Many body gravity and the bullet cluster

TL;DR

This paper introduces Many Body Gravity (MBG), a novel alternative gravity theory that explains galaxy dynamics and the Bullet Cluster's lensing effects without dark matter, by modeling thermal gradients as metric variations in a 5-D spacetime-temperature framework.

Contribution

The paper develops MBG as a new gravity theory that accounts for astrophysical phenomena traditionally attributed to dark matter, using a thermal gradient approach in higher-dimensional spacetime.

Findings

MBG explains galaxy rotation curves and RAR without dark matter.

MBG accounts for the Bullet Cluster's lensing effects.

MBG provides a unified framework for thermal and gravitational phenomena.

Abstract

Many body gravity (MBG) is an alternate theory of gravity, which has been able to explain the galaxy rotation curves, the radial acceleration relation (RAR) and the wide binary stars (WBS). The genesis of MBG is a novel theory, which models systems with thermal gradients, by recasting the variation in the temperature as a variation in the metric. Merging the above concept with Einstein's gravity, leads to the theory of thermal gravity in 5-D space-time-temperature. Thermal gravity when generalized for partially thermalized systems, results in the theory of many body gravity. The bullet cluster is supposed to be a smoking gun evidence for the presence of dark matter. However, this work demonstrates that the MBG theory can explain the weak gravitational lensing effect of the bullet cluster, without the need for yet undiscovered baryonic matter or dark matter.
