Query: On Modelling a Relativistic Hierarchical (Fractal) Cosmology by Tolman's
  Spacetime. II. Analysis of the Einstein-de Sitter Model   This paper studies the spatially homogeneous Einstein-de Sitter cosmological
model in the context of a relativistic hierarchical (fractal) cosmology as
developed in paper I (0807.0866). The Einstein-de Sitter model is treated as a
special case of Lemaitre-Tolman's spacetime, obtained by the appropriate choice
of the latter's three arbitrary functions. The observational relations along
the past light cone of the model under consideration are calculated, and an
investigation of whether or not it has fractal behaviour is performed. It was
found that the Einstein-de Sitter model does not seem to remain homogeneous
along the geodesic and that it also has no fractal features along the backward
null cone.
