Gravity coupling from micro-black holes

TL;DR

This paper explores the possibility that quantum gravity effects could manifest at GUT energy scales through semi-classical analysis of micro-black holes, extending beyond traditional Planck-scale considerations.

Contribution

It introduces a framework for quantum gravity effects at GUT energies using semi-classical Hawking evaporation of micro-black holes within 4-dimensional gravity.

Findings

Quantum gravity effects may occur near GUT energies.

Micro-black hole evaporation can provide insights into quantum gravity.

Extends semi-classical analysis to higher energy regimes.

Abstract

Recently much work has been done in lowering the Planck threshold of quantum gravitational effects (sub-millimeter dimension(s), Horava-Witten fifth dimension, strings or branes low energy effects, etc.). Working in the framework of 4-dim gravity, with semi-classical considerations based on Hawking evaporation of planckian micro-black holes, I shall show here as quantum gravity effects could occur also near GUT energies.
