Remarks on the Fundamentals of Time oder die Zeitd\"ammerung

Abstract

This paper argues that the common identification of time with entropy is a category error. Entropy accounts for the arrow of time but not for time itself. Even in a maximally entropic universe the so called heat death temporal structure persists, grounded in the correlations of the quantum vacuum and the geometry of spacetime. The twilight of time is not its disappearance but its loss of directionality.
