Hubble uncovered a very simple relation between the speed at which a galaxy moves away from us and the distance to the galaxy 1: the … WebThe Hubble time is defined as the age taken by the universe to expand if the expansion was linear and in a different real age. This is dependent on the dimensionless factor, which is dependent on the mass and energy of the content in the universe. Hubble time is given as follows: tH = 1/Hο = 1/67.8 (km/s)/Mpc = 4.55.1017s = 14.4 billion years. comminuted facial fracture
