The Principle of Absolute Relativity
Sjaak Uitterdijk
The Special Relativity Theory (SRT) is based on two, in 1905 by Einstein proposed, presumptions: the first one, labelled by Einstein as the Principle of Relativity, 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. The article also shows how far away Einstein\textquoteright s theory is from such a solid solution.
