Opposite Thermodynamic Arrows of Time

TL;DR

This paper presents a model where two weakly coupled systems maintain opposite thermodynamic arrows of time, exploring implications for astrophysics and dark matter.

Contribution

It introduces a novel model of systems with opposite thermodynamic arrows of time and discusses their potential astrophysical significance.

Findings

Opposite-arrow systems can coexist with weak coupling.

Such systems could exist at stellar distances.

A possible link to dark matter is proposed.

Abstract

A model in which two weakly coupled systems maintain opposite running thermodynamic arrows of time is exhibited. Each experiences its own retarded electromagnetic interaction and can be seen by the other. The possibility of opposite-arrow systems at stellar distances is explored and a relation to dark matter suggested.
