BLACK HOLE


BLACK HOLE

Black hole is one of the most enigmatic and mysterious objects in the universe. It cannot be seen even with most powerful of telescopes. No object can escape once it falls into a black hole. Even light is held in its grip. Space is highly curved and time moves extremely slowly close to a black hole. Apparently, a black hole is a region of greatly distorted space [and also time].


A black hole, once create, is like a bottom precipice that cannot be filled in or ‘plugged’ with anything. They are almost perpetual holes in space time. They grow at the expense of matter falling into them. Even when no matter fall into black hole, it may stay in the same state for trillions of years.

What are black holes?

Have you ever had to vacuum your bed room? When you do so, watch closely because you will see dirt, and crumbs start to move towards the vacuum cleaner, cleaning up derbies left behind in outer space.
 It is not suction power that makes thing fall into a black hole. Suction power that makes things fall into a black hole. Suction would not be strong enough. Instead a black hole uses the power of gravity to pull things towards it.

How do black holes form?

When a large star runs out of fuel it can no longer support its heavy weight. The pressure from the star’s massive layers of hydrogen press down forcing the star to get smaller and smaller. Eventually the star will get even smaller than a atom. Imagine that for a moment an entire star squashed up into less space than a tiny atom.

How can something get smaller, but retain the same amount of mass, or stuff?

It is really quite simple. If you take a sponge the size of a soda can you can easily squish it in your hands until it is completely covered. But here is the interesting part. If you make something smaller by squishing it, its gravity becomes much stronger. Imagine then, if you squish a star into the size of a atom how powerful its gravity would become.
A black hole’s gravity becomes so powerful that anything including light that gets too close, gets pulled in. that’s right, not even light can escape the grasp of a black hole. The middle of a black hole is called a singularity. Singularity is a simple a big word that means squashed up star.

When you get to close to the singularity you will begin to fall into it. When you begin to fall toward it you know you have passed the outer event horizon. At this point you could still escape by  you had hurry, because as soon you pass the inner event horizon it will be too late.

How can you fall into a black hole?

Think of the earth. When you are in outer space you can float around. If you get close to the earth you will be pulled in. on the earth you could leave again in a rocket ship. However if you fall into a black hole there would be no way to get out.
