New Experiments: Faster Than Light
New experiments show that some things can travel faster than the speed of light.
But the Universe always manages to ensure that we can never use the effect for anything useful, like building a faster-than-light starship or travelling back in time.
It is a fundamental law of physics, a fact that is built into the architecture of the Universe and taught to every student, that nothing can travel faster than light which is roughly 300,000 km a second (186,000 miles).
Well not exactly. The Universe does have this speed limit but recent experiments would seem to suggest that in certain circumstan......
