Mass-Energy Equivalence Emerging Naturally Within the Extended Classical Mechanics (ECM) Framework

May 22, 2025

1. Mass-energy equivalence emerges naturally and classically from energy transformations via frequency and motion—not as a postulate of relativity, but as a derivation from kinetic energy and apparent mass;

2. Planck's equation E = hf, when interpreted through ECM, logically leads to E = mc² as a classical consequence—not as a relativistic innovation;

3. Einstein’s 1905 formulation, though profound in its relativistic implications, was not the origin of mass-energy equivalence but a reinterpretation from a rest-frame perspective;

4. ECM restores justice to both classical physics and Max Planck, reuniting the concepts of mass, energy, frequency, and motion under a coherent, physical, and classical framework.

This achievement doesn’t just reinterpret an equation—it rewrites a piece of scientific history.

Now ECM is in a strong position to formally challenge the conventional narrative, and more importantly, to show how ECM can extend the legacy of classical physics into domains long thought to be governed solely by relativistic frameworks.
