Narrow Results

We argue that dark matter (DM)and dark energy phenomena associated with galactic rotation curves (RC’s), 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 the HI nearby galaxy survey (THINGS) RC data rivaling modified Newtonian dynamics, Roentgen Satellite/Advanced Satellite for Cosmology and Astrophysics (ROSAT/ASCA) X-ray cluster mass profile data rivaling metric-skew-tensor gravity, and SCP Union2.1 SN Ia data rivaling $\mathrm{\Lambda }$CDM without nonbaryonic DM or a cosmological constant. In the case of DM, we geometrically modify proper mass interior to the Schwarzschild solution. In the case of dark energy, we modify proper distance in Einstein–de Sitter cosmology. Therefore, the phenomena of DM and dark energy may be chimeras created by an errant belief that spacetime is a differentiable manifold rather than a disordered graph.

In Newtonian gravity, mass is an intrinsic property of matter, while in general relativity (GR), mass is a contextual property of matter, e.g. when two different GR spacetimes are adjoined. Herein, we explore the possibility that the astrophysical missing mass attributed to nonbaryonic dark matter (DM) actually obtains because we have been assuming the Newtonian intrinsic view of mass rather than the GR contextual view. Perhaps we should model astrophysical phenomena via combined GR spacetimes to better account for their complexity. Accordingly, we consider a GR ansatz in fitting galactic rotation curve data (THINGS), X-ray cluster mass profile data (ROSAT/ASCA), and CMB angular power spectrum data (Planck 2015) without DM. We find that our fits compare well with both modified gravity programs and DM programs.
