Dark Matter as Screened Ordinary Matter

TL;DR

This paper proposes a model where dark matter consists mainly of ordinary matter in the form of highly compressed vacuum pearls, supported by phenomenological evidence including X-ray observations and scattering data.

Contribution

It introduces a novel dark matter model with dominant ordinary matter content and provides phenomenological evidence supporting this hypothesis.

Findings

Support for dark matter mainly composed of ordinary matter in the model

Abstract

We look at our since long studied model for dark matter as being pearls of a speculated new vacuum containing highly compressed ordinary matter, with so much ordinary in it that the content of ordinary matter in the dark matter pearls dominate. Most dark matter models have the dark matter consisting mainly of new-physics-matter such as WIMPs being supersymmetric partners of possibly known particles or, as in Maxim Khlopovs model, a doubly negatively charged new-physics-particle with a helium nucleus attached. But usually the new-physics matter makes up weight-wise the major content. It is only in our model that the ordinary matter content in the dark matter dominates. We here expose some weak phenomenological evidence that, in truth, dark matter should be of the type with a dominant component of ordinary matter (weight-wise), thus favoring as the typical example our previously so much studied vacuum type 2 model. The main such evidence is that we manage a fit to data in which the 3.5 keV X-rays, presumed to result from dark matter, come both from collisions of dark matter with dark matter and from dark matter with ordinary matter! Both mechanisms are of so similar an order of magnitude that they are both seen, indicating that their similarity is due to a significant similarity between dark with ordinary matter. The fact that the amounts of ordinary and dark matter only deviate by a factor 6 points in the same direction. Using the information obtained from this fitting, we develop our speculation that the main content weight-wise of dark matter is ordinary matter to the very DAMA experiment. Actually we found three spots on the sky in which we fit the observed production of 3.5 keV X-rays with ordinary plus dark scattering.
