Our Mysterious Universe

    “The  Big  Bang  Theory”

Our world is so beautiful, but in this world everyone is busy in their daily life, you have been living in this universe for so many of the years but have you ever thought how did it started ?? how many incidents happened ?

Our scientist have discovered that our universe is expanding, it is expanding every second that you can think of. It is about 73 km per second. 

Fig 1.1 BigBang Explosion!!

  # How it just began??

So to know how this universe began, we just have to stop the time and go back. Let's go back a little bit about 13.8 billion light years ago, The Infinite Universe that we see today was concentrated in a dense hot point [•] like structure full of infinite energy called singularity which was smaller than the size of the atom.    (as in the figure 1.2) . 

Fig 1.2 The Atoms. 

There is no existence of time but at present the universe we know had a beginning.                Due to some mysterious reasons the heavily dense point like structure smaller than the size of  an atom came into its vast existence, within a millionth of a second this universe from a small dense hot point spread into its existence and we call this the biggest theory that is__

                           "The Big Bang Theory".

# What happened after the explosion?

This explosion if you can imagine is all about energy that is pure energy.  This energy  spread in vast and at this particular point space and time came into their existence and this pure energy was in such a massive amount that it went on spreading for crores and crores of years in these years it went cooled down and because of this energy formation of matters takes place. 

Billions of small particles that we humans identify as atoms, quarks, electrons,protons and neutrons were formed.

 Actually two kind of things were formed half was matter and other half were anti-matters when they face each Other they cancel out each other. When all the matters and anti-matters were destroyed. 

Fortunately a tinny amount of matter survived, which is what we see in the universe today and what we are! This one particle of matter explode. After this explosion everything went cooled down and on many dust like particles and asteroids an unknown force was acting by which each atom, dust particles, rocks, gases and giant asteroids were combining, colliding and attracted by this force which was & is  non other than the_"gravity".

(The dust particles in the solar system collided and formed larger bits of rock, which eventually formed the planets.)

Fig 1.4 Gravity into it's existence

     # Formation  of  Planets  and  Stars

At first, there were many Hydrogen atoms, In this universe at many places gravity was compressing these H ( hydrogen) atoms, during this when the temperature was at 1 crore degrees Celsius a process was taking place that we know as 'Nuclear Fussion' it produced and radiates massive energy and this was the first star formed.               

                                                                                

 Fig 1.5 Formation of the first star  

                     

                             # Formation of Galaxies

In these billions of years billion amount of stars, gases, dust, black holes and dark matter were formed and these are the stars which we observe in the sky and feels curious to know about them.

These stars, dust, gases, asteroids and the planets due to gravity lives together in a group  and this collections of all the stuff like stars, asteroids gases, dust particles and planets is considered 

as a - "Galaxy".

Like this if we talk about present, 13.78 billions of years have been Passed and within this time period scientists estimates that a 'billion to trillion' of Galaxies have been formed and discovered which are now into their existence and from    these deep oceans of Galaxies one is none other than  "The Milky Way"  the Galaxy in which we live today but It was never how it looks today.... 

 Fig 1.6 Our Milky Way

In this Galaxy still there were many dust particles, gases and asteroids. In thousands of years , gravity combined and collided these small asteroids/Rocks and mixture of gases & dust particles with other big asteroids and existing small planets and give birth to many giant gaseous planets like Jupiter, Uranus etc including rocky planets like Mercury, Venus and this is not shocking anymore that one of them is our beautiful planet "Earth".

But the Earth wasn't the same as it looks today the Earth also has its own journey  from a giant asteroid/Rock to this latest human civilization......

             

   HOTS ( High Order Thinking Skills )

 1.) Why Life 🧬 is only possible on Earth out of the        8 other planets?

2.) How does Earth's moon Formed?

3.) The distance b/w Sun and Earth is neither too          close nor too far, suitable conditions? Is it                  Random or a coincidence?

4.) Why the Earth's axial tilt is 23.5 degrees which        causes different climate shift ?

5.) Was the moon part of the earth or derived                from earth? 

         _ Find the solution of these 5 Hots questions.

Just think that if there was a single silly mistake, would this entire universe be formed and would we discussing about  the beginning of the Universe ?
