A phenomenological gamma-ray burst model postulating the injection of 1051-1053 ergs into a neutron star by Paczyński and by Goodman is closely reminiscent of what a relativistic version of a type I supernova might look like. Burning to tightly bound quark complexes (i.e., particles) could go explosively, just as the final burning of helium to iron disrupts a white darf in some models of type I supernovae. Particle theorists have for some years entertained the possibility that compressing nuclear matter may lead irreversibly to an exothermic formation of ``quark'' matter. From stellar evolution, we know that nuclear burning does not proceed directly to the known endpoint (iron) but is halted at various intermediate stages (e.g., at helium). Thus when the central densities of a neutron star begin to rise to that at which a transition to quark matter would be expected (10-20 times nuclear) owing to accretion or fusion with a companion neutron star, explosive burning may take place. Active galactic nuclei could be powered by such events and are therefore possible source regions. The particles themselves would be massive tightly bound bosons having zero spin, zero charge, and zero magnetic moment, hence could possible evidence themselves in the form of ``dark'' [=nonluminous] matter or ``WIMPs'' (weakly interacting massive particles). The relativistic shocks from such events should accelerate cosmic rays more efficiently than the usual supernova shocks.
