HYPER, Thanks for providing that interesting info which explains the "HOW TO" ... but my 'concern" is not "HOW TO" ... but rather "WHY WHO".
Why 186,282 (formerly merely 186,000) and not 200,000 or 300,000, or 400,282?
And WHO or WHAT precisely sets the speed of light at 186,282?
I'll read the info you provided to see if it offers a precise answer, but I bet it won't!
