A note and a new perspective on particle horizon problem

TL;DR

This paper reexamines the particle horizon problem, clarifies misconceptions, and proposes a new solution that does not rely on physics at the Planck scale.

Contribution

It offers a novel perspective on the particle horizon problem, providing an alternative solution independent of Planck-scale physics.

Findings

Clarification of misconceptions about the particle horizon problem

Introduction of a new solution independent of Planck time physics

Potential implications for cosmological models

Abstract

We cautiously reanalyze some easily confused notions on particle horizon problem in this paper and then we give a new answer to the particle horizon problem. This answer is independent of physics plunging into Planck time.
