In three parts he explores the technologies that can make this possible. The laws of physics are clear sooner or later we will face global crises that threaten our very existence. (p.6) Discussing other great challenges we’ve faced through history, he writes:īut now we face perhaps the greatest challenge of all: to leave the confines of the Earth and soar into outer space. He is convinced that, whether through physical causes ranging from cataclysmic volcanoes to asteroids or the final death throes of the sun, our planet will become unlivable for human beings–if we do not accomplish this first through human causation as in nuclear holocaust or global warming. Kaku’s argument for the necessity of becoming a multi-planetary species is rooted in the priority of the survival of the human species. This, the latest of his books, explores that idea, it’s necessity, and the technological advances that could make this possible.

He is also a riveting, passionate speaker who believes, along with others like Elon Musk, that we must envision becoming a multi-planetary species. Michio Kaku is a theoretical physicist studying string theory at the City University of New York, and the author of a series of best-selling futurist works based on his knowledge of physics and other fields. Summary: An exploration of the possibility and necessity of humanity becoming a multi-planetary species, and the revolutions of technology necessary to realize that future.
