Scientists at CERN, the famous Geneva-based physics lab, have just called into question one of the most hallowed equations in physics: E = MC2. Scientists, the AP explains, have clocked subatomic ...

The universe has a speed limit, and it's the speed of light. Nothing can travel faster than light — not even our best spacecraft — according to the laws of physics. So, what is the speed of light?
