Explanation :
Edwin Hubble used a telescope to discover the movement of galaxies in 1929. He was an American Astronomer.
The telescope invented by him is called a Hubble telescope. It has a 2.4-meter mirror.
He gives the relation between the distance to a galaxy and its recessional velocity. This is known as the Hubble law. The relation is as follows :
[tex]v=H_0\ r[/tex]
where,
[tex]v[/tex] is recessional velocity.
[tex]H_0[/tex] is Hubble constant.
[tex]r[/tex] is distance.
So, the given statement is True.
this statement is true Edwin Hubble did discover the movement of Galaxies
