Bests & Worsts Reviews from Amazon

I bought this book with an expectation to see some new ideas and new insights into the understanding of modern physics and creation of the universe. Every single idea in the book is old and have been covered before. The book simply restates those ideas without giving any new insights. If you already know "sum over histories" understanding of quantum, model dependent reality, anthropic principal, and multiple universes (multiverse) hypothesis you already know everything in the book. All these subjects have been covered in many other popular science books. On the last two pages the authors state that individual matter can not exist by itself but the whole universe can exist. This is the claim they should be spending time on to explain; however they merely cover it in one and a half pages without giving adequate explanation why that is. They simply state that gravity has negative energy therefore "done". I expected a more detailed explanation about why the universe can exist without any external energy. I am wondering if I can claim my money back from Amazon.
