Beginning Till The End Of The Universe
Hello friends, as I have promised I am going to post my topic about :-
BIG BANG THEORY, NUCLEAR FUSION, BLACK HOLE
I have told you about the big bang theory, nuclear fusion and black hole. I am re-introducing these concepts so that you have a better grip in these things
So as I have said that our universe was formed by a rapid expansion
or also you may say a explosion also.
Before the Big Bang there was no universe there was only space and point of singularity and nothing else. In this singularity was the whole universe. But we don't know how was the point of sigularity been formed we only knew that it was there.
Then gradually, the singularity started expading rapidly due to the dark energy. It is a mysterious energy and we don't know anything more about the dark energy.
During the Big Bang there was matter and anti-matter, but now there is only matter, no anti-matter. Some scientists think that while the expansion the matter and anti-matter collided with each other and destroying. As there was more matter than anti-matter, our universe was of matters.
And some other scientists believe that the anti-matter formed another universe from the universe of matter. The universe formed by anti-matters is known as the mirror world.
Then gradually, the singularity started expading rapidly due to the dark energy. It is a mysterious energy and we don't know anything more about the dark energy.

| The Mysterious Mirror World |
The laws of physics in that world may be very different than our world. But we don't know that if the mirror world exists or not. We might travel into the mirror world in the future. I will soon post about the mirror world.
Then it expanded forming a universe, the stars, the planets, the sun, cellestial bodies and we ourself came to existence. Even now our universe is expanding due to the dark energy.
If the force of gravity is more than the force of dark energy.
Then the universe will shrink into the point of singularity again and big bang may happen again forming a new univese and a new diversity of life.
Or if the force of dark energy is more than the force of gravity.
Then the universe will rip apart or it will expand and the expansion might not stop.
By this same phenomenon we can also understand the nuclear fusion happening in the stars
So let's now talk about the nuclear fusion in stars :
Nuclear fusion is a process in which hydrogen atoms in the core of the sun collides with each other giving out energy in the form of light, heat and radiation. These energy opposes the force of gravity making it stabilize.
And hence, it will not shrink or rip apart like the universe that might happen in the future.
But what will happen if the hydrogen in the star got finished????
Then there is no force to oppose the force of gravity and soon it will shrink into a black hole like the singularity of the universe
If you noticed that, the big bang and the nuclear fusion in stars have some similarities.
Now let's talk about the black hole :
As I have told you that black holes are formed when the fuel of the stars (Hydrogen) gets over, it starts to shrink and eventually forms a black hole.
The black hole has very strong gravitational force which does not even allow light to escape from the gravitational pull.
There are mainly 3 types of black holes :-
1) Supermassive black holes
2)Intermediate black holes
3)Stellar black holes
Supermassive black holes -
Supermassive black holes has billions or millions of times the mass of our sun and has a very very strong gravitational pull.
Intermediate black holes -
Intermediate black holes has 100 to 1000 tomes of the mass of our sun and also has a strong gravity but less than the supermassive black holes.
Stellar black holes -
Stellar black holes has 3 to 10 times of the mass of our sun and has a weak gravitational force than the supermassive and the intermediate black hole.
As I have said that black holes are formed when the fuel gets over in the core, so the gravity shrinks it, and pressure gets build in the core by the gravity and it explodes like a nuclear bomb forming a black hole, this explosion is called the supernova explosion or the supernova.

In this a tremendous amount of radiation and energy is released into the space.
