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.
