# speed of light

The speed of light in vacuum, commonly denoted c, is a universal physical constant important in many areas of physics. Its exact value is 299792458 metres per second (approximately 300000 km/s (186000 mi/s)[Note 3]). It is exact because by international agreement a metre is defined as the length of the path travelled by light in

7/3/2018 · The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light. In miles per hour, light speed is, well, a lot: about 670,616,629 mph. If you could travel at the speed of light, you could go around the Earth 7.5 times in

Speed of light, speed at which light waves propagate through different materials. In a vacuum, the speed of light is 299,792,458 meters per second. The speed of light is considered a fundamental constant of nature. Its significance is far broader than its role in

Faster-than-light (also superluminal or FTL) communication and travel are the conjectural propagation of information or matter faster than the speed of light. The special theory of relativity implies that only particles with zero rest mass may travel at the speed of light. Tachyons, particles whose speed exceeds that of light, have
