Generalized Uncertainty Principle in Quantum Gravity from Micro-Black Hole Gedanken Experiment

arXiv:hep-th/9904025 · doi:10.1016/S0370-2693(99)00167-7

Abstract

We review versions of the Generalized Uncertainty Principle (GUP) obtained in string theory and in gedanken experiments carried out in Quantum Gravity. We show how a GUP can be derived from a measure gedanken experiment involving micro-black holes at the Planck scale of spacetime. The model uses only Heisenberg principle and Schwarzschild radius and it is independent from particular versions of Quantum Gravity.
