    The speed of light = 299 792 458 m / s.

    Right for metric users.
    186,000 miles per second for us US

    I know it is faster then the speed of sound

    The approx. of 300,000 km/s or 186,000 miles/second are both quite close (exact speed is pointless until you need it for math at that level).


    This is the fastest speed attainable in Eintsein's known universe - often called the "cosmic speed-limit," etc...


    It's a truly mindblowing speed, and no particle of matter can travel at it's exact speed - but reaching 99.9999%  of it is totally fine with our understanding of physics.

    Dont know I am always in the "Dark"
