Have you ever vacuum cleaned a room before? Notice the way small bits and papers start moving towards the mouth of the cleaner?
Well a black hole works in a similar manner, the difference is that the suction is caused due to gravity rather than vacuum.
Anatomy of a Black Hole:
The Black Hole mainly consists of 3 parts:
- Outer event horizon: If you get stuck in this part you can still get out because gravity is not so strong.
- Inner event horizon: If you didn’t escape from the outer event horizon, your chance for escaping is finished.
- Singularity: The place where the gravity is the strongest, so strong that even light cannot escape from this.
So a Black Hole is nothing but empty space, rather its a great amount of matter packed in a very small area. The very possible reason why it has such tremendous gravitational pull. A Black Hole can be detected by Einstein’s General Theory of Relativity, however they cannot be seen directly by telescopes that detect electromagnetic radiations. They can be detected by their interaction with nearby matter.
And in this empty space there is so much gravity that it can literally bend the space and time around it, slowing down time. Amazing isn’t it?
A stars death is the beginning of a Black Hole.
Black holes are formed when a giant star dies, or all the fuel of the star is used up. So, basically a Black hole is formed when the dying star gets crushed under its own gravity.
In many science fictions black holes are referred to as time traveling portals, there may also come a day when we can actually form a portal and travel through time! Strange thing but definitely a thing of interest.
Another interesting fact about black holes:-
WE ARE MADE UP OF BLACK HOLES!!! Don’t believe it??
Well Black holes break down matter into sub atomic particles, these particles are used to create stars which in turn create elements heavier than helium, like iron and carbon, essential to the formation of rocky planets and life.
That’s all on the basics of the vacuum cleaners of the universe!
