I have recently looked into black holes but I haven't seen anything in regards to why a black hole doesn't increase in size and pull. If the gravitational field of that object is overcome and causes it to collapse as well as pull other objects into it wouldn't the mass and volume of this object increase? In turn, wouldn't the density potentially increase? If all of these were to increase wouldn't it continuously get bigger? It seems this isn't the case as the topic isn't discussed where I have looked so far. Could anyone help explain why this is the case? Thank you in advance.

because the matter being sucked into them is going through a worm hole and being transfered to somewhere else in the universe.

Even if its mass increased, it's volume wouldn't because a black hole has infinite density. I think the mass can increase, though, and when it does, the area of the event horizon (the closest light can come to the black hole without gettig pulled in) does increase.
Black holes can also get smaller by a complicated process invloving antiparticles. As far as I was able to understand, particles and antiparticles can spontaneously appear near each other and almost immediately annihilate each other. But if they're close enough to a black hole, sometimes one of them will be pulled in. If it's the antiparticle, it will annihilate with some of the matter already in the black hole, making it smaller.
At least, that was the understanding some 15-20 years ago. I have read Stephen Hawking's "A Brief History of Time" several times, but haven't had access to anything more recent.

interesting question, as it turns out mathematically, as soon as a black hole forms its size (the stuff at the centre) is 0.The force of gravity is now stronger than the others forces holding it apart. Adding more matter to it doesn't change its size at the centre mathematically. keep in mind that the singularity (stuff at centre) is really unknown and current physical laws don't work in that region. It could be that matter and gravity are the same thing just like matter and energy are and in a black hole all the matter is turned into gravity and in that case the black hole does get bigger because the gravity of the black hole increases with more mass.
it depends on how you look at it.

Ultramassive black holes are the biggest in life. they have greater advantageous than 10 billion solar plenty. Supermassive black holes have between a million million and 9 billion image voltaic plenty. There additionally are Intermediate-Mass black holes that have a hundred to a million million solar plenty. The black hollow in M87 is desperate 3 billion image voltaic plenty and 18 billion km in diameter. it quite is approximately 3.5 billion mushy years away. The OJ287 black hollow is approximately 18 billion solar plenty and has a a hundred million image voltaic mass black hollow orbiting it. The smaller black hollow will probable be swallowed up in approximately 10,000 years. for the rationalization that that OJ287 is regarding the scale of an person-friendly galaxy, think of how briskly the smaller one is going because of the fact it orbits OJ287 each 12 years & Pluto takes 248 years to pass around the solar as quickly as. additionally that's approximately 3.5 billion mushy years away. Sorry if we compelled you, Oklatonola. The "length" of a singularity heavily isn't the gadgets quantity, it quite is the occasion horizon or the place no longer something escapes from. because of the fact the mass will enhance, gravity's attain extends. this is the scale astronomers communicate approximately, now no longer the actual merchandise which would be unable to be measured.

If they consume enough matter, they do grow. Stephan Hawking also showed they slowly evaporate.

They're perfectly sufficient to sustain themselves the size they are. If they got bigger or smaller they'd become unstable. *quack*

They do..
There are black holes of all sizes...

my impression is that it does get bigger. But I'm not steven hawking...
