A Brief Account of the Concepts of Time in the Pre-Relativistic Electrodynamics and STR

Abstract

In this article, we examine the concepts of time such as classical time, local time, retarded time/advanced time and proper time prevalent in the prerelativistic period and the relativistic concepts of time expounded in Einstein’s STR. It is shown that the concept of retarded time/advanced time leads to the proof of Lorentz Transformation whereas the STR leads to a non-linear transformation in which y ≠ yꞌ and z ≠ zꞌ . From the analysis it follows that there is no new concept of time in STR, which contains a faulty use of retarded/advanced time.
