What If? combines humor and actual scientific evidence into an interesting and fun reading experience. The book describes a series of reader submitted questions and the author, Randall Munroe, tries to answer them using research and intellect. It goes from bizarre topics such as throwing a baseball at the speed of light to seeing how long it would take for two immortal people to find each other on random parts of the Earth. This book will keep you interested and very entertained throughout and will push the limits of silly scientific reasoning for silly questions. If you love science and are just as curious as the people who submitted their questions, this book is for you. - PPL TAG
