A few questions for anyone kind enough to reply and help me understanding this matter:
1. Since electromagnetic waves in vacuum have a maximum speed is this speed limited by the permittivity and permeability of the vacuum?
2. Or is it related to the density of the vacuum as it is for waves traveling through water and air?
3. If so, does permittivity and permeability creates this apparent density?
3. If so, is the vacuum of space even? Throughout the universe? or does it fluctuate for any reasons?
4. And if this density fluctuates, is it possible that light in vacuum could go faster or slower than its presently recorded speed? in some part of the universe?
Thanks you
