Black hole mass decreasing due to phantom energy accretion

TL;DR

This paper presents a solution for dark energy accretion onto black holes, demonstrating that phantom energy causes black hole masses to decrease and tend to zero as the universe approaches the Big Rip.

Contribution

It generalizes the Michel accretion solution to include dark energy, showing that phantom energy leads to black hole mass reduction.

Findings

Black hole mass decreases due to phantom energy accretion.

All black holes tend to zero mass in a phantom energy universe.

Mass loss accelerates as the universe approaches the Big Rip.

Abstract

Solution for a stationary spherically symmetric accretion of the relativistic perfect fluid with an equation of state $p(\rho)$ onto the Schwarzschild black hole is presented. This solution is a generalization of Michel solution and applicable to the problem of dark energy accretion. It is shown that accretion of phantom energy is accompanied with the gradual decrease of the black hole mass. Masses of all black holes tend to zero in the phantom energy universe approaching to the Big Rip.
