Ok, I have a limited physics background. I have just enough knowledge
of relativity to be dangerous! A couple of questions from a simpleton
concerning the speed of light:
1. Why is the speed of light 300E6 m/s? Why isn't it a tenth that
speed? Why isn't it ten times that speed?
2. Since the speed of light is finite, what is there in a vacuum that
limits its speed? If a vacuum is truly empty as we classically think
of 'empty', shouldn't the speed of light in a vacuum be infinite? What
holds it back?

Just as the mass and tension establishes the propagation speed
on a musical instrument string, the mass and Coulomb force of
coupled electrons establishes the speed of light.
