Most of the concepts presented, very abstract, such as the expansion of the universe, the fusion of hydrogen, the concept of the Big Bang, dark matter, dark energy, etc ... can not be treated by single reading this excellent book. This book built as a result of questions asked by the child so the initiative of dialogue and answers popularized by a field of professional represents a situation that has nothing to do with the child who reads alone in his office or in his room, and this book will be completely "thrown" at the first difficulty understanding. Reading this book can be addressed, as indicated by its author, a child from 14 years, but the questions that will spark in him will not be able to find an answer, either in the traditional family, or even in the school of her age. The answers and explanations can only come from someone who does have the current theories of the universe in its past and future phases, which is more capable, as is the case of Hubert Reeves, popularize without too much strain these theories and observations. In conclusion I would advise rather this excellent book to adults would approach for beginning the Universe concepts. And given the sale price it costs nothing to try. Good reading.
