Relativity and Cosmology


Einstein's and Galilei's Principle of Relativity

Authors: Sjaak Uitterdijk

The Special Relativity Theory (SRT) proposed by Einstein in 1905, is based on two presumptions: the first one, labelled by Einstein as the Principle of Relativity (PoR), and the second one defining the supposed property of the speed of light in vacuum. This article shows how close Einstein, as well as Lorentz, has been to a solid solution of the problems physicists encountered a century ago, observing electro-magnetic phenomena. It also shows that Einstein’s PoR is a fundamentally restricted version of the “now-a-days-PoR”.
