End of a Dark Age?

TL;DR

This paper proposes that dark matter and dark energy phenomena can be explained by small geometric corrections to spacetime due to disordered locality, challenging the need for non-baryonic dark components.

Contribution

It introduces a novel geometric framework that accounts for dark matter and dark energy effects without invoking non-baryonic particles or a cosmological constant.

Findings

Fits galactic rotation curves without dark matter

Matches X-ray cluster mass profiles without modified gravity

Reproduces supernova data without dark energy

Abstract

We argue that dark matter and dark energy phenomena associated with galactic rotation curves, X-ray cluster mass profiles, and type Ia supernova data can be accounted for via small corrections to idealized general relativistic spacetime geometries due to disordered locality. Accordingly, we fit THINGS rotation curve data rivaling modified Newtonian dynamics, ROSAT/ASCA X-ray cluster mass profile data rivaling metric-skew-tensor gravity, and SCP Union2.1 SN Ia data rivaling $\Lambda$CDM without non-baryonic dark matter or a cosmological constant. In the case of dark matter, we geometrically modify proper mass interior to the Schwarzschild solution. In the case of dark energy, we modify proper distance in Einstein-deSitter cosmology. Therefore, the phenomena of dark matter and dark energy may be chimeras created by an errant belief that spacetime is a differentiable manifold rather than a disordered graph.
