Homogeneous, Isotropic Universes

Part of the Astronomers’ Universe Series book series (ASTRONOM)


Hubble’s discovery that the Universe is expanding in such a way as to embody a speed distance law raises a variety of questions. For example, What kind of Universe has such features, and what are its other properties? Observation alone cannot provide the desired answers; theoretical investigation is required as well. The theoretical developments that yielded answers to these and some of the questions raised in earlier chapters began in 1915 when Albert Einstein produced the final version of the general theory of relativity. The growth of this theory into the one that dominated research on cosmology for so long is the theme of this chapter. I will first review some of the relevant history and then describe the meaning and some implications of a homogeneous, isotropic universe.
