In order to estimate the age of the universe as 1/H₀ , astronomers must make a number of assumptions. Which of these is NOT one of the necessary assumptions? A) The universe's expansion rate is the same in all directions. B) The Milky Way Galaxy is the center of the universal expansion. C) The value of H₀ is indeed constant. D) The speed of the expansion has been constant through time.

The assumption that the Milky Way Galaxy is the center of the universal expansion is not necessary for estimating the age of the universe as 1/H0. The cosmological principle, which is widely accepted in astronomy, states that the universe is homogeneous and isotropic on large scales, meaning it looks the same in all directions and from all points in space, thus negating the need for a central point like the Milky Way in such calculations.
