Do astronomers believe in black dwarfs?
Astronomers theorize that black dwarfs will eventually form as very old white dwarfs cool down and cease emitting light. However, black dwarfs have not been observed yet as the process of their formation is estimated to take longer than the current age of the universe.
Are black dwarfs a solid liquid or a gas?
None of the above. White dwarfs and the black dwarfs they will become consist of a unique state of matter called electron degenerate matter.
Are there more white dwarfs of more black holes?
There are more white dwarfs than black holes in the universe. White dwarfs are the end stage of low to medium mass stars, while black holes are formed from the remnants of massive stars. Since low to medium mass stars are more common than massive stars, there are more white dwarfs in the universe.
Why have no white dwarfs cooled to form black dwarfs in the galaxy?
Black dwarfs have not formed in the galaxy because the universe is not old enough for any white dwarfs to have cooled sufficiently to become black dwarfs. The process takes trillions of years, and the universe is estimated to be only about 13.8 billion years old.
What are some examples of back dwarfs?
There are currently no black dwarfs. The time it would take for a white dwarf to cool to a black dwarf is greater than the current age of the universe.

What is the difference between white dwarfs and black dwarfs?
their colour is one thing but a black dwarf originates from a white dwarf
What are the stars that emit no light?
Black dwarfs of black holes.
What basic shape does black dwarfs have?
A sphere.
How Many Black Dwarfs are thought to exist?
No black dwarfs are thought to exist. The estimated time it takes for a white dwarf to cool to a black dwarf is greater than the current age of the universe.

There are more white dwarfs than black holes in the universe. White dwarfs are the end stage of low to medium mass stars, while black holes are formed from the remnants of massive stars. Since low to medium mass stars are more common than massive stars, there are more white dwarfs in the universe.

Why have black dwarfs not been seen?
It is estimated that it would take trillions of years for a white dwarf to cool to a black dwarf, which is more than the current age of universe. So black dwarfs do not exist yet.
What is the entrance to the Black Sea?
The Bosporus Strait in Istanbul is usually considered the entrance to the Black Sea.
Are black dwarfs hot?
Black dwarfs by their name are the opposite of hot. A black dwarf becomes a black dwarf when all residual heat has escaped into space. They will be as cold as space itself. See related question. If this is not an astronomy question but one of "another sexual" nature then I suggest re posting with more precise details in the question.
