Hurtling across the galaxy in a starship powered by anti-matter isn't some sci fi writer's impossible dream, as Dr Michio Kaku proves when he reveals his blueprints for a spacecraft that can journey to the stars. Alpha Centaurii is nearer than you think.
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.

We feel it every moment of our lives but for physicists, gravity is the longest running unsolved mystery of the universe. Why do all objects that have mass pull on one another? Cutting-edge theories are proposing unexpected answers.
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.
On May 16, 2011, Professor of Physics Emeritus Walter Lewin returned to MIT lecture hall 26-100 for a physics talk and book signing, complete with some of his most famous physics demonstrations to celebrate the publication of his new book For The Love Of Physics: From the End of the Rainbow to the Edge of Time - A Journey Through the Wonders of Physics, written with Warren Goldstein.

The classical physics that we encounter in our everyday, macroscopic world is very different from the quantum physics that governs systems on a much smaller scale (like atoms).
