We show that it has a negligible influence on HYPER-like atomic interferometers although it may dominate decoherence of macroscopic motions, such as the planetary motion of the Moon around the Earth.9 pages, 4 figures, HYPER Symposium 2002 atomoptic.iota.u-psud.fr/hyper/Quantum PhysicsGeneral Relativity and Quantum Cosmologytext
