"Birth of a Blackhole"

Well, I think the black hole is one of the most interesting topics in the universe and also the most mysterious. But how does a black hole born? Well, you’ll find the answer here!!!

We all must be familiar with stars. They are shiny, big, heavy, and also emit light. Now, why am I talking about stars? I am talking about them because the black hole is the final consequence of a star. A star is made with some elements like our sun is made with hydrogen and helium. As a result of the fussion reaction, hydrogen creates helium, light, sound, and heat. So, the fuel of our sun is hydrogen. Hydrogen increases and helium decreases.

But what will happen when the fuel of the sun Is over? The sun will become smaller and it will turn into a white dwarf because of the force of the electron wall. Now let’s talk about a star 1.5 times heavier than our sun. Its fuel will also finish someday and it will start to shrink. It will break the electron shield and will be smaller than a white dwarf.

But at a particular point, it’ll also stop shrinking because of the force of the neutron wall. Then, we will call it a neutron star. Ok, now let’s talk about a star which is 3 times or more heavier than our sun. It will also face the same situation and start shrinking. It will break the electron and neutron shield and will be more smaller than a neutron star! At a point, it’ll become so small and heavy, that it will explode. This explosion is called a supernova. After a supernova explosion, it will turn into a black hole. That’s how a black hole is born.
