The Hidden Reality: Parallel Universes and the Deep Laws of the Cosmoswill join The Elegant Universe and The Fabric of the Cosmos, two bestsellers that have explained string theory, the nature of space and time, and modern physics in general to millions of readers.
The third book will be dedicated to cosmology - especially to the multiverse and eternal inflation. While many ideas attached to this topic are demonstrably wrong while others are arbitrary i.e. probably wrong and the anthropic people are spreading lots of defeatist emotions, I am confident that the new book will be very good and will present a convincing picture.
The Hidden Reality has already received 9 reviews at amazon.com - where you may also see a preview of the book. 8 of them are 5-star reviews and 1 of them is a 3-star review.
While the book will probably present the "most outrageous" stuff that the "critics" of string theory usually attack - and I feel uncomfortable with some of the stuff myself - don't expect the critics to launch a strike against the book.
After all, the main "critic" who is the informal king of this whole aggressive crackpot movement is employed as a useless shameless parasite and a computer administrator by Brian Greene himself. So with his lack of basic morality, he is just licking Brian's buttocks all the time, despite the fact that he is pouring vitriol on many others for much less serious "sins". There also exists an explanation why Edward Witten - the very king of string theory - gets a similar special, favorable treatment by our "critic" but this blog entry is not primarily about these matters. However, throwing away the taxpayer money is often a dirty business.
