Gpc径向尺度以上哥白尼原理的验证

哥白尼原理是现代宇宙学的基石之一.但是,Gpc径向尺度以上的哥白尼原理几乎没有得到确证.如果该类哥白尼原理遭到破坏,就会产生一阶各向异性运动学SZ（Sunyaev Zel＇dovich）效应.我们证明,如果这种破坏达到能够取代暗能量解释宇宙＂加速＂膨胀的程度,产生的运动学SZ效应功率谱将远远超出ACT/SPT实验的上限.该检验排除了空洞模型解释宇宙＂加速＂膨胀的可能性,证实了Gpc径向尺度以上的哥白尼原理,弥补了标准宇宙学中的一个漏洞.

Confirmation of the Copernican principle at Gpc radial scale and above

The Copernican principle remains largely unproven at Gpc radial scale and above. Violations of this type in general 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 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.
