Expanding and lifting.

The Hubble – Lemaitre Law: v=H0D

V (Velocity) equals D (distance) times H-nought (the Hubble-Lemaitre constant).

 

This formula describes the relationship between the distance of galaxies and the velocity at which they are receding from us. Put simply it says the farther away a galaxy is, the faster it is receding.

 

This relationship has been widely accepted as evidence that the Universe must be expanding, with the notable exception of Edwin Hubble who was happy there was a relationship between the redshift of galaxies and their distance, but never really accepted it as evidence that the whole Universe was expanding.
