What a great book! Tyson is one of a rare breed, a genius in astrophysics with a sense of humor that can explain very compex topics so that even a toad could understand. Ok, maybe that is an exaggeration but you get my meaning. This book only tickles the surface of current theory and knowledge of the universe, but it does it in a way that makes you hungry for more. Tyson has been called a rock star of science and rightly so. He knows how to draw you in and get you excited to learn more. But he is not too full of himself as you will see in the last chapter.
