Tests of Special Relativity

With the mass-energy \(m=E(v=0)/c^{2}\) relation, all pivotal properties of special relativity have been now derived and we consider the related status of SR tests. 1) There are direct tests exploring i) the speed of light in different context, ii) the time dilation, iii) the body contraction, and iv) mass-energy relation. 2) The Michelson-Morley experiment tests indirectly body-contraction and more generally the relativity principle and aether properties. 3) Another family of tests addresses the verification of the Lorentz coordinate transformation. 4) We describe the Doppler effect tests which test relativity per se. We close with a discussion of time and how it is different from space.
