Examples of things which are not black holes would make a large list indeed.. but would include Abe Vigoda's spleen, the Symphony #3 in C Opus 78 by Camille Saint-Saens; and a box of dead marmots.

Is a black hole an example of negative pressure?
No. The only force at work with a black hole is gravity.
A black hole is the ultimate example of what law?
The law of gravity.
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".

How do scientists try to locate black holes?
A black hole can be located due to its gravitational attraction. If matter falls into the black hole, it will emit x-rays; also, even if this is not the case, the black hole can be detected by the gravitation it exerts on nearby objects - for example, if an object orbits the black hole. A black hole may also change the direction of light emitted from behind it, for example, from a far-away star or galaxy. This is known as "gravitational lensing".
Does a black hole have billions of stars in it?
No. A black hole intakes matter. After it is broken down by gravity. Then it releases it as particles (Neutrinos for example) There is not another universe within a black hole. Nor do stars or matter stay within the black hole. Of course all of this is theory with some really fun math attached to it.
Why can't objects come out from the black hole?
Within the so-called event horizon, space and time around the black hole are distored in such a way that the only way a ray of light (for example) can move is closer towards the black hole's center.
A collapsed star from which light cannot escape?
The collapses star gets squeezed by collapses gas and turns into a black hole.
What happens when something gets too close to a black hole?
It will fall into the black hole. The same happens if something gets too close the Sun, for example - it will fall into the Sun.
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.

What is a burst of light from a black hole?
Bursts of light from black holes are the result of the accretion (or "consumption") of matter by black holes. Quasars are an example of this.
What does the black hole do to the star?
A black hole originated as a star, that is, the star converted to a black hole.
Why do black holes not suck things up?
A black hole will "such things up" if such things get sufficiently close to the black hole. This is a result of its gravity. Similarly, our Sun will "suck things up" if they get too close - for example, a comet might crash onto the Sun; the comet's mass will increase the mass of the Sun. Please note that if, for example, our Sun becomes a black hole (it probably won't, since it doesn't have enough mass for that), without changing its mass in the process, the Earth will continue orbiting the black hole as it orbited the Sun before. It will NOT be "sucked up" in the process - the black hole's gravitational attraction would be the same as the Sun's attraction before becoming a black hole.
