A Cosmology Inspired Unified Theory of Gravity and Electromagnetism: Classical and Quantum Aspects

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 ${\mathrm{\Gamma }}_i$ is curl-less.
