About Speed of Light (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.
About Mach (Ma)
The Mach number expresses speed as a ratio to the local speed of sound, which varies with temperature and altitude. At sea level and 20 degrees C, Mach 1 is approximately 1,235 km/h. Fighter jets routinely exceed Mach 2, and the retired Concorde cruised at Mach 2.04.
