【 摘 要 】

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.
