The "speed of light" is a function of the permeability and the permittivity of the medium that the "light" traverses.
If a medium is homogenous [ The same everywhere] and isotropic [The same in all directions] the "speed of light" in THAT medium will be constant.
If one makes the faulty ASSUMPTION that the volume integral of the product of permeability and permittivity
is CONSTANT for ALL unit spheres in the universe they are lead to believe that the "speed of light" is also a constant everywhere.
Of course, if one make this assumption, they will not be able to exploit the PHYSICS involved where the volume integral of the product of permeability times permittivity is not a constant, such as in material objects, and regions of microspace.
