One weird theory could make anti-gravity and faster-than-light travel possible

So we've had neutrinos that traveled faster than light — or at least, that result hasn't been invalidated yet. But how soon can we get spaceships that can travel to other star systems without traveling at faster-than-light velocities? The answer might lie in a relatively little-known theory. » 11/03/11 7:00am 11/03/11 7:00am
