Astrophysics and Dark Matter Theory

Space-Time Quantization implies that the cosmic dark matter gas is subjected to pressure effects. We prove this by accounting for the mass-density distribution of dark matter in galactic halos. It can be directly deduced from observed rotation curves and coincides with theoretical predictions for dark matter atmospheres in hydrostatic equilibrium. Through embedding, the pressure of the cosmic dark matter gas prevents also the gravitational collapse of the Oort cloud, globular star clusters and cosmic filaments. The Sun has only a very small dark matter atmosphere, but observations confirm that dark matter is orbiting around the Sun. Other facts are explained by planetary dark matter disks. Space-Time quantization accounts also for dark matter-electron interaction, which allowed already for direct detection of galactic dark matter particles.
