论文摘要
在这项工作中，我们研究了宇宙学的恒定问题和哈勃张力在空隙为主导的宇宙学方案\ cite {yusofi：2022hgg}。为了实现这一目标，我们将首先将宇宙网络中的宇宙空隙视为早期普朗克量表和晚期大型的理想球形气泡。通过每个宇宙空隙的启发式计算，我们获得了特定的质量密度和宇宙常数，在任何规模上都与整个宇宙相同。宇宙常数获得的值因量表而异。结果，将表明，当前的宇宙常数与Planck量表之间大致存在$ \ sim 10^{22} $。最后，将表明，宇宙气泡的表面张力之间的轻微差异可能解释了$ h _ {\ rm 0} $的本地和全局测量之间的张力。
In this work, we study the cosmological constant problem and Hubble tension in the void-dominated cosmology scenario \cite{Yusofi:2022hgg}. For this goal, we will first consider the cosmic voids in the cosmic web as interconnected ideal spherical bubbles at the early Planck scale and late large scale. By heuristic calculations for each cosmic void, we obtain particular mass density and cosmological constant that are the same order of magnitude as the entire universe on any scale. The values obtained for the cosmological constant vary from scale to scale. As a result, it will be shown that there is a roughly $\sim 10^{22}$ difference between the cosmological constant at the present and Planck scales. Finally, it will be shown that the slight difference between the surface tension of the cosmic bubbles may explain the tension between local and global measurements of $H_{\rm 0}$.
