Query: A new perspective on steady-state cosmology: from Einstein to Hoyle   We recently reported the discovery of an unpublished manuscript by Albert
Einstein in which he attempted a 'steady-state' model of the universe, i.e., a
cosmic model in which the expanding universe remains essentially unchanged due
to a continuous formation of matter from empty space. The manuscript was
apparently written in early 1931, many years before the steady-state models of
Fred Hoyle, Hermann Bondi and Thomas Gold. We compare Einstein's steady-state
cosmology with that of Hoyle, Bondi and Gold and consider the reasons Einstein
abandoned his model. The relevance of steady-state models for today's cosmology
is briefly reviewed.
