How 1 meter is defined
WebThe speed of light is constant. It is the same everywhere, and is the top speed: a universal speed limit. The way we measure distances now depends on this speed: the speed of light has been defined as 299,792,458 metre inverse second since 1983. So a metre is now how far light travels in 1 299,792,458 second.. In more easily visualisable terms, one foot … WebAnswer (1 of 5): If you mean the distance between two points in four dimensional spacetime the answer is almost the length light can travel within one second in vacuum, c = 299,792,458 m / s, so s = 299,792,458 m. If you stay almost in place (within the 3 space dimensions) you still falling throu...
