"Black Holes" Myth or Mystery ?

If you ever studied in school or a science student then you surely heard this term Black Hole.
Black holes are the most gigantic and mysterious objects of Universe.Because of their immense large size they have strongest gravitational pull, and even light can't escape from it.seems to be mind boggling right? yes it is. even it is nothing about it when you start exploring black holes you might get surprised by its functioning and effects that it made on all other objects of cosmos.

You always listened by your teachers or elders in school that every object on this planet,solar system and universe follows rules of physics and works according to it. But my friend this doesn't implies on the Black holes.They shows limits to that rules and laws which are ideal for all other objects.They always makes us to rethink about our knowledge and skills that it is not enough and needs to be better more better..!

For a long time black holes considered to be as a myth! why? because their were not be any practical evidence to proof of its reality, it only lie in theories until its first ever discovery in 1971.Actually black holes are not objects they are the regions in space-time graph with tremendous gravity.Now you may be thinking of what is this "Space-time graph"? don't worry we will discuss it soon..
Their are many mysteries related to black holes nowadays, scientists always trying to figure out them but since from starting very few had been solved and most of are still fascinating us such as-
1.Why black holes are so big and heavy?
2.What is actually happened after swallowed up by black hole?
3.Where all things gone after a dive into black hole?
These are some questions which are still unanswered and keep pushing our thinking for these abnormal objects.

There is also one very famous question about black hole is "What happened with all the information associated with the matter that falls in black hole", is it losted for forever? but if we apply laws of conservation's here then it states information can't be destroyed and their is also not any way to get out of black hole even for light, this scenario gives a birth to a controversy which makes our understanding about these objects completely useless..!!
