Proposal for a New Light Speed Anisotropy Experiment Based on Time of Flight Method by Continuous Exchange of a Short Light Pulse Between Two Light Transponders

Authors: Henok Tadesse

A new light speed anisotropy experiment is proposed that is based on time of flight technique. Two light transceivers (transponders) A and B are fixed to each end of a rigid rod. A short light pulse initially emitted by transponder A is detected by transponder B, upon which B is triggered to emit a light pulse, which in turn is detected by A, upon which A is triggered to emit another light pulse which will be detected by B, and so on. A short light pulse is continuously exchanged between two light transponders. An electronic counter counts the pulses emitted. Changing the orientation of the rod with respect to Earth's absolute velocity direction will cause a variation of the number of pulses counted in a given period of time ( i.e. the frequency ). The unique feature of this experiment is that Earth's absolute velocity can be determined, theoretically, with any desired accuracy. The new 'transponder' technique may reveal many of the mysteries of the speed of light, including light speed anisotropy and the dependence of group velocity of light on mirror velocity, which would not be possible or difficult otherwise. Conventional methods involve a single pulse with spatially separated emitter and detector and clock synchronization. The new technique involves a free running, continuous exchange of a short light pulse, with the frequency determined by the round trip time of the light pulse itself. Change in the (group) velocity of light is detected as change in the frequency of the light pulses.
