Singularitys? Black holes? please explain?

Question

I read about this last night and get the jist of but can some please explain the formation in there own word so im totally clear

Answer 1

Answer 2

A black hole is made when a giant star(about 10 times bigger than our own Sun) dies! As the fusion reactions stop, it starts collapsing under it's own weight, and as it collapses it gets denser and denser and the space-time fabric abound it gets distorted to the breaking point! This "rupture" in space-time is known as a singularity, the center of a black hole! The denser an object is (the more mass is forced in the same region in space) the more gravity it has and gravity is just warped space-time!

Answer 3

Black Holes are the locations in space where there is intense gravitational field. The effect of such gravitational field is that not even light can escape.

No one knows what Black Hole contains inside it. But it is being thought that Black Holes lead to singularities. i.e. the conditions that existed before the Big Bang.

Singularity means point where things become undefined. Just as the function y = 1/x has a point of singularity at x = 0 and the function y = 1/(1-x) has a point of singularity at x = 1.

Similarly in Physics, singularity means the downfall of General Theory of Relativity. GR explains the evolution of universe with time but fails to explain the existence of point where everything was supposed to be concentrated and where everything started.

This point is undefined till date and therefore is called singularity.

Black Holes due to their strong gravitational field pulls objects in itself. Objects accelerate due to this gravitational field. At the moment the object acquires the speed of light in it, it becomes impossible to determine its behaviour and we say it has reached "Singularity".

hope this helps...

To know how Black Holes are formed, you should read articles on life and death of a star.
