Actually there's this thing called a black dwarf. Its when a star gets really old, it can turn into a white dwarf. If this happens then 100 zillion years later, the white dwarf star eventually uses up all its energy and turns into a cold dark mass. It takes so long to for this to happen that scientists believe there to be no black dwarfs in the universe.
