Query: String Gas Cosmology   String gas cosmology is a string theory-based approach to early universe
cosmology which is based on making use of robust features of string theory such
as the existence of new states and new symmetries. A first goal of string gas
cosmology is to understand how string theory can effect the earliest moments of
cosmology before the effective field theory approach which underlies standard
and inflationary cosmology becomes valid. String gas cosmology may also provide
an alternative to the current standard paradigm of cosmology, the inflationary
universe scenario. Here, the current status of string gas cosmology is
reviewed.
