宇宙真的在膨胀吗？
Is the Universe really expanding?
摘要：
哈勃定律是根据星系的距离模和红移确定的，在过去的80年里，它一直被用作宇宙膨胀的有力证据。这一说法是根据声称缺乏必要的证据，时间膨胀的类星体和伽马射线暴光度变化和其他证据。它的结论是，观测结果可以用来描述一个静态的宇宙（哈勃定律的结果从一些尚未未知的机制）或膨胀的宇宙所描述的标准λ冷暗物质模型。在后一种情况下，星系的大小演化是必要的，以符合观测。然而，简单的非膨胀欧几里德宇宙用最少的假设来拟合大多数数据。从这篇评论中可以看出，宇宙学中仍然有许多未回答的问题，本文的标题问题仍然远远没有得到回答。
英文摘要：
The Hubble law, determined from the distance modulii and redshifts of galaxies, for the past 80 years, has been used as strong evidence for an expanding universe. This claim is reviewed in light of the claimed lack of necessary evidence for time dilation in quasar and gamma-ray burst luminosity variations and other lines of evidence. It is concluded that the observations could be used to describe either a static universe (where the Hubble law results from some as-yet-unknown mechanism) or an expanding universe described by the standard Lambda cold dark matter model. In the latter case, size evolution of galaxies is necessary for agreement with observations. Yet the simple non-expanding Euclidean universe fits most data with the least number of assumptions. From this review it is apparent that there are still many unanswered questions in cosmology and the title question of this paper is still far from being answered.
