The isotropic blackbody CMB as evidence for a homogeneous universe

  title={The isotropic blackbody CMB as evidence for a homogeneous universe},
  author={T. Clifton and C. Clarkson and P. Bull},
The question of whether the Universe is spatially homogeneous and isotropic on the largest scales is of fundamental importance to cosmology, but has not yet been answered decisively. Surprisingly, neither an isotropic primary CMB nor combined observations of luminosity distances and galaxy number counts are sufficient to establish such a result. The inclusion of the Sunyaev-Zel’dovich effect in CMB observations, however, dramatically improves this situation. We show that even a solitary… Expand
