The standard model
Inhomogeneous cosmologies
The standard model of cosmology assumes a homogeneous and isotropic universe, and as a description of the bulk properties of the universe, it has served us well. But the real universe is distinctly non-homogeneous on all scales except possibly the largest, so it is important to study the behaviour of inhomogeneities. Inhomogeneous cosmology uses exact solutions of the Einstein field equations to explore the full non-linear evolution of inhomogeneous structures.

The Metric of the Cosmos. This is the ultimate application of Einstein�s field equations � determining the relation between matter and geometry in the real universe. The idea of reducing observed cosmological data to a metric was first explicitly discussed by Kristian & Sachs in 1966. Though a fair bit of theoretical development has been done, the methods have never been implemented, and therefore key questions such as choosing appropriate numerical methods, anaylysing uncertainties, and how to handle the intricacies of real observational data, etc, have not been addressed. A numerical reduction scheme is being developed and tested with fake data.

The large amounts of cosmological data generated by current and future redshift surveys will make this project practicable in the near future. This data will allow us to move beyond the assumption of homogeneity, and instead quantify the degree of homogeneity or lumpiness on a metric level. More importantly, as the data becomes increasingly accurate, the proper reduction and interpretation of the high redshift data will require knowledge of the cosmic geometry that is traveled through by the light rays we observe.

Our universe in reality has parts that are expanding and parts that are contracting.

In addition we find extremely large voids billions of year across that the big bang cannot explain.
