(This would have gone to net.physics, but the local netnews person hasn't "created" the group locally yet...) By combining a couple of Maxwell's equations, one gets a wave equation describing electromagnetic wave propagation. As it turns out, this shows that the porpagation speed is equal to 1/sqrt(mu * epsilon), where mu and epsilon are the magnetice permeability and dielectric constant for the medium, respectively. In a vacuum, one obtains c = 1/sqrt( mu-0 * epsilon-0 ) Because of this relation, I suspect that if any of the constants c, mu-0, or epsilon-0 are a property of space itself, the other two would also be.
