What else can I help you with?
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.
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.
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.
Are there more white dwarfs of more black holes?
I think white dwarfs. This is because they are much more low mass than black holes. White dwarfs are much more common in the universe than black holes, because we have only discovered a few black holes whereas we are aware of many white 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".
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.
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.
Do astronomers believe in black dwarfs?
Black Dwarfs are still theoretical bodies in the Universe. Belief and scientific observations are two different things. In theory, they will exist, but until one is observed, there existence can not be confirmed. See related question
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.
How long will a black dwarf star live?
It is unknown. Scientists belive that, since the life length of white dwarfs are so long, there aren't any black dwarfs in our universe yet.
What is more common in our galaxy white dwarfs or stellar mass black holes?
There are more white dwarfs. Only the most massive stars can form black holes. White dwarfs form from low to medium mass stars, which far outnumber the supermassive ones.
