Role of Modified Chaplygin Gas as a Dark Energy Model in Collapsing Spherically Symmetric Cloud

TL;DR

This paper investigates the gravitational collapse of a spherical cloud containing dark matter and dark energy modeled as modified Chaplygin gas, revealing conditions under which black holes form, especially when dark energy dominates.

Contribution

It introduces the modified Chaplygin gas as a dark energy model in gravitational collapse, showing its unique effects on black hole formation.

Findings

Dark energy alone can form black holes.

Collapse favors black hole formation when dark energy dominates.

Results oppose traditional expectations.

Abstract

In this work, gravitational collapse of a spherical cloud, consists of both dark matter and dark energy in the form of modified Chaplygin gas is studied. It is found that dark energy alone in the form of modified Chaplygin gas forms black hole. Also when both components of the fluid are present then the collapse favors the formation of black hole in cases the dark energy dominates over dark matter. The conclusion is totally opposite to the usually known results.
