In this short and sprightly book, Messrs. Hawking and Mlodinow take the reader through a whirlwind tour of fundamental physics and cosmology, concluding with an enthusiastic endorsement of the idea that our observable universe is only a tiny part of a much larger conglomeration, the multiverse. The universe we see is big, featuring over a hundred billion galaxies, but it’s still finite. The multiverse idea suggests that there are other regions, equally impressive in size, where conditions might be quite different, right down to different physical laws or different numbers of dimensions of space.

But «The Grand Design» aims beyond simply surveying hot topics in contemporary physics. It has a point—that some of the evergreen «Why?» questions of philosophy may be on the verge of being answered by modern science. Each chapter serves as a step along the path to finding such answers. The key that unlocks the them is not a new idea: It’s the «anthropic principle,» a subject of considerable controversy among cosmologists.
