<b>The Mass-Energy Gravity Model: A Fundamental Alternative to Dark Matter</b>

This paper introduces the <b>Mass-Energy Gravity (MEG) framework</b>, a paradigm-shifting alternative to ΛCDM that eliminates the need for <b>dark matter</b> in explaining galaxy dynamics and gravitational lensing. MEG is built on a reinterpretation of the <b>speed of light (</b><b>c</b><b>)</b>—not just as a velocity limit, but as a <b>fundamental constraint on energy-density concentration</b>, leading to the derivation of a <b>maximum energy-density limit called the Unified Limit (</b><b>U</b><b>)</b>.<br>By replacing <b>spacetime curvature with energy-density gradients (EDGs)</b>, MEG explains gravitational effects as emergent from mass-energy redistribution rather than intrinsic warping of spacetime. This paper rigorously derives three key relativistic effects—<b>Mercury’s precession, frame-dragging, and gravitational time dilation</b>—from first principles, confirming that all independently predict the same value of U.Using this foundation, MEG successfully reproduces <b>flat galaxy rotation curves</b> and <b>gravitational lensing effects</b>, including Einstein Rings and the Bullet Cluster, without invoking dark matter halos. Additionally, U is found to <b>match black hole density</b> and <b>describe neutron star stability</b>, providing a natural resolution to singularity formation in General Relativity.This work demonstrates that MEG offers a fully self-consistent, observationally validated alternative to ΛCDM, providing a new perspective on gravity and large-scale cosmic structure without requiring dark matter.<br><br><i>For inquiries, please contact me at:</i> <b>[email protected]</b><br>
