**Cosmic Structure, Averaging and Dark Energy**

by David L. Wiltshire

**Publisher**: arXiv 2013**Number of pages**: 55

**Description**:

These lecture notes review the theoretical problems associated with coarse-graining the observed inhomogeneous structure of the universe at late epochs, of describing average cosmic evolution in the presence of growing inhomogeneity, and of relating average quantities to physical observables. In particular, a detailed discussion of the timescape scenario is presented.
