  Some results are presented of the Earth's microseismic background. It is
assumed that background peaks should correspond to the resonance gravity-wave
exchange in the system of two gravity-connected bodies. The microseismic
spectrum is compared with the distribution of gravity potential of the nearest
stars. A close peak-to-peak correspondence is found. This correspondence and
resonance condition lead to an evaluation of the gravity-wave velocity. The
resulting value is nine orders of magnitude more than the velocity of light.
Some consequences of such result are discussed.
