    "abstract": "It is shown that time intervals Delta t\u0027 measured for photons moving with\nspeed v \u003e c can be of the same sign for all observers according to special\nrelativity, thereby avoiding any violation of Einstein causality. Previous\nassertions to the contrary have led to unnecessarily complicated\ninterpretations of experiments which indicate that single photons do travel\nwith faster-than-c speeds in regions of anomalous dispersion",
