Universe at its best with the big bang explosion

 

OUR UNIVERSE

The universe was based on Big Bang as an unimaginably hot, All the potential of the universe, time, space and matter was concentrated in a singularity.

 According to the standard theory, our universe is around 13.7 billion years ago.

  Inflation took place in the first few moments after the big bang when the universe doubled in size about 100 times almost If the universe didn't inflate, then you can't explain why the universe is so smooth without having faster than light travel.

 In inflation the four fundamental  forces split into individuals are:

 GRAVITY, ELECTROMAGNETIC, STRONG and WEAK NUCLEAR FORCE.

 Before inflation, all these four forces  are bind to each other to form a super force

. After the expansion of the universe, the temperature of the universe decreases drastically

(Temperatures cooled from 100 nonillions (1032) Kelvin to 1 billion (109) Kelvin).

 After this decrement, the universe is cool enough for atomic nuclei to form, 

the element hydrogen is formed, 

and some hydrogen atoms fuse to create helium.

380,000 years later the light travel through the darkness, 

and after billion years later stars started to take shapes

 with producing heavier elements like nitrogen, 

oxygen and carbon.

 After 9 billion after the big bang matter and gravity combines to form a perfectly typical star,

 pressure creates heat at its core and this heat triggers the thermonuclear fusion and a star is born after this gases and dust revolve around it and form planets and moons and then the solar system formed.

 And same as our solar system also formed and our earth is formed around 4.5 billion years ago.

Discoveries made till NOW!!!

AT THE BEGINNING everyone knows that earth is the centre of the world,

 sun and moon revolve around it.

 But then a man named NICOLAUS COPERNICUS

 comes with a discovery that stuns everyone by saying that earth is only a planet among others that is revolving around the sun.

And given his theory named as 

HELIOCENTRIC THEORY.

 And then comes JAHAMES KEPLER

 with his three law that describes the nature of rotation of planets around the sun 

and also told us that the path

 taken by planets is elliptical.   

Then GALILEO comes with his telescope and observe the night sky and collect valuable data including the discovery of the 4 largest moons of Jupiter and he has been called the

 

“Father of Observational Astronomy”. 

Light travel with such a high speed that it was very difficult to calculate it.

 But a Danish astronomer OLE CHRISTENSEN ROMER became the first person to do it.
