It has some good content, however it is filled with a lot of unnecessary questions and puns. Tough to stay focused while reading.I would compare it to someone that has prepared a 15 minute speech, then is asked to speak for an hour.

Tyson possesses great talents, both as writer and astrophysicist, and both are on good display in this book. It is an amazingly easy read about incredibly complex phenomena. And, while summarizing much of what we have learned about the universe, it humbly and forthrightly assesses how little we still know.

I enjoyed Tyson's tour through cosmology. I have read several books over the past few years on the physics of the universe and Tyson's book is a lovely "condensed version" of my previous readings. Tyson has a straightforward, folksy writing style that entertains as it informs. If one is looking for a complete documentation of the current state of cosmology, this is not that book. If one is looking for an introduction to this dense topic, Tyson's book is a very good starting place.

I needed to “cleanse my palate” after binge reading a fantasy series. I decided to step as far from fantasy as possible, so I ventured into the far more complex realm of…Fact.Astrophysics, to be precise.What’d I learn?I learned the universe is much bigger than I can comprehend, and we puny humans are much less significant to the universe than we imagine.I learned I’m glad there are people who are good at Astrophysics, because I’m notMostly, I learned that Astrophysics is really (Really, REALLY) complicated. Even having Neil deGrasse Tyson spell it out for me couldn’t get topics like quantum mechanics, prolate spheroids, dark matter, or E=MC2 to be more than curiosities beyond my reach.Getting through the book was worth it just to get to the last chapter, where Neil deGrasse Tyson brings the “our universe is so big and we are so insignificant” talk to a climax with some great comparisons. For example…Did you know there are more molecules in a cup of water than there are cups of water on Earth?Of course you didn’t. Because you’re not an Astrophysicist.Instead of feeling small, however, I was left feeling part of something very, very grand.Some call it science. Some call it God. I call it both.Interested in Astrophysics but clueless about Astrophysics? This is the book for you. You’ll still be clueless, but you’ll feel okay being clueless once you get a sense for the overwhelming complexity involved in with the physics of the universe.It’s a big place.Happy Reading.

I have a couple of degrees in the biological sciences but have loved all the natural sciences since childhood. That said, this is one of the best books of its genre for anyone who has similar interests.....layman or PH.D. Although I have never been trained in physics or astronomy, both have become strong interests that I have avidly pursued in my lifetime. This book is a wonderful, easily digestible summation of the state of man's knowledge of the origins of the universe that we inhabit.....to date. Highly recommended.
