The Post-Anthropocentric Temperature Scale: Anchoring Thermodynamics Exclusively to Absolute Zero and the Triple Point of H2O

Key Points

The aim is to propose a universal temperature measurement system based on two invariant thermodynamic constants.
Review of existing temperature scales and their limitations
Introduction of the 'A' Scale as a proposed solution
Analysis of its practical implications for metrology
Highlights the limitations of existing temperature scales tied to Earth conditions
Introduces Absolute Zero and the Triple Point of H2O as foundational references
Suggests that the new scale enhances thermodynamic accuracy for future applications.

Abstract

For centuries, human thermodynamics has relied on localized temperature scales (Fahrenheit, Celsius) derived from Earth-specific atmospheric conditions and historical conveniences. While the Kelvin scale successfully anchored metrology to absolute zero, its increments remain bound to the localized Celsius system. As humanity transitions into a space-faring civilization, continued reliance on these historic scales represents metrological stagnation. This paper proposes the "A" Scale: a purely universal temperature measurement system anchored exclusively by two invariant thermodynamic constants—Absolute Zero (0) and the triple point of pure H2O(100)
