论文摘要
基于标准的$λ$ CDM宇宙学对哈勃常数的最新测量表明，早期宇宙估计值与晚期测量之间存在基本分歧。此外，随着这些测量结果的改善，差异不仅存在，而且变得更加重要和难以忽视。当前情况将标准宇宙学置于危险中，并提供了一个诱人的提示，即问题是由于$λ$ CDM模型以外的一些新物理学引起的。 结果表明，非惯性理论 - 米尔恩模型 - 引入了宇宙的不同演化动力学，可大大减轻哈勃张力。此外，该模型还避免了标准宇宙学的一些长期问题，例如，与宇宙常数，地平线，平坦度，大爆炸奇异性，宇宙时代和能量不保存有关的问题。
The recent measurements of the Hubble constant based on the standard $Λ$CDM cosmology reveal an underlying disagreement between the early-Universe estimates and the late-time measurements. Moreover, as these measurements improve, the discrepancy not only persists but becomes even more significant and harder to ignore. The present situation places the standard cosmology in jeopardy and provides a tantalizing hint that the problem results from some new physics beyond the $Λ$CDM model. It is shown that a non-conventional theory - the Milne model - which introduces a different evolution dynamics for the Universe, alleviates the Hubble tension significantly. Moreover, the model also averts some long-standing problems of the standard cosmology, for instance, the problems related with the cosmological constant, the horizon, the flatness, the Big Bang singularity, the age of the Universe and the non-conservation of energy.
