Abstract
The pattern of motion of test bodies in space-time described by the anisotropic Kasner solution is studied. Distances and velocities are determined by the methods used in astronomical observations. The motion can be described by the anisotropic Hubble parameter, which depends on the position of the object in the sky. The observed anisotropy decreased over time inversely proportional to the age of the universe, falling below any given threshold for all celestial bodies within a sphere of fixed radius.
Key words
