3. [10 pts] The cosmological principle states that the universe is homogeneous and isotropic. The mean density of the universe is Pavg = 3 1027 kg m. Consider a density within a sphere with a diameter of i) 3 m that encloses a person that weighs 100 kg; ii) 3 AU that encloses the Sun and the Earth; and iii) 3 Mpc that encloses the Local Group (the dominant contribution comes from MW and Andromeda galaxy). For simplicity, assume that the total mass of Andromeda is identical to that of MW. Is the universe homogeneous at these scales?
