Question

WHAT IS HUBBLE'S LAW??

Answer 1

The dominant motion in the universe is the smooth expansion known as Hubble's Law.

Recessional Velocity = Hubble's constant times distance

V = Ho D

where

V is the observed velocity of the galaxy away from us, usually in km/sec

H is Hubble's "constant", in km/sec/Mpc

D is the distance to the galaxy in Mpc.



thanks for asking

Answer 2

well hubble's law is that the dominant motion in the universe  dominant [means having power] is the smooth expansion known as Hubble's Law. recessional velocity = hubble's constant times distance. V is observed velocity of the galaxy away from us, H is the constant in km/sec/mph. 

hope this and the pics helps u
