This is mostly a book about cosmology (meaning there’s not much about galaxies, stars or planets) and it covers the usual topics for books like these, such as: the expansion of the universe, the cosmic microwave background, the big bang, the geometry of the universe, inflation, dark matter, dark energy, black holes, time, life in the universe and the fate of the universe. I have read several other popular science books covering similar topics, but I think this is the most popularized version of it. The book is written in a simple language and very pleasant to read. It will therefore be accessible to most people.
The book is divided into many short chapters, covering one main idea at the time. I think that is wonderful, as the topics can be a bit heavy and theoretical at times. To be honest, this book actually reads as a book about astrophysics for people in a hurry, compared to the book that actually bares that name (and doesn’t live up to it, in my opinion).
The book covers a bit of history without drowning in it, as I feel that other books sometimes do. I think Davis does a great job of sticking to the information that is most necessary to discuss the topic at hand, keeping this book short and sweet. On occasions it’s too short and sweet, but I think this book is a very nice introduction for people getting into these topics for the first time. If you are already familiar with these topics, there might not be much to gain from reading this.
