"The dark world might even be as diverse and interesting as the visible world," Katz and his colleagues wrote May 23 in the journal Physical Review Letters. The interactions between dark protons and dark electrons could make them lose energy over time. As such, they might slow down enough to clump into flat disks around galaxies, just like regular matter does. In contrast, most dark matter apparently forms roughly spherical haloes around galaxies, stars and planets. This concept means galaxies would have two disks, one made of regular atoms and one of dark atoms, which is why the investigators call their idea the double-disk dark matter model. space/21508-dark-matter-atoms-disks.html
