The origin of nonluminous, nonbaryonic matter has been ascribed to a variety of hypothetical particles having masses many times that of the proton mass. Recent experimental searches for such particles seem to cast doubt upon their existence. In an alternative approach [1] to investigate the nature of nonluminous matter we showed that ultra-low mass bosons arise from the spontaneous symmetry breaking of a neutral scalar field coupled to gravity. Because of their very low mass, high density, and scalar symmetry, the particles constitute a sort of Weakly Interacting DeGenerate ETher (and thus have been termed WIDGETs). The critical condensation temperature of WIDGETs exceeds the temperature of the cosmic background radiation for most of the duration of the universe. If they exist, WIDGETs would therefore form a degenerate Bose-Einstein gas with Compton wavelength of astronomical extent, thereby providing a novel potential candidate for dark matter. [1] R. L.
