Explanation:
Hubble's law states that the distance to the galaxy is directly proportional to its velocity by which it is moving away from us( recession velocity). It can be stated as v= Hο×D
Where H_o= Hubble constant ( It gives the age of universe)
The equation revolutionized the field of cosmology as it showed galaxies beyond our local group. It helped in calculating the age of universe. And the fact that the galaxies are moving away from us meaning the universe is expanding.
