This is an enchanted book about reality bounded by the spiritual realm, science, and science fiction. Science fiction because such sciences are simply processes we are yet to understand or instruments yet to be discovered or created. There are some sciences I believe even transcend human understanding. All these make up our world in different dimensions of reality. Understanding gravity in its strongest and weakest point is important in reading this book, or then again, you could just sit back and enjoy how entertaining this book is.
