According to model by Gorkavyi (Origin and Acceleration of the Universe without Singularities and Dark Energy, BAAS, 2003, 35, #3) a total energy of relic high-frequency gravitational radiation in our Universe can be very high. Relic plane gravitational waves can interact with stationary gravitational fields of galaxies and stars and create an additional ``relic acceleration'' that proportional to gravitational potential {~GM/(Rc2)} or angle of deflection of waves by a central mass. General equation for Newton and relic acceleration is {F = - \partial\varphi/\partial r + \alpha\varphi/c2} (1), where \varphi is gravitational potential; \alpha is vector that parallel {\partial\varphi/\partial r}; {\alpha~ 0.001-1 cm/sec2} and depends from size, density and strength of objects (all bodies in a sea of relic gravitational waves are gravitational detectors). From equation (1) for the anomalous acceleration of Pioneers that close to constant at heliocentric distance r we have: {F = -Gm/r2 - \alpha GM/(Rc2)} (2), where m is solar mass, {GM/(Rc2)} is potential of Galaxy, {\alpha = 0.127 cm/sec2} for solid object of small size like Pioneer. According (1)-(2) Pioneer acceleration depends from constant relativistic potential of Galaxy but is heliocentric due to strong gradient of solar potential. Similar or larger value of \alpha can be for stars and gas clouds, but for solid planets like Earth, \alpha can be few orders smaller due to high density, size larger than typical wavelength of relic gravitational waves, and fast dissipation of small-scale high-frequency mechanical oscillations inside solid body. According (1) relic acceleration for galaxies many times larger than Newton force, for galaxy cluster -- in a few orders. Laboratory experiment can reveal differences {~10-8 cm/sec2} in acceleration of objects with same mass but different sizes (1 vs. 2 m). Relic acceleration will decrease with a time due to decreasing density of energy of relic gravitational radiation and this effect can be a driver of galactic evolution.
