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 matterencosmic bodieshyperbolic spaceDynamics of cosmic bodies in TNK open UniverseArticle
