Concise and amazing,
This review is from: Many Worlds in One: The Search for Other Universes (Hardcover)
The "Marketable idea" of the book is that theory shows that there are so so many universes than anything (even a clone of you being the president of the U.S., in other universe) has occured. But this is only a curiosity.
The book will guide you through the ethernal inflation concept, the recent discoveries about the non-zero value of the cosmological constant, how to make predictions using the anthropic principle, and the discussion between the author and Kawking about the very beginning: quantum tunneling from nothing to something, or lack of time boundary. The interested reader is provided with a very good view of the state-of-the-art in cosmology in a very light reading text.
