Answer 1

this statement is true Edwin Hubble did discover the movement of Galaxies

Answer 2

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 :

$v=H_0\ r$

where,

$v$ is recessional velocity.

$H_0$ is Hubble constant.

$r$ is distance.

So, the given statement is True.
