The best explanation I ever saw, for the speed of light, came from [PBS Spacetime](https://youtu.be/msVuCEs8Ydo).
The important thing is that the speed of light has nothing to do with light itself. The speed of light is the speed of causality. The speed of “cause and effect”. Light just moves at that speed because it has no mass to slow it down.
