text: Because the time needed for a white dwarf to reach this stage is calculated more than the present age of the universe (13.8 billion years), now there is no hope of any dark dwarf in the universe, and the best white dwarves The temperature of the universe is an observation boundary over the age of.
text: 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 now, and the temperature of the coolest white dwarfs is one observational limit on the age of the universe.
