Could we observe the discreteness of Quantum-Gravity length and area operators ?
Giovanni Amelino-Camelia
Abstract
Several proposals for Quantum Gravity involve length and area operators with discrete eigenvalues. I show that the analyses of some simple procedures for the measurement of areas and lengths suggest that this discreteness characterizing the formalism might not be observable. I also discuss a possible relation with the so-called κ deformations of Poincare' symmetries.
