 1929, the linear correlation that is given in the answer.
As of now,
