Title: Confirmation of the Copernican principle at Gpc radial scale and above from the kinetic Sunyaev Zel'dovich effect power spectrum

Abstract

The Copernican principle, a cornerstone of modern cosmology, remains largely unproven at Gpc radial scale and above. Violations of this type will inevitably cause a first order anisotropic kinetic Sunyaev Zel'dovich (kSZ) effect. Here we show that, if large scale radial inhomogeneities have amplitude large enough to explain the 'dark energy' phenomena, the induced kSZ power spectrum will be orders of magnitude larger than the ACT/SPT upper limit. This single test rules out the void model as a viable alternative to dark energy to explain the apparent cosmic acceleration, confirms the Copernican principle on Gpc radial scale and above and closes a loophole in the standard cosmology.
