CMBR anisotropy in the framework of cosmological extrapolation of MOND

TL;DR

This paper demonstrates that a modified gravity theory based on a critical acceleration can explain the CMBR anisotropy spectrum without dark matter, aligning with galactic and supernova data.

Contribution

It introduces a cosmological extrapolation of MOND that successfully models CMBR anisotropy, challenging the need for dark matter in cosmology.

Findings

Modified gravity fits CMBR multipole spectrum

Reproduces galactic rotation curves without dark matter

Provides testable predictions for cosmological observations

Abstract

A modified gravity involving a critical acceleration, as empirically established at galactic scales and successfully tested by data on supernovae of type Ia, can fit the measured multipole spectrum of anisotropy in the cosmic microwave background radiation, so that a dark sector of Universe is constructively mimicked as caused by the dynamics beyond the general relativity. Physical consequences, verifiable predictions and falsifiable issues are listed and discussed.
