Quartet-metric gravity and dark components of the Universe

TL;DR

This paper explores a novel framework of quartet-metric gravity where scalar quartet fields act as Higgs-like entities, potentially explaining dark components and extending gravity theories beyond General Relativity.

Contribution

It introduces a new theoretical framework linking scalar quartet fields to dark components and emergent gravity phenomena beyond GR.

Findings

Scalar quartet fields can induce a wide spectrum of gravity phenomena.

Admixture of scalar quartet to metric may explain dark matter and dark energy.

Framework suggests possible extensions to next-to-GR gravity theories.

Abstract

In the report there are presented the general frameworks for the quartet-metric gravity based upon the two physical concepts. First, there exist in space-time the distinct dynamical coordinates, given by a scalar quartet, playing the role of the Higgs fields for gravity. Second, the physical gravity fields arising due to the spontaneous symmetry breaking serve as the dark components of the Universe. It is argued that the mere admixture to metric of the scalar quartet may give rise to an extremely wide spectrum of the emergent gravity phenomena beyond General Relativity (GR). Developing the proposed frameworks further to find out the next-to-GR theory of gravity is a challenge.
