哥白尼原理是现代宇宙学的基石，在Gpc径向尺度和更高尺度上仍然没有得到证实。这里将表明，这种类型的违反将不可避免地导致一阶各向异性动力学Sunyaev-Zel'dovich效应。如果大尺度的径向不均匀性有足够大的振幅来解释“暗能量”现象，则诱导的动力学Sunyaev-Zel'dovich功率谱将远远大于阿塔卡玛宇宙望远镜和/或南极望远镜的上限。这个单一的测试证实了哥白尼原理，并排除了绝热空隙模型作为暗能量的可行替代品。
The Copernican principle, a cornerstone of modern cosmology, remains largely unproven at the Gpc radial scale and above. Here will show that violations of this type will inevitably cause a first order anisotropic kinetic Sunyaev-Zel'dovich effect. If large scale radial inhomogeneities have an amplitude large enough to explain the "dark energy" phenomena, the induced kinetic Sunyaev-Zel'dovich power spectrum will be much larger than the Atacama Cosmology Telescope and/or South Pole Telescope upper limit. This single test confirms the Copernican principle and rules out the adiabatic void model as a viable alternative to dark energy.
