LOL.Yesterday in bed I kept wondering why the speed of light is exact 299 792 458 m/sAnd ofc the answer turns out to be so very simple, I didn’t even think of itIt’s because the definition of a meter, in distance is based on the speed of light

@stux Hoping you'll elaborate for the slow kid (Me) :Everything else in metric is nice round base ten numbers, but I'm not seeing anything that looks like a commonsense "Oh, it's the speed of light divided by..." thing here:https://oeis.org/search?q=299792458

@stux @pre The speed of light ≈ 1 foot per nanosecond.
