"An exploration of some of the deepest questions about our place in the universe"--From publisher.

What is our place in the universe? -- How do we know what we know? -- How did the universe get to be this way? -- How old is the universe? -- What is the universe made of? -- What is life? -- Are we alone in the universe? -- How did it all begin? -- How will it all end? -- What does nothing have to do with everything?.
