Density perturbations in the gas of wormholes

TL;DR

This paper models dark matter as a gas of wormholes, demonstrating that their topological effects can mimic cold dark matter behavior and resolve galaxy cusp issues.

Contribution

It introduces a kinetic and hydrodynamic framework for wormhole gas, showing their large-scale effects mimic dark matter and improve galaxy core profiles.

Findings

Wormholes behave like heavy particles at large scales.

They reproduce features of CDM models.

They help resolve galaxy cusp problems.

Abstract

The observed dark matter phenomenon is attributed to the presence of a gas of wormholes. We show that due to topological polarization effects the background density of baryons generates non-vanishing values for wormhole rest masses. We infer basic formulas for the scattering section between baryons and wormholes and equations of motion. Such equations are then used for the kinetic and hydrodynamic description of the gas of wormholes. In the Newtonian approximation we consider the behavior of density perturbations and show that at very large distances wormholes behave exactly like heavy non-baryon particles, thus reproducing all features of CDM models. At smaller scales (at galaxies) wormholes strongly interact with baryons and cure the problem of cusps. We also show that collisions of wormholes and baryons lead to some additional damping of the Jeans instability in baryons.
