How do we know that there is much more mass in the halo of our galaxy than in the disk?
A) There are so many globular clusters in the halo that their total mass is greater than the mass of stars in the disk. B) Stars and gas clouds in the outskirts of the Milky Way orbit the galaxy at much higher speeds than we would expect if all the mass were concentrated in the disk. C) We have discovered that the halo is filled with an enormous number of brown dwarfs that have a combined mass much greater than the disk. D) Laboratory experiments have proven that the halo must be full of subatomic dark matter particles.
