Currently accepted explanations of the superluminal velocities reported by astronomers are characterized by a superunitary ratio of hypotheses to facts. This motivates a review of alternatives, beginning with doubts cast by investigations of Arp and Marmet on the distance scale of quasars and culminating in a reexamination of the foundations of kinematics. A simple analysis based on postulates of invariance of length and proper-time intervals leads to velocity nonreciprocity ? which explains the astronomical observations with logical economy. It also offers new perceptions concerning the well-known twin paradox.
