That's Impossible!

The focus of this episode shines on the death rays and energy weapons which have been used in the old science fiction movies, including laser cannons capable of downing a plane and nuclear missiles.

An examination of the efforts being used to prolong life, including growing replacement body parts in a lab, creating microscopic robots which can eradicate deadly diseases, and reversing the aging process.

The power to use tornados, hurricanes and the deadliest weather as weapons of war may now be possible. We'll investigate reports that weather weapons are in development and reveal the technology that--in the future--could turn hurricanes, earthquakes, even tsunamis into some of the most powerful and plausibly deniable weapons of mass destruction the world has ever seen.

Robots that think, move like humans and fight our wars--Real Terminators--may now be possible. At leading universities and covert government labs, robots are now being developed in man's image; cyborgs with superhuman strength, machines that may eventually be able to make decisions, even kill on their own. But will these very robots designed to protect us ultimately turn on their masters?

The power of true invisibility may now be possible. This episode investigates classified reports that the British military recently tested an invisible battle tank, examines the scientific breakthroughs that may soon give us all the power of invisibility, and witnesses a remarkable demonstration of an invisibility cloak that makes a man vanish.
