The Parity Odd Universe, Dark Energy and QCD

TL;DR

This paper proposes that large-scale cosmological anomalies and alignments can be explained by a parity-odd local universe model, linking these phenomena to the nature of Dark Energy and its interactions with light.

Contribution

It introduces a novel framework connecting large-scale anomalies to a parity-odd universe, offering a unified explanation involving Dark Energy.

Findings

Large-scale anomalies may be correlated within a parity-odd universe model

Alignments in CMB and quasar polarization could stem from parity violation

A potential link between Dark Energy interactions and observed cosmological anomalies

Abstract

Cosmological observations on the largest scales exhibit a solid record of unexpected anomalies and alignments, apparently pointing towards a large scale violation of statistical isotropy. These include a variety of CMB measurements, as well as alignments of quasar polarisation vectors. In this paper we explore the possibility that several of the aforementioned large scale correlations are in fact not independent, and can be understood in a coherent way within the framework of a parity odd local Universe, and ultimately related to the nature of Dark Energy and its interactions with light.
