Quantum gravity is quite elusive at the experimental level; thus a lot of interest has been raised by recent searches for quantum gravity effects in the propagation of light from distant sources, such as gamma ray bursters and active galactic nuclei, and also in Earth-based interferometers, such as those used for gravitational wave detection. Here we propose a simple heuristic picture of the quantum fluctuations of the gravitational field and use it to set up a mathematical framework to estimate quantum gravity effects in interferometers. We also discuss some other developments suggested by these heuristics.

Abstract
Quantum gravity is quite elusive at the experimental level; thus a lot of interest has been raised by recent searches for quantum gravity effects in the propagation of light from distant sources, such as gamma ray bursters and active galactic nuclei, and also in Earth-based interferometers, such as those used for gravitational wave detection. Here we propose a simple heuristic picture of the quantum fluctuations of the gravitational field and use it to set up a mathematical framework to estimate quantum gravity effects in interferometers. We also discuss some other developments suggested by these heuristics.File in questo prodotto:
