Gravitational collapse of spherically symmetric stars in noncommutative general relativity

TL;DR

This paper explores the gravitational collapse of spherically symmetric stars within noncommutative general relativity, using deformation quantisation to model quantum effects on spacetime during collapse.

Contribution

It introduces a novel approach by applying deformation quantisation to model noncommutative spacetimes in gravitational collapse scenarios.

Findings

Noncommutative geometries can describe gravitational collapse.

Quantisation affects the classical collapse process.

New insights into quantum gravitational effects during collapse.

Abstract

Gravitational collapse of a class of spherically symmetric stars are investigated. We quantise the geometries describing the gravitational collapse by a deformation quantisation procedure. This gives rise to noncommutative spacetimes with gravitational collapse.
