The wide popular interest in Elon Musk’s recent launch of one of his own Tesla cars into space shows the extent to which space travel has again become mass entertainment as well as, perhaps, mass aspiration. It is good timing, then, for a book by the theoretical physicist Michio Kaku on the possible paths to our future as a galaxy-trotting species. . . . With admirable clarity and ease, Mr. Kaku rehearses the history of rocketry and the formation of the planets, and explains how we might colonize not only Mars but some of the rocky moons of the gas giants Jupiter and Saturn. . . . The book has an infectious, can-do enthusiasm.”
—Steven Poole, The Wall Street Journal

“Kaku is a practiced and very effective popularizer of science for a general audience; he's unfailingly interesting, with an unerring instinct for the most thought-provoking aspects of his various subjects. The sheer amount of technical scientific speculation in The Future of Humanity is amazing, and yet Kaku is in smooth, perfect control of it the entire time.”
