faster-than-light introduction
Super light speed (faster-than-light, FTL or superluminality), which is greater than the speed of light traveling in a vacuum (299792458m / s) It will become a discussion topic, derived from the inference limit of the speed of light c in vacuum in local objects in the theory of relativity. ) Becomes the upper limit of the rate in many cases. Prior to this, Newtonian mechanics did not limit the speed of light.
