This book is a gentle introduction for all those wishing to learn about modern views of the cosmos. Our universe originated in a great explosion – the big bang. For nearly a century cosmologists have studied the aftermath of this explosion: how the universe expanded and cooled down, and how galaxies were gradually assembled by gravity. The nature of the bang itself has come into focus only relatively recently. It is the subject of the theory of cosmic inflation, which was developed in the last few decades and has led to a radically new global view of the universe.

Students and other interested readers will find here a non-technical but conceptually rigorous account of modern cosmological ideas - describing what we know, and how we know it. One of the book's central themes is the scientific quest to find answers to the ultimate cosmic questions: Is the universe finite or infinite? Has it existed forever? If not, when and how did it come into being? Will it ever end?

The book is based on the undergraduate course taught by Alex Vilenkin at Tufts University. It assumes no prior knowledge of physics or mathematics beyond elementary high school math. The necessary physics background is introduced as it is required. Each chapter includes a list of questions and exercises of varying degree of difficulty.

This new edition includes hints for answering the questions and exercises, as well as extensions to the discussions on dark matter, quantum cosmology. A new chapter summarizing the standard cosmological model has also been added.

这本书是给所有希望了解现代宇宙观的读者的温柔入门。我们的宇宙起源于巨大的爆炸——大爆炸。近一个世纪以来，天文学家一直在研究这次爆炸后的后果：宇宙是如何膨胀并冷却下来的，以及如何通过引力逐渐组装出星系。大爆炸本身的性质最近才得以聚焦。这是广义相对论宇宙暴涨理论的主题，这一理论在过去的几十年里发展起来，并导致了我们对宇宙的全新全球视角。 学生和其他感兴趣的读者在这里会找到一个非技术性但概念严谨的现代天文学思想描述——讲述我们知道什么以及是如何知道的。这本书的一个中心主题是科学研究宇宙终极问题的科学追求：宇宙有限还是无限？它是否永远存在？如果不是，它是何时何地形成的？还会持续多久？ 本书基于阿列克谢·维林金在塔夫茨大学教授的本科生课程。它不需要任何基础物理学或数学知识（除了初中的基本知识）。必要的物理背景随需介绍。每章都包含一系列不同难度的问题和练习题单。 新版本增加了问题和练习题的答案提示，以及对暗物质、量子宇宙学讨论的扩展。还增加了一章总结标准宇宙模型。
