[Discussing special relativity, one user argues that the speed of light is constant, because otherwise the light-year would not be a consistently defined unit of distance.]
Empirical data suggest that the speed of light has changed over time, and as recently as 1/6th of the universe's lifetime.
You comments, like "distances were measured in ... light-years, and that only makes sense if the speed is constant," is a political statement, not a scientific one. Likewise for stating that "finding a variable c would now violate so much physics ...." Is this what university science has become - ignoring the data to preserve the reputation of some current and past professors?
