Behavior of Friedmann-Lemaitre-Robertson-Walker Singularities
L. Fern\'andez-Jambrina
TL;DR
This paper critically examines a recent regularization method for Big Bang singularities in FLRW spacetimes, highlighting its limited applicability to only certain types of singularities.
Contribution
The paper analyzes the scope of a proposed regularization procedure, demonstrating its limitations across different singularity types in FLRW models.
Findings
The regularization method applies only to specific Big Bang singularities.
Other singularity types remain unaffected by this procedure.
The applicability of regularization techniques varies with singularity characteristics.
Abstract
A regularization procedure has been recently suggested for regularizing Big Bang singularities in Friedmann-Lemaitre-Robertson-Walker (FLRW) spacetimes. We argue that this procedure is only appliable to one case of Big Bang singularities and does not affect other types of singularities.
