The ratio of the velocity to the distance of objects in the
universe is called Hubble’s constant, the rate of the
expansion of the universe. The observation that more distant
galaxies are receding more rapidly is called Hubble’s law.
Georges Lemaître published these assertions in 1927 in
Belgium and his paper did not get attention elsewhere.
Lemaître also proposed the theory of the big bang, that all
current vectors can be traced back to a single point and time, to
the state of singularity.
