A Cosmological Model without Singularity and Dark Matter

TL;DR

This paper proposes a cosmological model without singularities that includes symmetric s-matter and v-matter, explaining dark energy and multiple types of dark matter, and predicts the existence of dark galaxies and celestial bodies.

Contribution

It introduces a novel cosmological framework with symmetric matter types and predicts new dark matter components and dark celestial structures.

Findings

The model confirms big bang nucleosynthesis is unaffected by mirror matter.

Identifies three types of dark matter with specific density ratios.

Predicts the existence of dark galaxies and celestial bodies.

Abstract

According to the cosmological model without singularity, there are s-matter and v-matter which are symmetric and have oppose gravitational masses. In V-breaking s-matter is similar to dark energy to cause expansion of the universe with an acceleration now, and v-matter is composed of v-F-matter and v-W-matter which are symmetric and have the same gravitational masses and forms the world. The ratio of s-matter to v-matter is changeable. Based on the cosmological model, we confirm that big bang nucleosynthesis is not spoiled by that the average energy density of W-matter (mirror matter) is equal to that of F-matter (ordinary matter). According to the present model, there are three sorts of dark matter which are v-W-baryon matter (4/27), unknown v-F-matter (9.5/27) and v-W-matter (9.5/27). Given v-F-baryon matter (4/27) and v-W-baryon matter can cluster and respectively form the visible galaxies and dark galaxies. Unknown v-F-matter and v-W-matter cannot cluster to form any celestial body, loosely distribute in space, are equivalent to cold dark matter, and their compositions are unknown. The number in a bracket is the ratio of the density of a sort of matter to total density of v-matter. The decisive predict is that there are dark celestial bodies and dark galaxies. The energy of F-matter can transform into the energy of W-matter by such a process in which the reaction energy is high enough.
