The work about the cosmos done by a combo package of renowned astrophysicists.
Richard J Gott, a person widely famous for his terrific works on time travel research and applied solution of various longevity predictions using Copernican Principles.
Neil deGrasse Tyson, one of the well known astrophysicists in the planet and also as a widely served public science educator.
Michael Strauss, an uber explorer in the field of extra galactic astronomy and observational cosmology, has made several works through spectroscopic surveys of the sky studying distant objects.
The book gives you all that you wanted to know about the world - in a more broadened perspective. It's almost everything we know about the Universe.
It's almost hard for anyone to give less than 5 star rating for this work unless the person has one of the following cases or even more than one..
1. Have Professional career/ Strong foundation in Astronomy or know most of the stuffs already prior reading.
2. Have a personal dislike for any one of the authors - most probably Neil Tyson as being the public educator is not that easy these days.
3. Don't have that much interest in astronomy and oblivious of our future frontiers in space.
In case you're a science enthusiast, I'm afraid if you don't know about this work yet. After reading the part on time travel, I'm so much optimistic though my generation probably not going to witness it.
Overall, more than a good book on Astronomy that covers from the scratch to the intricate machinery of the Cosmos.
