I can't imagine that the stars, so far away in the sky, have anything to do with my existence. It's like a miracle! How can you know that? We'll get to that. But first, I will explain many things to you. Hubert Reeves, one of the most renowned astrophysicists in the world, explains the universe in this book to his fourteen-year-old granddaughter. She asks him all those questions that we adults don't always have an immediate answer to - for example: Where does the universe end? What was there before the Big Bang? Are there other habitable planets? Do you believe in extraterrestrials? And he answers them with the calm and considerate kindness that is characteristic of grandfathers. A charming book and a wonderful, easily understandable introduction to the fundamentals of the universe for everyone.
