Designated by the letter 'c.' In empty space it equals 299,790 km per second (186,282 miles per second). The speed of light has the same value independent of the relative velocity between source and observer, an experimental fact that makes sense only if relative motion changes the relationship betw...

Light travels at a speed of 186,282 miles per second in vacuum from the point of view of a nearby observer. Because of the effects of general relativity the speed of light near a massive object will appear slower to a distant observer, and this effect has been confirmed in experiments.The speed of light is the theoretical limit to the speed of any ...
