Wiktionary

  1. n. physics The speed of electromagnetic radiation in a perfect vacuum: exactly 299,792,458 metres per second by definition.

WordNet 3.0

  1. n. the speed at which light travels in a vacuum; the constancy and universality of the speed of light is recognized by defining it to be exactly 299,792,458 meters per second

Examples

  • “Obviously no information could be transmitted faster than the speed of light itself, but the act of defining the nature of one photon instanta­neously changed the nature of the other photon.”

    Prayers To Broken Stones

  • “By varying the number of cycles initiated per second, or millisecond for that matter, "and Breslaw beamed with paternal fondness for the abilities of his development," the f.tl. drive receives the power it requires to exceed the speed of light by any multiple required.”

    the ship who sang

  • “Changeover occurred and the ship slipped into that otherness of reality that was space-plus, allowing it not to ignore or defy the speed of light but to avoid it.”

    Running from the Deity

  • “There was Albert Michelson, who was to determine the speed of light with hitherto unknown precision; Jacques Loeb, the physiologist; Lloyd Morgan in sociology; there was a huge library, and a new journal of economics to edit.”

  • whichbe The speed of light in the vacuum of free space is an important physical constant usually denoted by the letter c. It is the speed of all electromagnetic radiation, including visible light, in free space. It is the speed of anything having zero rest mass. In SI units, the speed of light in a vacuum is exactly 299,792,458 metres per second (1,079,252,849 km/h). Experimental evidence has shown that the speed of light is independent of the motion of the source. It has also been confirmed experimentally that the two-way speed of light (for example from a source, to a mirror, and back again) is constant. Used to measure a light year. (Wikipedia) May 28, 2008
