Checking the second law at cosmic scales

TL;DR

This paper argues that the second law of thermodynamics is valid at cosmic scales, supported by recent observational data on the universe's expansion history.

Contribution

It provides observational evidence confirming the second law's applicability at the largest observable scales in the universe.

Findings

Second law holds at cosmic scales

Recent Hubble data supports thermodynamic consistency

Aligns with previous theoretical studies

Abstract

Based on recent data about the history of the Hubble factor, it is argued that the second law of thermodynamics holds at the largest scales accessible to observation. This is consistent with previous studies of the same question.
