Elimination of DM on Rotational Curves Based on Field Interaction Theory (NIT5)

This paper presents a model for galaxy rotation curves based on the Nassimi Interaction Theory (NIT5)(https://doi.org/10.5281/zenodo.14997856), a novel framework that redefines spacetime as a dynamic scalar field, termed the timefield Θ. Grounded in established physics, NIT5 posits that Θ emerges from fundamental constants such as the speed of light c and Planck’s constant h, producing mass, gravity, and temporal structure without invoking dark matter. Here, this theory is applied to predict flat rotation curves using pseudo–isothermal profile for galaxies including UGC 05253, NGC 2403, UGC 09133, and NGC 6787, using a fixed parameter set validated through computational plotting. The approach leverages NIT5’s field equations to generate an effective mass contribution, ensuring repeatability and physical consistency across any galaxy dataset. Empirical results align with observed galactic dynamics, offering a field-based alternative to traditional dark matter hypotheses and demonstrating NIT5’s potential as a standalone explanation for gravitational phenomena. Python code for use is provided.
