70 91 v 2 1 4 Fe b 20 02 Faster-than-c signals , special relativity , and causality


Motivated by the recent attention on superluminal phenomena, we investigate the compatibility between faster-than-c propagation and the fundamental principles of relativity and causality. We first argue that special relativity can easily accommodate — indeed, does not exclude — faster-than-c signalling at the kinematical level. As far as causality is… (More)
