Every starship needs armor to protect it from asteroids and enemy attack- Dr. Michio Kaku reveals how cutting edge science could be used to create force fields that might one day save our space craft from an alien onslaught.
Defying gravity and hurtling through space: the flying saucer is the ultimate science fiction vehicle. Using cutting-edge research and theoretical physics, Dr. Michio Kaku reveals how one day we could all be using the aliens' favorite mode of transport.

With exclusive behind-the-scenes access, Horizon follows the highs and lows of an extraordinary story in particle physics. In June 2015, teams at CERN started running the large hadron collider at the highest energy ever. Rumours quickly emerged that they were on the brink of a huge discovery. A mysterious bump in some data suggested a first glimpse of a brand new particle that could change our understanding of how the universe works. A new particle could hint at extra dimensions and help us understand the very beginning of the universe - but first the team has to find it. Horizon follows the scientists as they hunt for the elusive signals that would prove if there is a new particle or if it is just noise from their machine.
The human race has succeeded in explaining nearly everything in this universe using mathematical formulae. Yet there is one place that remains shrouded in mystery -– black holes. Physicists believe that if they could discover a formula that explains the center of black holes, the last remaining mystery of the universe could finally be unraveled -– how the universe came into being. Their attempts have been mired by unforeseen pitfalls but with the development of superstring theory, physicists have arrived at a formula that could finally end their century-long search. What the formula described was a world beyond our wildest imaginations. This is the incredible story of physicists like Einstein, Hawking and the superstring theorists who have endeavored to solve the mystery of the origin of the universe.
Richard Feynman was one of the most brilliant theoretical physicists and original thinkers of the 20th century. He rebuilt the theory of quantum electrodynamics, and it was for this work that he won the Nobel Prize in 1965. In 1981, he gave Horizon a candid interview, talking about many things close to his heart.
Light always travels at a speed of 299,792,458 meters per second. But if you're in motion too, you're going to perceive it as traveling even faster -- which isn't possible! In this second installment of a three-part series on space-time, CERN scientists Andrew Pontzen and Tom Whyntie use a space-time diagram to analyze the sometimes confounding motion of light.
Just how small are atoms? And what's inside them? The answers turn out to be astounding, even for those who think they know. This fast-paced animation uses spectacular metaphors (imagine a blueberry the size of a football stadium!) to give a visceral sense of the building blocks that make our world.
