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

TL;DR

This paper challenges the view that time is equivalent to entropy, arguing that time's fundamental nature is rooted in quantum correlations and spacetime geometry, not entropy, and discusses the implications for the arrow of time.

Contribution

It offers a philosophical and physical critique of equating time with entropy, emphasizing the role of quantum vacuum correlations and spacetime structure in the persistence of temporal order.

Findings

Time's arrow is not solely due to entropy.

Quantum vacuum correlations underpin temporal structure.

Temporal order persists even in a maximally entropic universe.

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.
