White dwarfs can be quite old, often exceeding several billion years. They represent the final evolutionary stage of stars like our Sun after they have exhausted their nuclear fuel and shed their outer layers. The oldest white dwarfs are estimated to be around 11 to 14 billion years old, making them some of the oldest objects in the universe. Their cooling rates can be used to estimate their ages, as they gradually lose heat over time.

Why have no white dwarfs cooled to form black dwarfs in our galaxy?
No white dwarfs have cooled to become black dwarfs in our galaxy because the universe is not old enough for this process to occur. White dwarfs take longer than the current age of the universe (approximately 13.8 billion years) to cool sufficiently to become black dwarfs, likely requiring hundreds of billions to trillions of years. As a result, all white dwarfs in the Milky Way are still in the cooling phase and none have yet reached the stage of becoming black dwarfs.

Why have no white dwarfs cooled to form black dwarfs in the galaxy?
According to astronomers and authors Jonathan Weiner and Carl Sagan, white dwarfs - which have been an accepted entities by all astronomers for decades - require an amount of time to "cool down" that well exceeds the current age of the universe - hence there hasn't been enough time for any of them to cool down yet and become "black dwarfs".
Why do all white dwarfs have about the same mass?
All white dwarfs do not have about the same mass. White dwarfs vary in mass because the stars they form from are not all the same mass.
