Einstein, light, relativity, inconsistency
In 1905, A. Einstein published his paper “On the Electrodynamics of Moving Bodies”. In Section 1, the equation “ tB - tA = t’A - tB ” was provided; it describes a method for confirming the synchronization of two clocks by using a ray of light that makes a round trip between the clocks. Based on this method, Einstein established the Special Theory of Relativity (STR). In other words, his STR does not hold without the concept of light. The approach of employing a light ray is also useful for measuring distance; therefore, it is applied in many modern technological fields. However, there are other approaches, such as SONAR, that can be employed to achieve the same of purpose. In thought experiments aimed at confirming the above synchronization, another method that does not cause a time lag between the two clocks can be used. Using this method, STR becomes very simple and even non-scientists can easily confirm the synchronization of the clocks without any need for calculations. From the above, we can say that light is not the best means to study relativity.
