The pit of Doom

It was indeed a nice afternoon in MosaicLand,

my walk has taken me far away from the sound of the flowing stream.

Much to my amusement, my walk seems to bring me to the heart of a jungle.

Here, I saw rabbits of various shapes and sizes,

each glowing with a distinctive glow...

One by one, I saw them jump into a deep and dark pit...

Each one who jumped down was never to be seen again...

The black hole, a dark invisible star killer is an object with such a great gravity that nothing can move fast enough to escape from it, not even light.

My brother's impression of a black hole

Since light could not escape from it, we will not be able to see it even if we have the most sophisticated telescope.

Scientists and astronomers are able to predict the positions of black holes based on the behavior of stars nearby.

The birth of black hole

Scientist believes that black holes are formed when super-massive star dies.
A super massive star is a star with a great mass, such as red-giants.
Usually, a super massive star will shed out its outermost layer first when they die. This is followed layer by layer until the star is shrunk into nothingness...
However, if the gravitational pull of the star is huge enough, it will start to pull all its outer layer into its core, forming a dense, heavy object.
This object is then, known as the black hole, an object with a gravitational field so large, the space-time fabric is bended by it, preventing even light from coming out.

Spotting a black hole

How to spot a black hole?
Easy!
As I have mentioned earlier, scientists observes stars nearby to find black holes, but how exactly?

Imagine water going down the hole...
It swirls around first, before actually going in...

  In the same manner, dust particles and cosmic gases forms a disk around a black hole. This disk, known as accretion disk, is what astronomers look for when they are on a black hole hunt.

Ah,..
what an amusing thing to do,
Watching rabbits attracted helplessly into the pit of doom,
falling, falling and falling,
Into the never-ending pit of doom...
