What level of math do you need to understand how Maxwell’s equations produce c?

So, does the permeability and permittivity of free space change as you speed up. I guess not because you will always measure c to be 3x10^8m/s. But your clock does run slower as you speed up so something must be going on.

Magnanimously insightful. I believe nothing is constant and once quantified, or as close to measuring as possible, we will make discoveries parallel to works of fiction. We are nothing and everything, and the source is inside all. The God molecule, philosopher’s stone, has many labels and is pursued by all.

How does light behave in an expansion universe

At least a C average would be my guess. oops dad joke.
