Peeling or not peeling -- is that the question ?

TL;DR

This paper reevaluates fundamental concepts in general relativity related to isolated systems and their asymptotic properties, discussing key results and open questions to deepen understanding of gravitational systems.

Contribution

It offers a new perspective on the concepts of isolated systems, asymptotic flatness, and simplicity, and discusses related results and open questions in the field.

Findings

Reconsideration of isolated self-gravitating systems

Discussion of asymptotic flatness and simplicity

Identification of basic open questions in the field

Abstract

The concepts of isolated self-gravitating system, asymptotic flatness and asymptotic simplicity are reconsidered, various related results are discussed and put into perspective, basic open questions are posed.
