Dark matter formation at Schwarz scales: primordial fog particles and WIMP superhalos

Original · EN

Dark matter appears in two forms as a consequence of the fluid mechanics of self-gravitational condensation. Condensation occurs primarily on non-acoustic nuclei rather than on the acoustic nuclei of the Jeans (1902) criterion, leading to a very different scenario for structure formation. Viscous forces at 10¹2 s (30,000 y) after the big bang permit decelerations of 10⁴7 kg protosupercluster plasma masses, and 10⁴2 kg protogalaxy masses at 10¹3 s (300,000 y). Then gas formed, and all the baryonic universe became a "primordial fog" of 10²3 kg particles at the viscous Schwarz scale: 100% dark matter. Some of these H-He objects have collected to form stars, but most persist as dark dwarfs in galaxy halos. They manifest themselves in quasar microlensing observations as "rogue planets", Schild (1996), "dark galaxies", Hawkins (1996), and as comets "brought out of cold storage", O'Dell and Handron (1996). Non-baryonic WIMP fluids are superviscous, with large viscous Schwarz scales, and condense slowly to form most of the dark matter of galaxy superclusterhalos and clusterhalos.
