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.
What else can I help you with?
How are supermassive black holes different from stellar mass black holes?
In their mass. a "stellar black hole" has a few solar masses (a few times the mass of our Sun), while a supermassive black hole (found in the center of most galaxies) typically has a mass of millions or billions times the mass of our Sun.
Do medium size stars become black holes?
No. They do not have enough mass to become black holes. Depending on the mass they will either become white dwarfs or neutron stars.
How strong is the black holes gravitational pull?
The strength of a black hole's gravity depends on the black hole's mass and how far your reference point is from the center of mass.
How are black holes classified?
They can be classified according to whether they rotate or not; their electrical charge; but especially their mass.
Is black hole the size of an atom?
The most relevant quantity is the black hole's mass. Note that the black hole's diameter (the diameter of the event horizon, really) is directly proportional to its mass. The largest galactic black holes known seem to be around 20 billion solar masses. Check the Wikipedia "List of most massive black holes" for more details. Note that the mass of some of these black holes is not very well-known.
How are black holes dissipated?
They will gradually evaporate, due to Hawking radiation. At the current stage of the Universe, black holes of the mass of a star will acquire mass much, much faster than they evaporate - even if they only absorb the background radiation. In the far, far future, such black holes can slowly evaporate.
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 has a lot of mass?
Black holes.
What is the most common form of black holes in the universe?
Probably stellar mass black holes
How do black holes survive?
it's mass
Are black holes infinite in size and mass?
No, black holes are not infinite in size and mass. They have a finite size and mass, but their density is extremely high, leading to their strong gravitational pull.
Are there black holes the size of stars?
The relevant magnitude is mainly the black holes' mass. Since black holes are the result of collapsing stars, yes, there are black holes with the mass of a star.The diameter is usually taken as the diameter of the event horizon. This diameter is directly proportional to the mass; a supermassive black hole such as Sag A* has a diameter comparable to that of a large star.
What do very large mass star become at the end of their life cycle?
The most massive stars will die as black holes.
Is a black hole just a hole in space that contains no matter?
No. Without matter there would be no black hole. The black holes confirmed to exist so far actually have a fairly large amount of matter (or mass) - at least 2-3 times the mass of our Sun. The largest black holes have millions or even billions of times the mass of our Sun.No. Without matter there would be no black hole.

Do black holes provide the physical force to structure galaxies?
No. The mass, and therefore the gravitation, of black holes, are only a tiny fraction of matter in the galaxies. The greatest part of the matter in a galaxy is dark matter - matter of unknown composition at the time of this writing.
Is an Intermediate-mass black hole a type of black hole?
Yes. Intermediate-mass blackhole is a medium size black hole. Scientists have found stellar black holes and supermassive black holes but there is no prove that Intermediate-mass black type of black holes exist. My opinion is that they do exist because when a black hole is becoming a black hole supermassiveblack hole it will need to go though this stage of intermediate-mass black hole.
What kind of stars become black holes low mass or medium mass or high mass?
High-mass stars might become black holes, if the remaining matter (after the supernova explosion) is sufficiently large.
