A Physical Source of Dark Energy and Dark Matter

TL;DR

This paper proposes a physical mechanism generating three energy components that unify dark energy and dark matter, fitting supernova data and suggesting a scalar field interpretation within spacetime.

Contribution

It introduces a novel physical model producing dark energy and dark matter components from a common origin, fitting observational data.

Findings

Model fits supernovae Union2 data as well as LambdaCDM.

Proposes a scalar field in spacetime as the source of dark components.

Suggests a unified physical origin for dark energy and dark matter.

Abstract

A physical mechanism that produces three energy components is proposed as the common origin of dark energy and dark matter. The first two have equations of state W ~ 0 and act like dark matter, while the last has W ~ -1 at low redshifts making it a candidate for dark energy. These are used to model the supernovae Union2 data resulting in a curve fitting identical to the LAMBDACDM model. This model opens new avenues for Cosmology research and implies a re-interpretation of the dark components as a scalar field stored in the metric of spacetime.
