The Black Hole Particle Accelerator as a Machine to make Baby Universes

TL;DR

The paper proposes that the mass inflation instability inside rotating black holes acts as an extremely powerful particle accelerator, potentially enabling the creation of baby universes, and explains the prevalence of supermassive black holes.

Contribution

It introduces the concept of black hole mass inflation as a natural particle accelerator capable of producing conditions for baby universe formation, linking black hole physics to cosmological reproduction.

Findings

Mass inflation leads to collision energies exceeding the Planck scale.

Black holes act as natural particle accelerators with reproductive potential.

Supermassive black holes are efficient at producing conditions for baby universe creation.

Abstract

General relativity predicts that the inner horizon of an astronomically realistic rotating black hole is subject to the mass inflation instability. The inflationary instability acts like a gravity-powered particle accelerator of extraordinary power, accelerating accreted streams of particles along the principal outgoing and ingoing null directions at the inner horizon to collision energies that would, if nothing intervened, typically exceed exponentially the Planck energy. The inflationary instability is fueled by ongoing accretion, and is occurring inevitably in essentially every black hole in our Universe. This extravagant machine, the Black Hole Particle Accelerator, has the hallmarks of a device to make baby universes. Since collisions are most numerous inside supermassive black holes, reproductive efficiency requires our Universe to make supermassive black holes efficiently, as is observed.
