Empirical Law for Galaxy Rotation Curves
Analysis
This paper proposes an alternative explanation for flat galaxy rotation curves, which are typically attributed to dark matter. Instead of dark matter, it introduces an empirical law where spacetime stores additional energy due to baryonic matter's distortion. The model successfully reproduces observed rotation curves using only baryonic mass profiles and a single parameter, suggesting a connection between dark matter and the baryonic gravitational potential. This challenges the standard dark matter paradigm and offers a new perspective on galaxy dynamics.
Key Takeaways
- •Proposes an alternative to dark matter for explaining flat galaxy rotation curves.
- •Introduces an empirical law where spacetime stores energy due to baryonic matter.

Reference
“The model reproduced quite well both the inner rise and outer flat regions of the observed rotation curves using the observed baryonic mass profiles only.”
