Astrophysics and Dark Matter Theory

Abstract

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.

Accelerated Expansion of Space, Dark Matter, Dark Energy and Big Bang Processes

“…Their average kinetic energy would be 3 2 kT w kT mc = . These concepts are confirmed by astrophysical observations [7], which proved that the cosmic DM gas is cold. We mentioned in the introduction that the CDM Λ implies that 1 w = − , but DM particles interact with one another.…”

“…Moreover, it is sufficient that 0 a ≠ , to justify the Standard Model and to complete it in regard to DM particles [5] [6]. Predicted properties of the cosmic DM gas are confirmed by astrophysical observations [7]. Here, we examine other consequences, especially for the accelerated expansion of space and Big Bang processes.…”

“…Thermal agitation leads to pressure effects. They are important for the constitutions of DM atmospheres [7], but nearly negligible for the accelerated expansion of space. By measuring Λ, we could determine the average mass-energy density ρ.…”

From Space-Time Quantization to Dark Matter

“…Because of their mass, DM particles are also subjected to gravitational forces. This accounts for many astrophysical observations [13].…”

“…Astrophysical evidence indicates also that interactions between cosmic DM and baryonic matter are negligible and so far, even the most sensitive DM detector did not yield any evidence of interactions between DM particles and nucleons [22]. However, we will show that DM particles can interact with electrons [13].…”
