Formation of Earth


How earth formed ? 

A few Billion years back  there was a blast  happen in space 
it was an accident its a  Bigbang 

About a half a million years after the big bang, the cosmos
 began to cool, as it cooled, the hot subatomic particles that 
constituted the early universe began to slow down and stop 
colliding with each other long enough so that protons, neutrons 
and electrons could form. The universe cooled further and the hot
 particles slowed further still allowing these particles to stay together
 long enough to create atoms.




The universe was nothing but a cloud of hydrogen and helium. 

Slowly, the universe continued to cool and structure begins to
 present itself within this universal cloud. From small disturbances 
woven into space time the galaxies begin to collect, tiny variations
 in the primordial universe became the web that collected galaxies
and gave the cosmos its form.


hydrogen  gas come   to  one small place  its  the  formation of universe


These galaxies become distributed along these structures, 
dancing within their gravitational fields, forming giant tendrils
 reaching out across the span of eternity.


Until just a few short decades ago, astronomers thought 

the universe was static and unchanging, we didn't even 
know there were other galaxies until the 20th century. 
Thheavens was a place of constancy and uniformity,
 the stars and planets were always there and they always
 would be - steady and unchanging. Instead we have 
learned that the cosmos is a seething cauldron of activity, 
as alive and vibrant as any one of us.


Stars are born, shine and explode; 
stellar 
winds blow huge storms of gas across 
interstellar space; black holes devour all 
they touch; galaxies collide with each other, 
spraying stars into eternity.

And space time itself grows larger by the minute.


The universe is far from a static place. As giant stars explode
 after living out their lives, they stream out the elements of life, 
carbon, oxygen, nitrogen, iron, all the necessary components 
for planets to form and for life to begin. We are more connected to
 the universe than we know, the stars are our ascendants (forefathers),
 we are their progeny.
