Theoretical physicist and futurist Michio Kaku shows how, in the 21st century, artificial intelligence is going to become as ubiquitous as electricity, how robots with human-level intelligence may finally become a reality, and how we'll even be able to merge our minds with machine intelligence. As the challenges and choices are literally mind-bending, Dr Kaku asks how far we will ultimately go.

Theoretical physicist and futurist Michio Kaku shows how quantum physics is giving mankind the almost godlike power to manipulate the fundamental building blocks of matter. Science fiction ideas like the space elevator, teleportation, invisibility cloaks, or nanosized molecular machines might soon become a reality. But will we use our unprecedented scientific mastery wisely?

This is the story of the most extraordinary journey in human exploration, the Voyager space mission. In 1977 two unmanned spacecraft were launched by NASA, heading for distant worlds.
