Speed of light in vacuum
Sobre Velocidade da Luz (c)
Exactly 299,792,458 meters per second in vacuum, the speed of light is a fundamental physical constant and the ultimate speed limit in the universe. Fiber optic signals travel at about 0.67c through glass, and GPS satellites must account for relativistic time dilation caused by their orbital speed relative to Earth's surface.
