How to destroy a blackhole

 If you want to destroy a black hole then with current technology it does not seem possible.

For that, you have to sit on the chair and wait for the self evaporation of the black hole, but it may take millions to billions of years.

1. How do black holes evaporate?

Black holes are those monsters of the universe which swallow all things in their surrounding, it may be planet, sun, star or even another black hole.

We know that black holes emit radiation which is known as Hawking radiation.

2. What is Hawking Radiation?

We know that always pairs of virtual particles become in space and these virtual particles destroy themselves.

There are two particles one contains a positive charge and another negative.

When we talk about empty space it doesn't mean that place is completely empty, these virtual particles remain there.

Means particle ( +ve energy) and antiparticle ( -ve energy).

Pairs of these virtual particles also become near the event horizon of the black hole.

When these pairs form near the event horizon of the black hole ( outside), then negative energy particles go inside the event horizon due to immense gravity but positive energy particle escape the gravity effect of the black hole near the event horizon.

“These pairs of virtual particles do not become inside the event horizon but outside it (On the edge of the event horizon)”.

3. Why do only antiparticles go inside the black hole?

Because they do not have enough energy to counter the gravity effect of a black hole near the event horizon means they do not have sufficient energy to escape the gravitational region.

Because nanoparticle is already negative charged.

But on the other side, positive energy particles have sufficient energy to escape.

And these positive energy particles are known as Hawking radiation.

4. Death of black hole:

When a black hole emits this radiation there size also decreases because negative energy goes inside it.

As less the mass of a black hole more will be the radiation emission.

In this way, black starts losing its mass, and at last two things may happen.

I) There may be a big blast that occurs when black has left very small mass and everything releases into space which has been swallow by a black hole. And the death of a black hole occurs.

II) Till vanishes, the black hole may evaporate and all energy releases into the universe in the form of radiation.
