<p dir="ltr">This paper proposes a unifying principle — the Law of Natural Adjustment (LNA) — which asserts that all mass–energy systems adjust their configuration, distribution, or state in response to environmental conditions in a way that optimises continuity, stability, or least-action compliance.</p><p dir="ltr">We show that LNA underlies a wide range of known physical and chemical laws, from Hooke’s and Ohm’s Laws to Fourier’s Law and planetary motion.</p><p dir="ltr">In a major reinterpretation, we demonstrate that time dilation is not an illusion of perception but a physical slowdown of processes under relativistic motion. The Lorentz factor is reframed as a cost index — not for “time distortion,” but for mass-energy reconfiguration.</p><p dir="ltr">This work does not discard Special Relativity, but integrates it into a more grounded framework based on environmental response and adjustment. The equations remain; the interpretation evolves.</p><p dir="ltr">A full mathematical formulation is proposed, validated with classical derivations and relativistic data (including JEOL electron acceleration measurements).</p><p dir="ltr">We offer this paper as both a formal argument and a philosophical clarification — an invitation to reconsider what our physical laws are truly describing.</p>
