Death of a Black hole.

Source

Before you come to any conclusion, just take a note that you cannot destroy a black hole. But probably that black giant is waiting for you somewhere out in the universe, so be equipped to fight them.

On a serious note, is it really possible for a black hole to evaporate or even get destroyed? Why is it 

even necessary?

Black holes are very famous for their ever-lasting friendship, as they do not let anyone leave them once they cross its event horizon. Black holes are very friendly. Once in, you can never get out of their circle (EVENT HORIZON). 

But sadly, none of us would want to get near them until we have a space suit which can oppose their gravity easily.

WHY ARE YOU SO RUTHLESS?

After billions of years from now, our universe will face a black era; era of the black holes, and none of us wants to be surrounded by these black giants. 

That is the reason why it is necessary for these black giants to evaporate or probably get destroyed.

I don’t think that any creature on this earth would like to get surrounded by these black giants.

Black holes can be compared to us. We like to eat every time which results in an increase in our size. Similarly black holes do the same, they eat and increase in size, but they can too, like us, eat less and lose more in order to decrease in size. If they are really that similar to us, then do they have a temperature like us?

BLACK HOLES| TEMPERATURE.

SOURCE

Every time a black hole feeds itself, it grows larger leaving us with a very little hope of its destruction. How can a body, which has a tendency to suck I everything (literally, only the things which cross the event horizon. So do not freak out!) , can have a temperature of its own?! 

I mean, we do not know what is inside the black hole, then how can one possibly determine its temperature?

Anything which has a temperature emits radiation. Even at lower temperature, the radiations are emitted. But, black holes are very famous for their world class sucking ability. Then how can a black hole emit radiation?

Hawking Radiation is the answer to this question.

HAWKING RADIATION.

SOURCE

I will give you a very short introduction to these radiations. 

We have been told that Space is an empty space, but is it really empty?

The answer is NO. There occurs formation of virtual particles which consist of particle and antiparticle. As soon as they are formed, these two particles form a pair and annihilate each other. This happens every time.

But the negatively charged particle is a little less powerful than the positive one, which makes it weaker in front of gravity.

 

Suppose this pair appears just at the event horizon.

Being weak, the antiparticle will be sucked in by the black hole. But what about the other particle?

Yes, it escaped! And thus the particle which escaped is the radiation. Please note that this radiation is not emitted from the black hole, but from the edge of its event horizon.

And thus, we can say a black hole has a temperature of its own.

THE GRAND FINALE.

SOURCE

Coming back to the topic, can this radiation destroy the black hole?

 A simple and short answer, YES!

But if you would ask for a brief answer, I would still say yes, but with a climax.

This process might take billions of years. The emissions from the black holes will be a very slow process. 

The antiparticle, which has negative energy, will slowly decrease the mass of black hole. Thus it becomes smaller and smaller with time.

Scientists are yet not conformed as what will happen when these entities will become very small. Their predictions say that there will be an explosion. A VERY DESTRUCTIVE EXPLOSION.

Black holes are very amazing entities, very attractive, very fascinating, but please do not fall for them. Likewise, do not fall for attractive things, maybe you won’t return forever!
