I am a layperson, to say the least, but I yearn to know more about our fascinating universe. This is by far the most entertaining book I've ever read regarding the subject. I can't stop thinking about all the wonderful concepts that Adams and Laughlin discuss. I'm going to read it again just as soon as my Dad returns it to me! Perhaps I'll just buy another copy and use one as a loaner. I highly recommend this book to every single person, regardless of educational background, who enjoys scientific journeys of the most extrordinary kind.
