Comments on The Experimental Proofs of Relativistic Length Contraction and Time Dilation by O. D. Jefimenko

Abstract

The subject of relativistic length contraction and relativistic time dilation appears very early in textbooks as well as in various forms in papers dedicated to teaching relativity. In his paper, O. D. Jefimenko considers “questionable” the experimental confirmations of these relativistic phenomena and offers an alternative explanation based on electromagnetic retardation. In the following short note, we will deconstruct Jefimenko’s proofs, and we will show their limitations.
