Sandokhan, that's a nice claim you got there. It would be a shame if someone were to look into it.
But those are not Maxwell's equations at all; on the contrary, they are the Heaviside-Lorentz equations:
Heaviside-Lorentz equations? Do you mean Heaviside-Lorentz units, which are a set of standards about how units are expressed in physics equations? Maxwell's equations in Heaviside-Lorentz units are still Maxwell's equations because they are the same exept they are written in a different equivelent form.
As for the "real" equations, I have searched and searched and I cannot find where you got your information. In all the sources you cited I did not find where you got the most important part of your argument on which everything else is built, which is that Maxwell's equations don't require the speed of light to be a constant. I don't even know what all te variables mean in those "real" equations so I can't do anything with them.
Your post also doesn't address the fact that special relativity and general relativity have been proven experimentally multiple times. One famous experient is one where an atomic clock was put on a plane and another perfectly synced one was left on the ground and when the plane flew around the world the clocks were offset by a tiny amount that matches perfectly with presictions made by relativity equations. This experiment was repeated multiple times with different clocks, different planes, and different flight paths all with simelar results.
There is another experiment where the speed of light was measured coming from the Sun at sunset and sunrise. The Sun rises to the east of you and sets to the west of you, so there is no question that it moves west relative to you no matter what model you use. The experiment found that the speed of light was the same in both instances. This experiment was repeated multiple times with simelar results. This experiment lead to the theory that light travels at light speed relative to the "aether", but that model failed to explain so much.
