What is the Black Hole?

"Black hole is the place in space where no laws of physics work. It's gravitational field is very powerful. Nothing can be saved from its vibe even Light also."

Albert Einstein has said that the gravity of anything wraps the space around it and gives it a curve shape.

Albert Einstein gave the theory of relativity in 1916.

Black hole belongs to the entire Universe, is the most dangerous celestial body that swallows everything that comes in its area, even the light, whose speed is 2.99792458 x 10 8 m / s i.e. second at 3 lakh km That is, light also has no effect. Reason is too much gravity, which distorts both space and time.

How Black hole creates?

Due to the intense heat emanating from nuclear fusion, the star stays in gravitational equilibrium, so when the star is exhausted by hydrogen, the star starts to cool down slowly and then exhausts its own fuel 1.4 times the mass of stars, which cannot handle themselves against their own gravity, in such a situation there is an explosion inside these stars, which we call supernova or mahanova.

After this explosion, if any denser residue of that star survives, it becomes a neutron star with very high density. And due to the immense gravitational pull in such stars, the star starts to compress and It narrows to a certain critical limit at the end of compressive and due to this extraordinary contraction, its space and time also deform and due to the existence of space and time in itself is lost. He would become invisible and this is the invisible object We have what we call a black hole.

Types of Black Hole.

So far, astronomers have identified three types of black holes:

1. stellar black holes.

2.supermassive black holes.

3.intermediate black holes.

1. Stellar Black Hole:

Stellar black holes are formed from massive stars. As a star ages, there is a battle between gravity pushing inward and the radiation pressure due to nuclear reactions inside the star pushing outward. When these stars die, their outer region is mostly made up of iron. The radiation pressure causes a massive explosion which we call a supernova. This explosion sheds the outer shell of the dying star leaving the core. Gravity then collapses this core into a singularity but only if the core was massive enough (greater than 10 times the size of the sun). The result is what we call a stellar black hole.

2. Supermassive Black hole:

Black hole that form at the center of the galaxy and are very large and huge density are called supermassive black hole. the mass of such black hole is millions of time greater than our sun.

there is also a supermassive black hole in the middle of the galaxy whose density is about one million times than our sun.

3. intermediate black hole:

Also called Primordial black hole. Finally, there are micro black holes. Never actually observed, these black holes have masses that are smaller than the sun. The speculation is that these black holes were formed during the Big Bang.
