It's hard to compare. Probably the hypernova. According to the Wikipedia article on supernovae, a supernova can influence Earth's biosphere even at a distance of 3000 light-years. And a hypernova is supposed to be a some sort of "super-supernova". On the other hand, while most black holes are fairly harmless if they are just a few light-years away, a quasar emits typically has a brightness of over 10 million million times that of the Sun; that means that at a distance of about 50 light-years, it would look about as bright as the Sun does to us. I would guess that at a distance of 3000 light-years a quasar would be fairly harmless, unless you happen to be right in the main particle beam.

Why do black holes get more dangerous as more stuff falls into them?
Anything that falls into a black hole becomes part of that black hole's mass, which makes the gravity stronger and causes the event horizon to grow larger.
What would happen if atmospheric pressure came near a black hole?
That would depend on the mass of the black hole, and how close it came. A black hole the size of a star, a few light-years distance, would not be any more dangerous than a star at the same distance.
What makes a black hole stronger?
If a black hole is more massive (it has more mass), it will have a stronger gravitational attraction.
If 2 black holes join together what hole will it become?
A more massive black hole.
Are black holes the strongest object in space?
That depends exactly how you interpret the term "strong". In its vicinity, the black hole distorts space more than anything that is NOT a black hole; so much that nothing can get out of the black hole. But at some standard distance, a galaxy, for example, would have more gravitational attraction than a black hole, simply because it has more mass. At least, so far no black hole of the mass of an entire galaxy has been found.That depends exactly how you interpret the term "strong".

What is more dangerous than a supernova?
A Hypernova - especially if you are next to it. A black whole is dangerous, but only within the event horizon

Could a hypernova form an intermediate mass black hole?
Supernovae, including hypernovae, are expected to form stellar black holes. The stars that eventually become supernovae (or hypernovae) don't have the mass requird for an intermediate-mass black hole. It is not yet entirely clear how intermediate-mass black holes or supermassive black holes form; perhaps they start as a stellar-mass black hole and gather more mass, or perhaps a larger object, such as a gas cloud, somehow collapses directly into a gigantic black hole.
What is the difference between a Scchwarzschild and a Kerr black hole?
A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole. Since the latter is more complicated to describe, it was developed much later.A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole.

How many people know's that we're getting closer to a black hole?
This is nothing to worry about. There are other, much more immediate, dangers to mankind. The closest known black hole is at a distance of about 3000 light-years, and even if there were a black hole at a distance of the nearest star (ca. 4 light-years), it wouldn't be any more dangerous than the stars themselves.
What would happen if atmospheric pressure came near a black hole?

Wouldn't the large hadron collider create a black hole?
Some believe this already happens; in this case, the black hole would evaporate quickly.The possibility of the LHC creating a dangerous black hole or other dangerous stuff has been considered, but scientists don't take this possibility very serious, mainly because cosmic radiation produces impacts with millions of times more energy, on a daily basis - and so far, the Earth has not been destroyed.Some believe this already happens; in this case, the black hole would evaporate quickly.The possibility of the LHC creating a dangerous black hole or other dangerous stuff has been considered, but scientists don't take this possibility very serious, mainly because cosmic radiation produces impacts with millions of times more energy, on a daily basis - and so far, the Earth has not been destroyed.Some believe this already happens; in this case, the black hole would evaporate quickly.The possibility of the LHC creating a dangerous black hole or other dangerous stuff has been considered, but scientists don't take this possibility very serious, mainly because cosmic radiation produces impacts with millions of times more energy, on a daily basis - and so far, the Earth has not been destroyed.Some believe this already happens; in this case, the black hole would evaporate quickly.The possibility of the LHC creating a dangerous black hole or other dangerous stuff has been considered, but scientists don't take this possibility very serious, mainly because cosmic radiation produces impacts with millions of times more energy, on a daily basis - and so far, the Earth has not been destroyed.
What makes a black hole stronger?
If a black hole is more massive (it has more mass), it will have a stronger gravitational attraction.
Is a koala bear more dangerous than a black bear?
No. Black bears are far more dangerous.
What is more dense black hole or star?
A black hole is more dense. In principle, the black hole exists all at one point. So its volume is zero, and its density is infinite.
If 2 black holes join together what hole will it become?
A more massive black hole.
