Establishing homogeneity of the universe in the shadow of dark energy

Clarkson, Chris

Understand

Assuming the universe is spatially homogeneous on the largest scales lays the foundation for almost all cosmology.

This idea is based on the Copernican principle, that we are not at a particularly special place in the universe.
Surprisingly, this philosophical assumption has yet to be rigorously demonstrated independently of the standard paradigm.
This issue has been brought to light by cosmological models which can potentially explain apparent acceleration by spatial inhomogeneity rather than dark energy.
