    LP 5. (20 pts) It is known that most of the mass of galaxies is some exotic material that doesn't interact with light or normal matter. Let's assume that this "dark matter" is due to a new elementary particle---alaskonium. Like Alaska in the winter, alaskonium in the galaxy is cold and dark. We will assume that alaskonium is a fermion and that it is so cold that it is degenerate; a gravitationally bound, nonrelativistic, degenerate gas. Take the total mass...
