The first major work in nearly a decade by one of the world's greatest thinkers.
The Grand Design 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. There are new ideas about the top-down theory of cosmology (the idea that there is no one history of universe, but that every possible history exists). It concludes with a riveting assessment of m-theory, and discusses whether it is the unified theory Einstein spent a lifetime searching for.
