There is no such thing as a black hole with the mass of a galaxy. At least, none that we know of, and not if you are thinking of a large galaxy like the Milky Way. The largest known black hole has about 20 billion solar masses - which is still much less than the mass of a typical galaxy. For example, our Milky Way is estimated to have a mass of about 700 billion solar masses. However, such as massive black hole does have a mass comparable to smaller galaxies, i.e., dwarf galaxies. In any case, such huge black holes are found in the center of large galaxies.
What else can I help you with?
Where are black holes generally found in a galaxy?
Most or all galaxies appear to have supermassive black holes at their centers and probably have stellar mass black holes scattered throughout.
Are there black holes in our galaxy?
Yes. Our galaxy has a supermassive black hole at its center and likely millions of stellar mass black holes scattered throughout.
Can there be more than a black hole in a galaxy?
Yes. Most, of a galaxy's mass is stars and nebulae, not black holes.
Are there any black holes in your galaxy?
Yes. There is a supermassive black hole at the center of the galaxy and a number of stellar mass black holes through the rest of it.
Does a galaxy contain black holes?
Not really "a" black hole - many black holes. It is currently believed that all, or most, galaxies have a huge black hole at its center. Any galaxy should also have lots of smaller black holes - so-called "stellar" black holes, because they have approximately the mass of a star (larger stars can become black holes).
Supermassive black holes found at the centers of galaxies are related to the properties of those galaxies in the following way?
Supermassive black holes found at the centers of galaxies are related to the stellar velocity dispersion in the bulge of the galaxy. To a lesser degree, there is also a correlation with the mass of the galaxy.
WHAT OBJECT WITH THE GREATEST MASS?
The object with the greatest mass is probably a supermassive black hole located in the center of a galaxy, such as the one in the Milky Way galaxy. These black holes are believed to have masses equivalent to millions or even billions of times the mass of our sun.
What is the common size of a black hole?
There is no "average" mass for black holes throughout the entire universe. Black holes range greatly in mass, depending on how they were formed, and how long they have existed if you take Hawking Radiation into account. Mass can be anywhere between a couple hundred protons, such as those created by cosmic rays striking Earth's atmosphere, or an enormous mass such as those in the center of almost every spiral galaxy.
Is this galaxy near a black hole?
Our galaxy contains a supermassive black hole at the center and probably several million stellar mass black holes scattered throughout.
Is a black hole bigger than galaxy?
No. At least, the black holes in existence so far are much smaller in size, and have much less mass, than a galaxy. However, note that the black hole in the center of the largest galaxies can have more mass (but not more diameter) than some dwarf galaxies.
Where is the black hole located in the galaxy?
Black holes can technically be any where. Some scientists believe that there is a black hole in the center of our galaxy along with many other galaxies. Because black holes are so difficult to detect, they can be very dangerous.
How does a black holes acquire greatest mass?
Most black holes are stellar mass black holes with masses comparable to those of large stars as they form from the collapse of massive stars. Scientists know of the existence of supermassive black holes that are millions to billions of times the mass of our sun and can be found in the centers of most galaxies. Scientists still do not know how these black holes become so massive.
