An interesting read, with some excellent explanations of physics. My quibble is how heavily the author leans on a flavor of the Anthropic Principle which seems to put the cart before the horse. In this Panglossian paradigm, the universe has been 'fine-tuned' for our benefit. It seems to me that reverses the logical cause and effect- since we have evolved in this universe, obviously the physical constants and laws must permit our existence. We are fine-tuned to our universe, not vice versa. The author ultimately concludes that there is a 'Landscape of possibilities, populated by a megaverse of actualities', and that like Laplace his hypothesis does not require a god, but that seems rather at odds with his prior explanations of the anthropic principle.
