当我们谈论宇宙学红移时，我们在谈论什么？
What do we talk about when we speak of cosmological redshift?
摘要：
从Slipher的第一次观测开始，我们对宇宙学红移的理解和解释就在不断发展，直到在广义相对论的框架内，通过膨胀的宇宙和现代物理宇宙学的出现，达到了目前的共识。红移是天文学最基本的概念之一，也是少数几个可以直接测量的观测参数之一。要提到宇宙中物体或宇宙结构的时间演化，我们经常通过宇宙时间或宇宙学红移模糊地这样做。但这种联系一再导致困惑，不仅在科学普及传播者中，而且在专业天文学界。在这篇文章中，我们将对宇宙时间和宇宙学红移之间的联系进行一种教学方法，我们也将澄清围绕这种关系的几个常见误解。
英文摘要：
From the first observations made by Slipher, our understanding and interpretation of the cosmological redshift was evolving until reaching the current consensus, through the expanding universe and the emergence of modern physical cosmology within the framework of General Relativity. The redshift is one of the most basic concepts of astronomy, and is one of the few observational parameters that can be measured directly. To refer to the temporal evolution of objects or cosmic structures in the universe, we often do so indistinctly through cosmic time or cosmological redshift. But repeatedly this connection ends up generating confusion not only among popular science communicators but also within the professional astronomical community. In this article, we will make a pedagogical approach to the link between cosmic time and cosmological redshift, and we will also clarify several common misunderstandings around this relation.
