Sending a tiny spaceship to the nearest habitable planet at 20% of the speed of light? No problem, says theoretical physicist Michio Kaku.
Theoretical physicist Michio Kaku doesn't just hope that humanity finds its way onto other planets... he's even picked out the ones we should be moving to — Proxima Centauri B, in the Alpha Centauri triple star system. He's even suggested that the next great space exploration could happen on a spaceship the size of a postage stamp, traveling 20% the speed of light, sent by using high-powered lasers. It sounds like a wild theory, but if anyone's wild theories could come true in the next 100 years, it's probably Michio Kaku. His latest book is The Future of Humanity: Terraforming Mars, Interstellar Travel, Immortality, and Our Destiny Beyond Earth.
