VARIABLE SPEED OF LIGHT IN FRANCE

"Lightspeed variable say intellectuels français (...) The study, by Marcel Urban of France's University of Paris-Sud in Orsay, suggests that the energy fluctuations in vacuum could also affect the speed of light..."

Is the absolute frame really a nonsense? Toulouse 4-6 November 2013, Marcel URBAN: "comparing Einstein relativity with Lorentz-Fitzgerald theory: Lorentz-Fitzgerald postulates: 1- Absolute frame 2- Rod contraction 3- Clock retardation. Einstein postulates: 1- All inertial frames are equivalent 2- Speed of light invariant. (...) Conclusion: An absolute frame is not necessarily nonsense!"

Bravo, Marcel Urban ! You are on the wrong track of course (there is no "rod contraction" and "clock retardation") but at least you are challenging the constancy of the speed of light - an act which, in Divine Albert's world, is an act of heroism !
