Experimental Tests of Quantum Gravity and Exotic Quantum Field Theory Effects
Abstract
The spacetime around Earth is a good environment in order to perform tests of gravitational theories.According to Einstein's view of gravitational phenomena, the Earth mass-energy content curves the surrounding spacetime in a peculiar way.This (relatively) quiet dynamical environment enables a good reconstruction of geodetic satellites (test masses) orbit, provided that high-quality tracking data are available.This is the case of the LAGEOS satellites, built and launched mainly for geodetic and geodynamical purposes, but equally good for fundamental physics studies.A review of these studies is presented, focusing on data, models, and analysis strategies.Some recent and less recent results are presented.All of them indicate general relativity theory as a very good description of gravitational phenomena, at least in the studied environment.
