<b>Neutron Stars in the MEG Universe: Stability, Collapse, and Exotic Compact Objects</b>

This paper explores the stability conditions and collapse mechanisms of neutron stars within the Mass-Energy Gravity (MEG) framework, which replaces spacetime curvature with energy-density gradients (EDGs). By deriving stability thresholds using energy redistribution constraints, we identify a fundamental limit, C_{\text{limit}}, beyond which neutron stars cannot redistribute energy fast enough to maintain equilibrium. This threshold naturally distinguishes stable neutron stars, hypermassive neutron stars (HMNS), and black holes without requiring exotic forces or dark matter.The study compares MEG predictions with observational data from LIGO/Virgo gravitational wave detections, pulsar mass-radius constraints (NICER), and black hole transition candidates (GW190814, PSR J0952−0607). The results confirm that MEG successfully predicts neutron star behavior and gravitational collapse using pure energy-density physics, challenging traditional spacetime-based interpretations.The findings suggest a testable energy redistribution threshold that could be validated through future gravitational wave observations and neutron star merger studies.
