The Hubble flow: an observer’s perspective

Lomonosov Moscow State University, Shternberg State Astronomical Institute, Universitetskii prosp. 13, Moscow, 119889, Russian Federation

This paper discusses some aspects of cosmological expansion as viewed by an observer. It identifies the rate of change of the angular distance v&Theta with respect to the observer’s clock as a crucial quantity in adequately understanding the expansion. Using this quantity and the angular distance in addition to the traditional illustration approach provides a more vivid picture of the cosmological expansion and is key for its adequate visualization.
