Physics of the Impossible is 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.

In AD 2600, the human race is finally beginning to realize its full potential. Hundreds of colonized planets scattered across the galaxy host a multitude of prosperous and wildly diverse cultures. Genetic engineering has pushed evolution far beyond nature's boundaries, defeating disease and producing extraordinary spaceborn creatures. Huge fleets of sentient trader starships thrive on the wealth created by the industrialization of entire star systems. And throughout inhabited space, the Confederation Navy keeps the peace. A true golden age is within our grasp.

But now something has gone catastrophically wrong. On a primitive colony planet, a renegade criminal's chance encounter with an utterly alien entity unleashes the most primal of all our fears. An extinct race which inhabited the galaxy aeons ago called it "The Reality Dysfunction." It is the nightmare which has prowled beside us since the beginning of history.
