Abstract
Various results are obtained for a Friedmann-Robertson-Walker cosmology. We derive an exact equation that determines Hubble's law, clarify issues concerning the speeds of faraway objects and uncover a "tail-light angle effect" for distant luminous sources. The latter leads to a small, previously unnoticed correction to the parallax distance formula.
