... 7. Why do we believe that most of the mass of the Milky Way is in the form of dark matter? A. Theoretical models of galaxy formation suggest that a galaxy cannot form unless it has at least 10 times as much matter as we see in the Milky Way disk, suggesting that the halo is full of dark matter. B. T ...
