How was Earth formed??? first let me talk about Big Bang .............
What was Big Bang Theory ???
Well , you see Big Bang is not a theory rather it is an application of a theory - the Theory of Relativity .
Theory of relativity in short says that speed depends on the eyes of the observer.
Simple huh ? now look deeper into this.......
Scientists and astronomers first noticed that all objects in the cosmos are moving away from each other. For instance stars , galaxies move away from each other .
That means that the objects must have originated from a single point. Hence the Universe is expanding and it originated from a single point.
Thats it ! This is the so called Big Bang Theory .
How was Earth formed ???
Well I am a class 10 student I know only this much :
After the Big Bang there was a time period ( not sure when exactly ) when there was no light at all. This age was called the Dark Age.
After the Dark Age , the stars were formed . Then the galaxies , black Holes , then the planets .
When the planets were formed , they had a huge temperature and it took several billion years for Earth to cool down.
During these years it may had been hit by several asteroids and the Earth was eventually formed with a safe atmosphere and it is the most unique planet in the whole Universe which succeeded to support life within it !
How did life start ?
My words "Life is nothing but a combination of chemical reactions and energy"
What is life ?? Its just D.N.A molecules and energy ....................
It all started when Earth cooled down and the first ever born creature should be a virus then an anaerobic bacteria and then evolution change birth of new species and so on....................
Extra curiosity : How did Big Bang Start ?
It just started with quantum fluctuations
It was nothing : 0
From 0 arised infinity
0 = + infinity - infinity
Just think that + infinity is the mass of the whole cosmos
And - infinity is the energy of the cosmos
This was the basic theory of origin of the Universe ............
Hope it helps ( I know only 2 or 3 people will read this ...... )
