TL;DR
This paper reviews various forms of the Generalized Uncertainty Principle (GUP) derived from string theory and thought experiments, proposing a model based on micro-black holes that is independent of specific quantum gravity theories.
Contribution
It introduces a GUP derivation from a thought experiment involving micro-black holes, using only fundamental principles, independent of particular quantum gravity models.
Findings
GUP can be derived from micro-black hole gedanken experiments
The model relies solely on Heisenberg principle and Schwarzschild radius
The approach is independent of specific quantum gravity theories
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.
