Evolutionary, statistical, and indirect indications are outlined to show that the supernova remnant Cas A does not have an empty interior, but contains a neutron star at its center, in close orbit around a normal star, and is illuminated by this binary system. The main arguments against an empty interior of Cas A are the following: (1) the existing finite scale, strong magnetic fields are difficult to explain by existing empty interior hypotheses because the dynamo involved in such hypotheses needs time to enlarge the interstellar magnetic field, and relativistic particles are difficult to produce by the ordered motion of a detonation wave; (2) if the majority of supernova explosions did not result in the birth of a neutron star, we might see more pulsars than have been violently born; (3) there is a trend both in late stellar evolution theory and in astration theory towards assigning an increasingly large probability to neutron star formation in supernova explosions.
