The speed of light is a fundamental constant, approximately 299,792,458 meters per second. It's the same for all observers and hasn't changed measurably over billions of years. Nothing can travel ...

Einstein’s famous equation states that energy (E) equals mass (m) times the speed of light squared (c 2); the speed of light (c) is a universal physical constant exactly equal to 299,792,458 meters ...
