How do you build a Tardis? What are the secrets of teleportation? Could Cybermen take over the world? Is telepathy possible - even for an alien? Will extra-terrestrials one day visit planet earth on their travels through the galaxy? Can a robotic dog catch a cold? Take a journey with the Time Lords as Michael White guides us through the real science behind Doctor Who. Here he shows us how one of the world's best-loved science-fiction programmes is actually based on genuine theories - some of which could soon become a reality. Drawing on the latest discoveries, on shows from Star Trek to The X-Files and films like Twelve Monkeys and Contact, he asks (among other things): is time travel possible through a wormhole? What are the dangers? Could we make contact with life on other planets? How could aliens get here? And how soon until creatures like the Daleks become a reality? He also looks at areas as varied as crystal power, robotics, shape-shifting and multi-dimensions, not to mention the mysterious science of 'chameleon technology' currently under study by major military research organizations. We even discover how, with the use of cybernetics to replace body parts - or maybe regenerate whole bodies - Doctor Who could hold the key to eternal life. A book for avid fans and the merely curious, A Teaspoon and an Open Mind reveals that reality is even stranger than science fiction!
