Does not matter. The speed of light in medium is also always constant. Speed on light in water is always the same, in Helium gas is always the same and so on. The speed of light IS constant, it only has different speeds in mediums.
Wrong, light will travel slower in 100atm of air at room temperature than it will in 0.2 atm of air at room temp
Yeah? You're talking about two different kinds of medium, the same point still stands. The speed of light IS constant. The only thing that changes is the medium. You can't slow down the speed of light neither can you increase it. People who say they have slowed down the speed of light have only passed the light through a medium where the speed of light is really slow. Nothing groundbreaking stuff.
The quantum theory of atoms tells us that frequencies and wavelengths depend chiefly on the values of Planck's constant, the electronic charge, and the masses of the electron and nucleons, as well as on the speed of light.
By eliminating the dimensions of units from the parameters we can derive a few dimensionless quantities, such as the fine structure constant and the electron to proton mass ratio. These values are independent of the definition of the units, so it makes much more sense to ask whether these values change.
If they did change, it would not just be the speed of light which was affected. The whole of chemistry is dependent on their values, and significant changes would alter the chemical and mechanical properties of all substances.
Furthermore, the speed of light itself would change by different amounts according to which definition of units you used. In that case, it would make more sense to attribute the changes to variations in the charge on the electron or the particle masses than to changes in the speed of light.
Seeing as these contants, are infact constants and have not changed, then the speed of light is a constant.
Tell that to a theoretical event horizon.
