Asymptotic Suppression and the Non-Existence of Absolute Zero

Absolute zero temperature has never been attained experimentally and is formally excluded by the third law of thermodynamics, yet existing explanations rely primarily on statistical, operational, or microscopic arguments. In this work, we show that the non-existence of absolute zero follows directly from the suppression framework as a fundamental geometric constraint, independent of entropy-based reasoning or quantum assumptions.We formalize the asymptotic property of suppression: the suppression field may approach zero or unity but can never attain either limit. As a consequence, the rate of change of any physical system can be made arbitrarily small but never exactly zero. Absolute zero temperature, which would require complete cessation of physical change, is therefore fundamentally impossible rather than merely unattainable in practice.This asymptotic constraint provides a unified explanation for the persistent failure to reach zero temperature in cryogenic systems, the vanishing of heat capacity without complete freeze-out, and the absence of perfectly static or inert physical states. The same principle implies that even lowest-energy configurations retain non-vanishing physical change, with broader implications for thermodynamic and cosmological limits. Absolute zero is thus excluded by the same structural restriction that forbids perfectly frozen or singular end states within the suppression framework.
