A Symmetric Ring Galaxy Model Explains the Rotation Curve of Galaxies

Abstract

This paper proposes a symmetric ring galaxy (SRG) model based on the general structure of galaxies. Based on this model, we have obtained results that are consistent with the actual observation results of the galaxy rotation curve, thus solving the problem of inconsistency between the observation results of the galaxy rotation curve and the expected results, which has long plagued the astronomical community. This article also analyzes the root causes of the problem of galaxy rotation curves, and finds that the main reason is that people use unrealistic galaxy models and incorrect calculation methods. Therefore, the dark matter hypothesis and gravitational correction theory that explain the problem of galaxy rotation curves have lost their theoretical basis, and the correctness of these theories undoubtedly faces serious challenges and profound doubts.
