Einstein's theory of special relativity sets of the speed of light, , miles per second ( million meters per second). The speed of light in a vacuum is , miles per second (, kilometers per second), and in theory nothing can travel faster than light.
The speed of light is actually DEFINED to be m/s. Now even light can't travel faster than 'c', because if it does, it will also gain relativistic mass.
The speed of light in vacuum, commonly denoted c, is a universal physical constant important .. In neither case does any matter, energy, or information travel faster than light. .. has the effect of fixing the speed of light to an exact value in astronomical units per second (via the exact speed of light in metres per second).
Light travels in a vacuum at , miles per second or ,, meters/ second. For simplicity, it is often said that these numbers are.
