The Dark Side of Gravity

TL;DR

This paper proposes an alternative, non-geometrical theory of gravity where the true metric is Minkowskian, challenging the traditional geometric interpretation of spacetime in General Relativity and addressing issues with Lorentz symmetries.

Contribution

It introduces a flat, Minkowskian framework for gravity that reinterprets the gravitational field without relying on spacetime curvature, emphasizing discrete symmetries and their representations.

Findings

Rehabilitation of global discrete spacetime symmetries

Reinterpretation of the gravitational tensor as a non-metric field

Addressing negative energy and tachyonic representations

Abstract

Adopting a non geometrical point of view, we are led to an alternative theory of the order two and symetric gravitational tensor field of GR. The field is no more interpreted as the metric of our space-time. The true metric is globally Minkowskian and describes a flat manifold, a context which justifies a genuine rehabilitation of the global discrete space-time symetries involved in the structure of the Lorentz group along with their 'problematic' representations: the negative energy and tachyonic ones.
