Unimodular bimode gravity, grand unification and the scalar-graviton dark matter

TL;DR

This paper integrates unimodular bimode gravity with grand unification, proposing a scalar-graviton dark matter model that explains galaxy rotation curves and predicts high-energy behavior modifications.

Contribution

It introduces a hyper unification framework merging systo-gravity with grand unification, explaining dark matter and galaxy rotation curves within a unified theory.

Findings

The local scale violation scale is about 10^15 GeV.

The scalar-graviton (systolon) emerges below the unification scale.

Modified high-energy behavior of the systolon is predicted at high temperatures.

Abstract

In prior article of the author, the unimodular bimode gravity/systo-gravity, with the scalar-graviton/systolon dark matter, was worked out. To compile with the anomalous rotation curves of galaxies the scale of the local scale violation in the theory was shown to be about 10^15 GeV. In this letter, to naturally incorporate such a scale the hyper unification framework, merging systo-gravity with grand unification through matter, is constructed. The systolon, as a free propagating compression mode in metric, emerges only below the unification scale, possessing at the same time a modified high-energy behavior to be manifested at the high temperatures.
