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".
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?
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.
Did astronomers believe that the sun was part of earth?
No.
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 do astronomers use white dwarfs to date the universe?
They don't.

What is the difference between white dwarfs and black dwarfs?
their colour is one thing but a black dwarf originates from a white dwarf
In what part is a black hole in the universe?
Astronomers believe that black holes exist in the center of every universe. They even think that there may be a black hole in the center of our galaxy, the Milky Way
What are the stars that emit no light?
Black dwarfs of black holes.
What kind of Astronomers study black holes?
specifically, "astronomers" that study black holes are called cosmologists.
Why do astronomers believe that a supermassive black hole lies at the center of the Milky Way galaxy?
Astronomers believe a supermassive black hole lies at the center of the Milky Way galaxy because of the high speeds of stars and gas near the center, as well as the intense radiation emitted from that region. These observations suggest the presence of a massive object that can only be explained by a supermassive black hole.
What basic shape does black dwarfs have?
A sphere.
Is there such thing as black holes?
Astronomers believe that there are black holes, but I will add that they have only been observed indirectly at great distances, so it may be that the interpretation of our observations will change in the future.
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.
