Can Maxwell's equations deduce the principle of invariable speed of light? In Baidu Encyclopedia, it is said that the principle of invariable speed of light is obtained by solving Maxwell's equations. Is that right? If so, why did scientists at that time think that there was ether and that the speed of light was variable

In Baidu Encyclopedia, it is said that the principle of invariable speed of light is obtained by solving Maxwell's equations. Is that right?

Maxwell's equations show that the speed of light is only related to the dielectric constant and magnetic constant of matter, and has nothing to do with any reference object. Therefore, the principle of invariable speed of light means that the speed of light has nothing to do with the selection of reference object. When a train advances at the speed of light, the speed of any beam of light emitted from the ground he sees is the speed of light

Can Maxwell's equations deduce the principle of invariable speed of light?
I read Baidu Encyclopedia and said that the principle of invariable speed of light was obtained by the LIANLI Maxwell equations, which was confirmed by the Mai Mo experiment. Is this correct? Can Maxwell equations really deduce the principle of invariable speed of light? But some people say that it can't deduce the principle of invariable speed of light. I'm confused

A basic premise of Maxwell's equation is that the square root of the product of conductivity and permeability in vacuum is equal to the speed of light wave = the speed of light, and these two conductivities are detected as constants in experiments, so the square root of the product is also constant, so the speed is a constant
