Depending on the size of the black hole, they may or may not have:* An enormous mass;
* An enormous gravitational pull (depending how close you are, of course);
* An enormous density (depending how you define density; if you take the volume of the event horizon, a supermassive black hole actually has less density than water).
What else can I help you with?
What do black holes have an enormous pull of?
everything they can pull in everything even other stars and light itself
What do scientist think these quasar are?
Scientists think quasars are supermassive black holes in the process of consuming enormous amounts of matter.
Why do stellar masses result in black holes?
The only known mechanism to produce a black hole is the gravitational collapse of an object that has at least 2-3 times the mass of our Sun. However, it is considered possible that the enormous densities right after the Big Bang may have resulted in some black holes; for more information, read about "primordial black holes".
Is a black hole a living organism?
No. Black holes are huge stars that have collapsed so far that their force of gravity is so enormous that even light cannot escaple. (Hence, they are 'dark' )
How small can black holes get?
A star that stops producing radiation, with a mass about 2-3 times the mass of our Sun (mass remaining after a possible supernova explosion), or more, can become a black hole. There is also some speculation about miniature black holes ("primordial black holes"), with much less mass than that, which might have formed during the Big Bang, because of the enormous density that existed at that time. However, so far there is no evidence that such black holes actually exist.
Why can't people see black holes?
Black holes don't emit any radiation (except for an insignificant amount of Hawking radiation). However, if matter falls onto a black hole, it will emit x-rays before it reaches the event horizon (the point of no return), as a result of an enormous acceleration.
Why do black holes come in different sizes?
Because of their previous history. The star that converted to a black hole may have had more or less mass for a start. Also, a black hole can increase in mass when matter falls into it, so depending on the amount of matter available for the black hole, the results may vary.However, it is not yet known how the galactic black holes achieved the enormous mass they have.Because of their previous history.

What will happen to the universe 10 duotrigintillion years from now?
Only black holes and subatomic particles remain. The universe has expanded so much that these individual particles may be separated from each other by truly enormous distances. Black holes themselves are now evaporating by Hawking radiation.
What were black holes before they turned into black holes?
stellar black holes were stars (these are large)primordial black holes were pieces of the big bang (these are microscopic)
What is enormous in a black hole?
The gravity is enormous! The gravity in a black hole is high enough to stop light escaping.
Is the universe made of black holes?
No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.
Can black holes dies?
Black holes do not die but they can evaporate.
