The Big Bang Theory-Formation of Universe

The Big Bang-Formation of Universe

Hello Friends, in today's blog, I would like to talk about the biggest theory of science and that is The Big Bang.

 So today I will tell you what this Big Bang theory is.

What is the Big Bang Theory?

Have you ever thought that the universe on which you have been living for so many years, how it was composed and where all the events have happened, where did they start?

 To know how the universe started, we have to go back 13.8 billion years.

This is our eternal universe, everything is buried in this.

There is no existence of time here, but the world that we know is about to begin. Now, due to some reason, an universe smaller than the size of an atom came into existence.

 This universe spread in the second half of the world.
 And this is what we call The Big Bang.

UNIVERSE'S BORN

The blast that has taken place at this time is pure energy. This energy spread in a complete way only then space was born and time came into existence. This energy continued to spread millions of years in this way and matter was born, Billions  Forms of small subatomic particles that we call atoms were formed.
 Quarks, Protons, Neutrons and Electrons are formed.

 There were actually 2 types of things were formed:

1. Matter
2. Anti-Matter

When Matter and Antimatter meet each other, they destroy each other. But unfortunately, Matter became a little more than Antimatter.  So that's why a Matter survived and there was little else.

 Then everything cooled down as the shell of that Matter was blasted.

The Big Bang

Then due to a force all the atoms started connecting with each other.

 This force is no other than gravitational force.

 Initially, atom of Hydrogen used to exist

Then the gravitational force started compressing the atom of Hydrogen. As the temperature of a place went above 1crore degrees while compressing, then a process started which we called Nuclear Fusion. 

Due to which more energy came out and at the same time the universe came out.  The first star came into existence.

 And millions of stars came into existence within millions of years.

Yes, these are the stars you see at night.

Due to the gravitational force, all the stars started approaching and they started appearing in groups according to their size and shape.  In this way, Billion stars started getting confused and this is what we call Galaxy.

And this is how billions of galaxies were born. And out of one of this galaxy where we live is The Milky Way.

Formation of Planets

There are billions of stars present in The Milky Way , but there are some dust remains and this dust is flowing in space.

But within thousands of years, the gravitational force started its work.  The dust that was left began to come closer due to gravitational force and in the same way different planets started to be built.

Within this all planet, one rocky planet also formed and that planet is none other than is Earth.

Earth

Formation of Sun

Now the remaining Hydrogen atoms started connecting due to gravitational force. And so a small star started to form. So the temperature increased that Nuclear fusion started and that's how the sun was born. 

A strong solar wind. And similarly dust particles went out of the solar system. And 8 planets remained in the solar system.
