The Copernican principle remains largely unproven at Gpc radial scale and above. Generally, violations of this type 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 Atacama cosmology telescope/South Pole telescope upper limit. This single test rules out the void model as the cause of the apparent cosmic acceleration, confirms the Copernican principle on Gpc radial scale and above, and closes a loophole in the standard cosmology.
哥白尼原理在 Gpc 径向尺度及以上仍未得到充分验证。一般来说，此类违反会导致一阶各向异性动力学 Sunyaev-Zel'dovich (kSZ) 效应。在这里，我们表明，如果大尺度径向不均匀性的幅度足够大，足以解释“暗能量”现象，那么诱导的 kSZ 功率谱将比阿塔卡马宇宙学望远镜/南极望远镜的上限大几个数量级。这一单一测试排除了虚空模型作为宇宙加速的原因，证实了 Gpc 径向尺度及以上的哥白尼原理，并填补了标准宇宙学中的一个漏洞。
