ABSTRACT
One aspect of cosmology deals with the actual geography of matter; the question of importance is where the matter is and what it is doing there. The relevant observations are of how many galaxies are East or West and in what direction they are moving. The problems of cosmology are always tied up with some fundamental assumptions. Cosmological problems of a different nature appear when the authors go to such an enormous scale that the detailed structure should disappear. The grand hypothesis that nearly every cosmologist makes is that the universe looks the same no matter where one may be in it—although not necessarily simultaneously. The other cosmological theories sweep creation of matter under the rug by simply assuming a time at which the matter was already there, and speaking only of what comes after.
