论文摘要

哈勃张力驻留在哈勃常数的早期和晚期确定之间的统计学显着差异中。我们讨论椭圆形宇宙宇宙学模型中的哈勃张力。我们建议在大规模的空间几何形状中允许小小的各向异性可以减轻张力。我们还表明,如果我们在黑暗时代假设相当大的宇宙各向异性,则哈勃常数测量的差异将降低到统计上可接受的水平。此外,我们认为椭圆形宇宙宇宙学模型应解决$ S_8 $张力。

The Hubble tension resides in a statistically significant discrepancy between early time and late time determinations of the Hubble constant. We discuss the Hubble tension within the Ellipsoidal Universe cosmological model. We suggest that allowing small anisotropies in the large-scale spatial geometry could alleviate the tension. We, also, show that the discrepancy in the measurements of the Hubble constant is reduced to a statistically acceptable level if we assume sizeable cosmological anisotropies during the Dark Age. In addition, we argue that the Ellipsoidal Universe cosmological model should resolve the $S_8$ tension.
