Question

hubble's laws statement

Answer 1

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

Recessional Velocity = Hubble's constant times distanceV = Ho D

where

V is the observed velocity of the galaxy away from us, usually in km/secH is Hubble's "constant", in km/sec/MpcD is the distance to the galaxy in Mpc

Answer 2

Hubble's law is the statement in physical cosmology that the red shift in light coming from distant galaxies is proportional to their distance. The law was first formulated by Edwin Hubble and Milton Humason in 1929 after nearly a decade of observations.

Recessional Velocity = Hubble's constant times distanceV = Ho D
