Me when I finished the book
Part 1: Origin of the universe
If you ever saw our earth -the complete photo- or the the Milky Way
and wonderd how it became like this why it look like this HOW we reached this point THEN this book will answer you, it may not answer you fully since there are questions until now scientist couldn't answer.
"knowing where you came from is no less important than knowing where you are going"
Part 2,3,4: The origin of the Galaxies
The final parts: Life on other planets
what are the essential elements for life which of the planets have potential to contain life
the most important is to apply "Copernican theory" .. We are NOT the center of the universe so we must stop searching for life in other planets assuming it must look like us or they must have our air and water to sustain life!
And If by a miracle- which actually happened- we found planets like Earth
"leaving us face to face (as F.Scott Fitzgerald wrote in The Great Gatsby )with something commensurate with man's capacity to wonder."
At the end of the book and as Carl Sagan liked to say "you had to be made from wood not to stand in awe of what the cosmos has done."
We shall not cease for exploration
And the end of all our exploring
Will be to arrive where we started
And know the place for the first time
