SRT Theorists, Can you handle a purely hypothetical question? Before we get to any subjects regarding the effect of expeimental results this question is designed and intyended as purely hypothetical. Let’s discuss the following gedanken. Two photons, l and r (<|>), are emitted simultaneously from the midpoint M of photon sensitive clocks L and R mounted at the front and rear of an inertial frame, Vf. The experiments can be conducted with Vf velocity v = 0, with respect to the embankment, or where Vf moves to the right with v > 0. The diagram defines the condition just as l, <, and r,>, are emitted: Code: L |_________________<|>_________________| R v -> l M r L and R are synchronized photon sensitive clocks that record the time of arrival of the photons l and r. tl and tr are travel times of the simultaneously emitted photons from M -> L and from M -> R. Hypothetical question: Is the measured tl < tr when v = 0 and when v > 0? Geistkiesel?
