A fascinating exploration of the science of the impossible—from death rays and force fields to invisibility cloaks—revealing to what extent such technologies might be achievable decades or millennia into the future.

One hundred years ago, scientists would have said that lasers, televisions, and the atomic bomb were beyond the realm of physical possibility. In Physics of the Impossible, the renowned physicist Michio Kaku explores to what extent the technologies and devices of science fiction that are deemed equally impossible today might well become commonplace in the future.

From teleportation to telekinesis, Kaku uses the world of science fiction to explore the fundamentals—and the limits—of the laws of physics as we know them today. He ranks the impossible technologies by categories—Class I, II, and III, depending on when they might be achieved, within the next century, millennia, or perhaps never. In a compelling and thought-provoking narrative, he explains:

· How the science of optics and electromagnetism may one day enable us to bend light around an object, like a stream flowing around a boulder, making the object invisible to observers “downstream”

· How ramjet rockets, laser sails, antimatter engines, and nanorockets may one day take us to the nearby stars

· How telepathy and psychokinesis, once considered pseudoscience, may one day be possible using advances in MRI, computers, superconductivity, and nanotechnology

· Why a time machine is apparently consistent with the known laws of quantum physics, although it would take an unbelievably advanced civilization to actually build one

Kaku uses his discussion of each technology as a jumping-off point to explain the science behind it. An extraordinary scientific adventure, Physics of the Impossible takes readers on an unforgettable, mesmerizing journey into the world of science that both enlightens and entertains.

ADVANCE PRAISE FOR PHYSICS OF THE IMPOSSIBLE

“Science and science fiction buffs can easily follow Kaku’s explanations as he shows that in the wonderful worlds of science, impossible things are happening every day.” —Publishers Weekly

CRITICAL ACCLAIM FOR PARALLEL WORLDS

“A wonderful tour, with an expert guide, of a cosmos whose comprehension forces us to stretch to the very limits of imagination.” —Brian Greene, author of The Fabric of the Cosmos

“A highly readable and exhilarating romp through the frontiers of cosmology.”

—Martin Rees, author of Our Cosmic Habitat and Our Final Century

MICHIO KAKU is the Henry Semat Professor of Theoretical Physics at the Graduate Center of the City University of New York. He is the cofounder of string field theory. He has written several books, including Parallel Worlds and Beyond Einstein, and his bestseller, Hyperspace, was voted one of the best science books of the year by the New York Times and the Washington Post. He is a frequent guest on national TV, and his nationally syndicated radio program is heard in 130 cities. He lives in New York City.
