问题各向同性
Question Isotropy
摘要：
“宇宙学原理”在早期建立时并没有意识到它对视界问题的影响，而且几乎完全没有观测数据的支持。在电磁传播、类星体极化和$CMB$温度图的数据中发现了一致的各向异性信号。室女座的轴被发现一次又一次地在信号打破各向同性，从独立的能量制度的独立可观的。在传统的天体物理学中，对这些效应还没有令人满意的解释。轴子凝聚体中的轴子-光子混合和传播能够包含这些数据。
英文摘要：
The "cosmological principle" was set up early without realizing its implications for the horizon problem, and almost entirely without support from observational data. Consistent signals of anisotropy have been found in data on electromagnetic propagation, polarizations of QSOs and $CMB$ temperature maps. The axis of Virgo is found again and again in signals breaking isotropy, from independent observables in independent energy regimes. There are no satisfactory explanations of these effects in conventional astrophysics. Axion-photon mixing and propagation in axion condensates are capable of encompassing the data.
