Except for the first few pages, which I found difficult to follow, the book is an extraordinary,enlightening and entertaining journey into some understanding of the universe within which we live. An inviting primer that may lead the reader to greater study of our world. Neil Tyson's explanations can easily entice one to seek more information and knowledge as a reader of mystery novels would seek more clues. A great book.

Understanding that this is an introduction into the study of the physics of generally speaking, literally everything. There is a LOT of information in this book, and Neil DeGrasse Tyson, does an outstanding job of condensing down and translating this information into language for the astronomy layman. Again this is Physics, and while Neil DeGrasse does a great job of explaining the universe, in a way that I believe (to his awesome credit) only he can do. It is STILL physics.... Slow down, take your time and absorb this vastly condensed, concentrated mass of information, in order to get the most out of the read.

I haven’t read the other Tyson books mentioned by other reviewers, so for me, (a mere mortal, not a mathematician) the material was fresh, illuminating, and simply wonderful. Dr. Tyson’s ability to summarize complex theories and translate them into a digestible cogent whole is phenomenal. I neither have the time, desire, proclivity or ability to understand complex mathematical formulas, so having a work that rendures them understandable, and at the same time, provides a sense of wonder fills my heart with gratitude beyond words. Dr. Tyson is the embodiment of a national treasure. Thank you!

Mr Tyson made it easy and fun to learn about possibly the geekiest information that exists. I had a long-standing curiosty about all things that make up the universe, but no time/ability to obtain a PHd. He put the essential concepts, terminology, history, and challenges within my grasp.

Not really sure if people in a hurry can understand it without some sort of background. It took me two - three reads for chapter 1 to understand it, I dont think I was not knowledgeable, I'd like to think I am a little bit less than average.. Still very hard read for me. Really doubt people in a hurry can understand the book entirely. If so, you're awesome! If not, don't worry, I am there with you! lol
