This book is full of beautiful illustrations and eye-catching graphics with thousands of facts about space, earth, humans, and animals. We learn about space travel and black holes. We learn about volcanoes and how we can track wind and weather patterns. We can read about the neurons in our brains and the global economy. The fastest cars, the oldest instruments, the greatest athletes, the biggest wars, the tallest trees - you can learn about it all in this book!

However, I have to wonder just how much of this book is true, and how much is just guess-work and theories. The book does not always make it clear which factoids are theories and which are backed up by empirical data. It makes me wonder how far the reader can really trust the information when it is not presented clearly. There is a page that says "Life on Earth began between 3.5 and 3.7 billion years ago, with simple, single-celled organisms called microbes." It is worded as if that statement is a fact, but it's really just a theory. One theory among many other theories regarding the origins of the universe. So what other things in this book are being worded as statements, presented as facts, but they aren't?
It seems like every science book that I read these days has this same problem. Stick to the facts, people! Or word the sentence so that it is clear what is theory and what is fact. You would think that scientists would care about being clear and truthful.
