| No Bill! We are not shaking hands simultaneously because, unlike you, I am not in an inertial frame of reference. |

| The boxcar moves from left to right and two lightning bolts strike locations A (rear) and B (front). At the moment the bolts strike, two observers (passenger P and stationary observer O) are equidistant from A and B. According to Einstein, light from the event at B should arrive to P sooner than from A because the passenger is traveling in the direction of B. The observer standing on the platform should measure both events as happening simulta- neously. Hence, Al says that simultaneity is a function of measurement, location, and the speed of light. |

| We redesign Einstein’s gedanken experiment by removing all observers. Instead, we place a gullible relativist in an electric chair smack in the middle of the platform and equidistant from points A and B. If lightning strikes A and B at the same time, the bolts electrocute the relativist. We are done! Otherwise, only one bolt reaches the chair, toasts his P-brain, and sears his tongue. Irrespective of the results, we won’t need his testimony at trial. Relativity’s simultaneity argument relies on measurements and malleable definitions, both of which are subjective. If ever an experiment invokes testimony, we are talking either Mathematics or religion, not Physics. |
