Gravity density.
Whenever a sufficient mass is squeezed into a small enough volume ... then a black hole occures.
"Normally" this only ocures when a massive star runs out of (hydrogen) fuel and collapses in on itself.

Which event may signal the development of a new black hole?
The only event that we know of, that might result in a black hole, is a Type II supernova.
What can happen to photons approaching a black hole?
Light that passes near a black hole but does not cross the event horizon is bent toward it in what is called gravitational lensing. The closer the light passes to the black hole, the more it is bent. For someone with an up-close view, this lensing would result in a highly distorted image of whatever is behind the black hole. Photons that cross the event horizon are lost inside of it forever, and their energy is added to the mass of the black hole.
Is there a such thing as white holes and if there is what happens if a black hole collides with it?
It is not known whether there actually are white holes, or whether they might exist - and if they do, exactly what properties they would have. White holes are a possible solution to the equations of Relativity, but that doesn't mean they actually exist. The problem is that they are in a way the reverse of a black hole - nothing can get OUT OF a black hole, and nothing can get INTO white hole. As a result, it seems to be impossible to destroy a black hole... But similarly, it would also be impossible to create a while hole.
What is emitted when a star is swallowed by a black hole?
If say in the event of gas interacting with a black hole in a nova then fusion would occur as matter is accreted into the black hole but when any matter pierces the event horizon there is no way of escape unless it escapes as hawking radiation.
What does a black hole do with what it suck in?
The material sucked in to a black hole becomes part of the black hole - that is, a black hole crushes matter to an nearly no size, at all.
Why is there a black hole?
Black holes are the result of a large star that has collapsed.
How the black hole make?
A black hole is the result of the gravitational collapse of a massive star. This happens when the star runs out of fuel.
What is a black hole and how is it related to a star?
it is result of a dead star
Which event may signal the development of a new black hole?

How many star can form a black hole?
The death of any star greater than about 5 times the mass of our Sun is likely to result in a black hole.
What forms a black hole?
When a massive star dies, gravity forces it to fall in on itself, and the result is a gigantic explosion called a hypernova. The leftover of a hypernova is a black hole.
What kinds of stars result from death Black holes?
A dead or dying star will start to create a 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.
Is the bigbang the direct result of release of matter from a black hole?
No - nothing can escape a black hole - not even light. Black Holes are found in space - the Big Bang didn't happen in space, it created space.
Did stars older than the universe create a black hole that resulted in the big bang?
It is a possibility that the Universe resulted from a black hole, and that black holes in our own Universe result in new universes. But all this is extremely speculative.
A collapsed star from which light cannot escape?
The collapses star gets squeezed by collapses gas and turns into a 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.
