Negative Energies and a Constantly Accelerating Flat Universe

TL;DR

This paper explores a modified General Relativity model with negative energies, showing it predicts a flat, constantly accelerating universe that aligns well with supernovae and CMB observations.

Contribution

It introduces a new set of conjugate metrics in GR that rehabilitate negative energy states without instability, and applies this to cosmology.

Findings

The model predicts a flat universe with constant acceleration.

Predictions align well with supernovae data.

Model agrees with CMB observations.

Abstract

It has been shown that in the context of General Relativity (GR) enriched with a new set of discrete symmetry reversal conjugate metrics, negative energy states can be rehabilitated while avoiding the well-known instability issues. We review here some cosmological implications of the model and confront them with the supernovae and CMB data. The predicted flat universe constantly accelerated expansion phase is found to be in rather good agreement with the most recent cosmological data.
