Abstract
A causal anomaly for signals or particles traveling faster than the speed of light is described. The reinterpretation of "negative-energy particles traveling backwards in time" as positive-energy particles traveling forward in time fails to resolve the paradox. Uncertainties in velocities and times introduced by quantum-mechanical considerations also fail to resolve the paradox.Keywords
