Because the time required for a white dwarf to reach this state is calculated to be longer than the current age of the universe (13.8 billion years), no black dwarfs are expected to exist in the universe yet, and the temperature of the coolest white dwarfs is one observational limit on the age of the universe.If black dwarfs were to exist, they would be extremely difficult to detect, because, by definition, they would emit very little radiation.
