Your lack of physics knowledge is showing again. Precisely this experiment has already been done, between CERN and Gan Sasso, middle Italy, with high energy neutrinos. (so no tunnel needed) The atomic clocks at CERN and Gran Sasso were synchronised by refering to the GPS sats that were visible simultaneously from both places. Does your peculiar physics predict a measured speed of c for the highly relativistic neutrinos, and if not, what else? Jan
