THE COSMOS

 Thank you Mr.Carl Sagan  for writing  the book - COSMOS  .

It gives in depth idea about evolution of life, evolution of science and  evolution of cosmos

The progress  of science right from the use of  fire to alchemy to space n nuclear technology.

How our simple naked observation to  manned n unmanned spaceship to voyage in deep vast space of cosmos, not only that but beautifully describe   how  various civilization reaches  up to  this level of homo sapiens and  mark  themselves as most intelligent spices not only on earth but entire universe because till date we do not find iota of other beings or any form of life in space .

In this lead two fundamental question arise 

Who has made this world - universe ?

How does it come into existence this world -  the universe ? 

As an individual or civilization

Always this question haunted the mind

but which one is more important question out of this two

Who or How

Both had three letters but arrangements make difference.

Similar way for any individual or civilization  out of this two point which one is  significant n given priority makes a big difference in  a progress as an individual of  community or civilization

The curiosity and habit of inquiry is very basic instinct which helps us to reach up to this mark in history of cosmos

 but don't forget the contribution of gene who gone under mutation n selectively survive n give promotion to higher species

Not only that the evolution of brain is the major contributor for our progress as species who believes in science

So basically three kind of evolution

Cosmic evolution - bigbang, galaxy, stars, planets etc

Biological evolution - just from  simple molecule to complex organic chemistry

From DNA - gene

From unicellular  to multicellular organism

From just replicating  molecule to highly intelligent conscious being

Human evolution -  from just primitive life to phase of advanced life

just running here and there as hunter  gatherers to interstellar voyager 

 human intelligence to artificial intelligence.

A book provide a unique opportunity to play with space time

Where you at one time - time travel in distant past in form history of science ,various scientists and   their  experiments , various civilization which nurture scientific approach, aptitude

While at the same time simultaneously

You travel in space from planets to stars to intergalactic space how they  have been formed and evolved  

One time it talks  about science, its inventions n  progress

Same time it look up to  humanity, human behavior its implications in our progress as species in the form of civilization

At last The book and  author also put a very significant question in front of us

We have resources n technology

But how we use it , what its outcome we saw at the time of world War

With advancement in technology we rather create heaven on earth we put ourselves in crisis we all know as species

An as the years progress this is going to be deep n deep where it may be possible we have to fly away from very beautiful earth

For that day we have to prepare ourselves not only that we have to put our resources n technology and  intelligence in right direction

So not  only we survive

But maintain our existence as species in  this cosmos

Thank you  again - Mr Carl sagon
