论文摘要
宇宙学范围的一种新型分形结构，其灵感来自Covid-19的几何形状，从而实现了修改的区域熵，用于宇宙学以服务暗能量。基于完整的观察数据集的约束将得出。与标准的$λ$ CDM模型相比，有强有力的贝叶斯证据支持这种暗能量，并且这种能量不能简化为宇宙常数。此外，朝着较小的BARYON密度参数和较大的哈勃参数值的值转变，从而降低了哈勃张力。
A novel fractal structure for the cosmological horizon, inspired by COVID-19 geometry, which results in a modified area entropy, is applied to cosmology in order to serve dark energy. The constraints based on a complete set of observational data are derived. There is a strong Bayesian evidence in favor of such a dark energy in comparison to a standard $Λ$CDM model and that this energy cannot be reduced to a cosmological constant. Besides, there is a shift towards smaller values of baryon density parameter and towards larger values of the Hubble parameter, which reduces the Hubble tension.
