Abstract: We have derived
generalized ideal gas equations for a structureful universe consisting
of all forms of matters. We have assumed a universe that contains
superclusters. Superclusters are
then made of clusters. Each cluster can be further divided into smaller
ones and so on. We have
derived an expression for the entropy of such a universe. Our model is
rather independent of the
geometry of the intermediate clusters. Our calculations are valid for a
non-interacting universe
within non-relativistic limits. We suggest that structure formation can
reduce the expansion rate
of the universe.
Keywords: set theory; cluster;
temperature; pressure; entropy; thermal energy; cosmology.
