I've read the book twice and I've seen the series based on his book. Even so, trying to keep an open mind I find that aside from what has been established as scientifically accurate, (i.e. Relativity, particle physics) this book tries to portray itself as adding to that knowledge with fanciful ideas and stories that are on par with the ancient story that a giant turtle is carrying the earth on it's back. Superstring theory is totally unproven and at this point seemingly unprovable. It adds nothing to what is already known, but it seems capable of embrassing and accepting anything new that is discovered in particle physics. It's a flexible math concept that can adapt to any conditions given, but it offers no beacon of enlightenment or advancement. Many people enjoy entertaining stories, but I prefer turtles over strings.
