Physics Students Scrutinize Planetary Stability In Super Mario Galaxy

The world's most famous plumber ventured into space with the release of Super Mario Galaxy. The 3D game used a physics system to endow celestial objects with their own gravity so our hero could circumnavigate tiny worlds without falling off. But to maintain surface gravity, how dense would these planets have to be? » 11/25/14 9:40am Yesterday 9:40am

What West Point Cadets Learned By Studying A Classic Scifi Novel

When Chris Moseley, an instructor at the U.S. Military Academy at West Point, decided to teach a "special topics" course on general relativity, he opted for an unusual supplementary textbook: Larry Niven's 1973 novel Protector, which vividly depicts a battle between spaceships moving at relativistic speeds. » 11/12/14 7:30am 11/12/14 7:30am

Freakishly Compact Particle Accelerators Could Revolutionize Physics

Experiments at the SLAC National Accelerator Laboratory in the U.S. have taken us a step forward in developing a technology that could significantly reduce the size of particle accelerators and allow scientists to accelerate particles more rapidly than conventional accelerators at a much smaller size. » 11/06/14 2:20pm 11/06/14 2:20pm

How Eddie Redmayne Captured the Charisma of Stephen Hawking

Eddie Redmayne pulls off a tremendous feat in The Theory of Everything, playing Stephen Hawking from the early 1960s to the late 1980s. Not surprisingly, he's already getting a lot of Oscar buzz. We sat down with Redmayne for an exclusive interview and he told us what it was like to meet the real Hawking. » 11/06/14 1:00pm 11/06/14 1:00pm

Yes, Time Travel Is Possible; Here's How

Time travel's been one of man's wildest fantasies for centuries. It's long been a popular trend in movies and fiction, inspiring everything from Charles Dickens' A Christmas Carol to H.G. Wells' The Time Machine to the Charlton Heston shrine that is The Planet of the Apes. And with the opening of Interstellar » 11/05/14 6:28pm 11/05/14 6:28pm

A Clock So Precise That It Detects Tiny Shifts In The Flow Of Time

In a basement lab at the University of Colorado Boulder, researchers have built the world's most accurate atomic clock — it can keep perfect time for 5 billion years. But the clock is so precise that it's run into a problem. Time doesn't move at the same rate everywhere in the cosmos, or even on the surface of Earth. » 11/05/14 7:40am 11/05/14 7:40am
