An observer. situated several thousand light-years away from a radio pulsar, finds himself embedded in the diffraction pattern resulting from the propagation of the radio waves through the irregular interstellar medium. The gravity waves produced by an intervening binary star cause the diffraction pattern to be displaced laterally in a manner familiar from refractive interstellar scintillation, except that this gravity wave effect is not dispersive. This periodic displacement can reach a few hundred kilometers. Thus, there seems to be a possibility that the exceedingly faint gravity waves can manifest themselves macroscopically.
