Contribution

It presents a novel broken symmetric unified framework linking gravity and electromagnetism with topological particle solutions, aligning with Milne cosmology and avoiding dark sector issues.

Findings

Milne cosmology aligns with most cosmological data

Dyons emerge as topological charges in the theory

The theory avoids dark sector problems

Abstract

Milne cosmology has recently been shown to be in broad agreement with most cosmological data while being free of the problematic notions of standard cosmology such as the dark sector. In this paper a broken symmetric unified theory of gravity and electromagnetism is introduced which has a Milne metric under a certain geometric condition. Strikingly, particles (dyons) emerge as topological charges in this theory provided the torsion vector $\Gamma_i$ is curl-less.
