Now there is more evidence. If this new theory is correct it would be a milestone in our understanding of physics

OK, so if the speed of light is not a constant, then that means that the speed of other forms of electromagnetic radiation are also not constant. Thus, radar - both emitted and reflected - does not travel at a constant speed. Therefore, radar cannot really be calibrated against a known constant - because there is no known constant.
I think I just found a defense for my next speeding ticket...
