A quantum black hole universe

TL;DR

This paper proposes a model where black hole growth from particle creation near the event horizon can explain the formation of supermassive galactic black holes and suggests a universe originating from a Planck-sized black hole undergoing eternal inflation.

Contribution

It introduces a power law for black hole growth based on particle creation limits, linking black hole evolution to cosmological phenomena and universe formation.

Findings

Black hole growth follows a specific power law.

Large galactic black holes can originate from smaller ones.

A black hole universe can reach critical density and undergo eternal inflation.

Abstract

Using the result obtained in a prevoius paper, in which I found an upper limit on the region of particle creation in the vicinity of the event horizon of a Schwarzschild black hole, and by assuming that all the created energy will be absorbed by the black hole, a natural power law for the growth of the event horizon is deduced. This result may explain the existence of galactic black holes with very large masses. Application of this result on cosmological scale shows that if we start with a Planck-sized black hole then the natural growth of such a black hole will produce one with a density equals the present critical density of the universe. Such a black hole universe will be in the state of eternal inflation.
