Son Goku,
Thanks for your reply. I find your answer to be insightful and I see how you're thinking about my question. But my intended question requires a bit of a different answer; I think cavediver sees that, and has addressed my question as I intended it to be read. Let me try and restate it.
Son Goku writes:
We humans simply invented a measurement of time called the second and a measurement of space called the meter.
The only reason there is a "speed of light" is because the temporal measurement is so mismatched from the spatial one.
That is the explanation of the magnitude, our disproportionate measurement system.
Your argument is that we could have defined different units, in order to get "the speed of light" to be any number we want, and of course that's right.
But if measure in meters and seconds, we always get the speed of light to be 3x10^8m/s. This has to do with the relationship between space and time. My question is, why do we find THIS relationship between space and time? What is it that makes us measure the speed of light to be 3x10^8m/s, and not 1m/s. Because, although it's possible to measure the speed of light as 1(length unit "A")/(time unit "B"), it's impossible (theoretically) or never-been-done (experimentally) to measure the speed of light, in m/s, as anything but 3x10^8m/s.
Something has fixed the relationship between space and time to be very specific, and I want to know what is fixing it that way.
Bah, that didn't help at all I think. Well, if not, then I'll drop it; I'm satisfied with cavediver's previous answer (thanks for that).
Ben
