>>11095550>if someone asks "Why is the speed limit on the highway 55mph?" - "Because the sign says so!" or "25+30 = 55" or "Cuz miles are arbitrary!", aren't legitimate answers.That's because the mile is defined first, and only then is the numeric value of the highway speed limit set in terms of miles.
But for the speed of light, it's a universal constant that had a value even before humans existed, and in fact the definition of the metre is set in terms of c.
To make this more explicit: if you followed
>>11094882's suggestion to
>invent a new measure called OPfaggots such that perhaps 1 OPfaggot = 0.3182731 metersthen the speed of light would be ~940 million OPfaggots per second. In which case, when asked "Why is the speed of light 940 million OPfaggots per second, and not some other number like 300million?", referring to the definition of the OPfaggot is a legitimate answer.
Keep in mind that
>>11094179 asked
>Why not another number instead for example?Keyword being "number", not value, which indicates that the answer must be sensitive to the choice of units.
