    "abstract": "The paper elucidates the physical basis of experimental results on\nsuperluminal signal velocity. It will be made plausible that superluminal\nsignals do not violate the principle of causality but they can shorten the\nluminal vacuum time span between cause and effect. This amazing behaviour is\nbased on the property that any physical signal has a finite duration.",
