Abstract
The experimental evidence for electromagnetic signals propagating with superluminal group velocity is recalled. Transformations of space and time depending on a synchronization parameter, e1, indicate the existence of a privileged inertial system. The Lorentz transformations are obtained for a particular e1 different from zero. No standard experiment on relativity depends on e1, but if accelerations are considered only e1 = 0 remains possible. The causal paradox generated by superluminal signals in the theory of relativity does not exist in the theory with
e1 = 0. The irrelevance of superluminal signals for the Einstein, Podolsky and Rosen paradox is pointed out.
