I didn't think science was claiming the speed of light was constant.
I thought all those godless science guys (GSGs) were claiming it was
proportional to one over the square root of mu times epsilon. If the
speed of light were constant, then GPS wouldn't need two frequencies,
the ionosphere doesn't just bend - it delays. If time didn't vary,
GPS wouldn't need the frequencies of the satellite clocks adjusted for
the relativity effects of the satellite velocity or need the user
receiver relativity corrections that compensate for changes in the
observed satellite clock due to the velocity variations that come with
the permutations in the orbits.
