The Grand Design

Stephen Hawking and Leonard Mlodinow's new book "The Grand Design" was released on Sep 7th 2010. It starts with the explanation of the lonian greeks idea of working of universe based on the laws and not on the will of God. It explains the latest thoughts about model-dependent realism (the idea that there is no one version of reality), and about the multiverse concept of reality in which there are many universes.

The central claim of the book is that the theory of quantum mechanics and the theory of relativity together help understand how universes could have formed out of NOTHING.
The authors write:

Because there is a law such as gravity, the universe can and will create itself from nothing. Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist. It is not necessary to invoke God to light the blue touch paper and set the universe going.

The authors explain, in a manner consistent with M-Theory, that as the Earth is only one of several planets in our solar system, and as our Milky Way galaxy is only one of many galaxies, the same may apply to our universe itself: that is, our universe may be one of a huge number of universes.
The book concludes with the statement that only some universes of the multiple universes (or multiverse) support life forms. We, of course, are located in one of those universes. The laws of nature that are required for life forms to exist appear in some universes by pure chance, Hawking and Mlodinow explain.

The book is available on amazon, landmark and other online stores for Rs.419.
