Space-time waves from a collapsing universe with a gravitational attractor

TL;DR

This paper investigates how a collapsing universe with increasing mass generates space-time waves due to back-reaction effects caused by geometrical deformation during exponential collapse.

Contribution

It introduces a model of space-time wave generation from a collapsing system with a growing mass, highlighting back-reaction effects as a novel mechanism.

Findings

Space-time waves are emitted during exponential collapse.

Back-reaction effects significantly influence wave generation.

Geometrical deformation drives the emission of space-time waves.

Abstract

We study a collapsing system attracted by a spherically symmetric gravitational source, with an increasing mass, that generates back-reaction effects that are the source of space-time waves. As an example, we consider an exponential collapse and the space-time waves emitted during this collapse due to the back-reaction effects, originated by geometrical deformation driven by the increment of the gravitational attracting mass during the collapse.
