I think the solution to this question of why the speed of light is measured the same by all inertial observers can be answered by background independent theories such as LQG.

Thanks. This may turn out to be helpful.selfAdjoint said:The obvious way to replace c in the Planck computations with a strength parameter as you suggest would be to use alpha, the fine structure constant, aka the coupling constant of EM. Of course this brings in the charge on the electron.
Loop Quantum Gravity (LQG) theory is a theoretical framework that aims to unify Einstein's theory of general relativity and quantum mechanics. It proposes that space and time are not continuous, but rather made up of discrete chunks or "quanta".
LQG Theory predicts that the speed of light is not a constant, but rather varies depending on the energy density of the space it is traveling through. This means that the speed of light may be different in different regions of the universe.
According to LQG Theory, the speed of light is currently believed to be the maximum speed at which information can travel through space. However, this theory also suggests that the speed of light may have been much faster in the early universe, and has since slowed down due to the expansion of space.
Scientists can study the effects of LQG Theory on the speed of light through experiments and observations. For example, they can measure the speed of light in different regions of space and compare it to the predictions of LQG Theory. They can also study the behavior of light near massive objects, such as black holes, to see if it supports the predictions of LQG Theory.
If LQG Theory is proven to be correct, it would greatly impact our understanding of the universe and the fundamental laws of physics. It could potentially lead to a better understanding of gravity and the behavior of matter on a quantum level. It could also have implications for space travel and our ability to communicate across vast distances in the universe.
