We develop the dynamical approach in this model and investigate
nonrelativistic motion of two, three and even more cosmic bodies against the
cosmological background, perturbed locally by density inhomogeneities (namely,
galaxies). For arbitrary initial conditions, we get solutions of equations of motion
(trajectories), demonstrating most important features of the cosmological expansion,
only slightly restrained by gravitational attraction. Our methods can be used for
indirect observations of dark energy and dark matter
