Einstein's Equations and a Cosmology with Finite Matter
  We discuss various space-time metrics which are compatible with Einstein's
equations and a previously suggested cosmology with a finite total mass. In
this alternative cosmology the matter density was postulated to be a spatial
delta function at the time of the big bang thereafter diffusing outward with
constant total mass. This proposal explores a departure from standard
assumptions that the big bang occurred everywhere at once or was just one of an
infinite number of previous and later transitions.
