Oh that's for me!!
Ok first a quick introduction.
Black holes are certain regions in universe with a great gravitational attraction.
Now how are they formed, when a giant star compresses to a single point or singularity all their gravitational energy gets concentrated at that point giving rise to black holes, as easy as that.
Now black holes are bizarre, their gravitational energy is so great that even light can't escape it, this brings us to a conclusion that we can't see them.
So there might be a black hole right next to you and you can't see it ( Just kidding ). To enable us to see something it should reflect some light but black holes sucks everything. So how our scientists saw it, through different electromagnetic spectrums.
Now another bizarre thing about them is that at the centre of all the huge galaxies there is a black hole, our milky way too has a black hole. Black holes on rare occasions suck or eat stars and when this happens the universe witnesses some of the biggest energy bursts - the gamma ray bursts.
Now the last trivia. Don't you ever wonder where all the matter sucked by black holes go, they are ejected by theoretical white holes. Now white holes are black holes in reverse, but practically they can't exist, as they would be very unstable. But back in 2006 our scientists saw a bright explosion of light, which was too bright for a super-nova they doubted it to be a white-hole, it lasted only for few seconds before disappearing.
The Big Bang that is expected to create this universe is suspected to be a white hole.
Who may know?
Hope it helps ^_^

black hole
------------------------------
Black hole is a region of very high gravitational field in which nothing can escape from it, sometimes even stars get consumed by these black holes by this we can understand that how strong is gravitational force in an black hole.
They are the darkest region in the universe, after it is formed, it can continue to grow by absorbing mass from its surroundings which can lead to the production and existence of large black holes in the universe, they just consume everything which is present around it.
There are many theories related to black holes and some of them failed to explain the formation, etc and some of them were proved wrong by the new theories but we cannot trust them as there is no such proof for those theories
astronomical pioneer John Michell proposed that even light cannot escape from the black hole, then in 1915, Albert Einstein developed his theory of general relativity and this theory was formulated and changed many times by many of the scientists.
Black hole cannot be studied easily, it has been said that their primary formation occurs because of the gravitational collapse but there may be various other reason for the formation of the black holes.
The theory of the black holes is too vast such that it cannot be explained so easily, we need to have a lot of scientific knowledge about it.
