Read on, and find out... This book is suitable for both adults and for children. It is written especially for those who want to discover how the universe works without delving into complicated mathematics. Although the story in this book is fictional, the laws of physics underlying it is real: Our universe really is held together by four fundamental forces, and this this book explores each them in turn. By travelling to other universes outside our own, the reader can safely observe both the obvious and sometimes bizarre consequences that would result if ours laws of physics were tweaked.
