Going back to an earlier example of a sprinter running a 100 yard sprint on a long train car. Say the fastest this sprinter could ever run is 100 yards in 10 seconds. That is a his universal limit. The train is passing an observer standing at the train station going 100 yards per second at a constant velocity. The sprinter starts the race right as he passes the observer. In 10 seconds he has traveled 100 yards on the train car. The observer notes that the Sprinter covered 1100 yards in 10 seconds. Now we know that the sprinter can only cover 100 yards in 10 seconds. So giving that time is close enough to the same for both the sprinter and the observer the only relative difference is distance. So within one observer’s frame or World Line all laws of physics must hold true. This is not the case going from one to the other. As a traveler reaches new constant velocities distance must be re-calibrated to the inertial frames. So given that CERN is only measuring an observation occurring from one frame in a very short period of time Einstein’s truth that nothing can go faster than the speed of light holds true. The distance and time never had to be re-calibrated. All Physical Laws must hold true for an inertial frame.
