现代宇宙学,一个有趣的游戏
Modern Cosmology, an Amuse-Gueule
摘要:
这篇文章是面向更广泛读者的非技术性入门读物,我在其中描绘了现代宇宙学的大致图景。我首先回顾了大爆炸的证据,包括我们宇宙的膨胀、宇宙微波背景和轻元素的原始丰度。接下来,我将讨论如何通过宇宙学的和谐模型很好地解释这些和其他宇宙学观测,特别强调宇宙能量收支的组成,包括可见物质、暗物质和暗能量。这为我们简要概述宇宙的历史奠定了基础,从它存在的最早时刻一直到晚期及以后的加速膨胀。最后,我总结了该领域的现状,包括它目前面临的挑战,如哈勃望远镜的紧张局势,并展望了未来几年和几十年等待我们的光明未来。文本是由一个广泛的参考书目作为指导读者谁希望深入研究补充。
英文摘要:
This essay is a nontechnical primer for a broader audience, in which I paint a broad-brush picture of modern cosmology. I begin by reviewing the evidence for the big bang, including the expansion of our Universe, the cosmic microwave background, and the primordial abundances of the light elements. Next, I discuss how these and other cosmological observations can be well explained by means of the concordance model of cosmology, putting a particular emphasis on the composition of the cosmic energy budget in terms of visible matter, dark matter, and dark energy. This sets the stage for a short overview of the history of the Universe from the earliest moments of its existence all the way to the accelerated expansion at late times and beyond. Finally, I summarize the current status of the field, including the challenges it is currently facing such as the Hubble tension, and conclude with an outlook onto the bright future that awaits us in the coming years and decades. The text is complemented by an extensive bibliography serving as a guide for readers who wish to delve deeper.
