I would recommend this book to anybody on the planet. Religious or not you may have asked yourself a lot of these questions gone over in this book but this isn't an answer. It just helps you more understand the question that is you are asking.
This book blew my mind and my imagination. As an animator and science lover I was very impressed with comprehensive the subject matter is. My imagination sparked as he spoke about the future of our universe as well as the possible other universes. I would recommend this book to anyone who wants to learn, whether they are science literate or not. After all your brain is most happy when it learns something new.
Not to knock Krauss, but there were times I felt he needed more passion in his words. It would have made it that much more enjoyable to listen to.
