Here internationally bestselling author Micho Kaku confidently hurdles today’s frontier of science, presenting the first truly authoritative exploration of the real science of tomorrow; a field normally left to writers of science fiction. He reveals the actual possibilities of perpetual motion, force fields, invisibility, ray guns, anti-gravity and anti-matter, teleportation, telepathy, psychokinesis, robots and cyborgs, faster than light travel, time travel, zero-point energy, extraterrestrial life, even clairvoyance. And he shows how few of these ideas actually violate the laws of physics. The real differences between the impossible, the unlikely and the imminent have never been so clear.
