The Carmeli metric correctly describes spiral galaxy rotation curves

TL;DR

The paper demonstrates that Carmeli's 5D metric can accurately model spiral galaxy rotation curves and reproduce the Tully-Fisher relation without requiring dark matter, challenging conventional explanations of galactic dynamics.

Contribution

It shows that Carmeli's 5D space-time-velocity metric can explain galaxy rotation curves and the Tully-Fisher relation without dark matter.

Findings

Carmeli metric reproduces the Tully-Fisher relation

Galaxy rotation curves are described by the metric alone

Dark matter is not necessary in this model

Abstract

The metric by Carmeli accurately produces the Tully-Fisher type relation in spiral galaxies, a relation showing the fourth power of the rotation speed proportional to the mass of the galaxy. And therefore it is claimed that it is also no longer necessary to invoke dark matter to explain the anomalous dynamics in the arms of spiral galaxies. An analysis is presented here showing Carmeli?s 5 dimensional space-time-velocity metric can also indeed describe the rotation curves of spiral galaxies based on the properties of the metric alone.
