Did you know that the speed of light in a vaccum, c, has an exact value? It does. It is not subject to uncertainty or the accuracy of some empirical measurement. It is exactly 299,792.458 km/s.

This guy [link rottten] would have you believe that this stems from a seemingly arbitrary definition of what a meter is. I think he is wrong, and I'm going to proove it. The exact meter was based on the exact value of c, not vice versa. I think the exact value for c is based on the exact definitions of the permmitivity and permissivity of free space, and Maxwell's equations.

I find it odd that you can't find a good discussion of the exact speed of light anywhere on the web or in any of my physics texts. But I'm pretty sure I'm right.

Give me a few days, and I'll prove it. Really. I will, I think.
