Quantum Black Holes As Elementary Particles

TL;DR

This paper explores the hypothesis that quantum black holes could be elementary particles, potentially explaining cosmic ray limits and dark matter, by constructing various fundamental quantum black hole models.

Contribution

It introduces a framework for modeling quantum black holes as elementary particles with different spins and charges, linking general relativity to particle physics.

Findings

Quantum black holes could resolve cosmic ray energy paradoxes.

They may serve as dark matter candidates.

Models include spin-0, spin-1/2, spin-1, and Planck-charge black holes.

Abstract

Are black holes elementary particles? Are they fermions or bosons? We investigate the remarkable possibility that quantum black holes are the smallest and heaviest elementary particles. We are able to construct various fundamental quantum black holes: the spin-0, spin 1/2, spin-1, and the Planck-charge cases, using the results in general relativity. Quantum black holes in the neighborhood of the Galaxy could resolve the paradox posed by the Greisen-Zatsepin-Kuzmin limit on the energy of cosmic rays from distant sources. They could also play a role as dark matter in cosmology.
