Energy to mass ratio ,"c^2",would be an arbritrary constant if Space vacuum energy density was not homogenous?

Answer 1

No, no, no. It wouldn't *be* a constant if the permeability and permitivity of free space weren't homogenous. It would vary.

Have you gotten yourself signed up to actually take any Physics courses yet?

Answer 2

'c' is predicted by Maxwell's Equations. That fact was used by Einstein as a key point in formulating relativity.

While I have seen the derivation of 'c', I can't come anywhere close to understanding it. Although I am a former physics major at the University of Alberta, neither my physics background nor my mathematical background was up to snuff. It's not a simple process.

Answer 3

As always, your question does not make much sense. You are confused about basic concepts and terms, and you need to back up and start over with some basic physics and math. Ask your teacher.
