课程名称：宇宙大爆炸奇观：天文学、天体物理学、宇宙学 课程概述： 本课程“宇宙大爆炸奇观”将带领您踏上一段探索宇宙起源的旅程，主要借助詹姆斯·韦伯空间望远镜（JWST）的视角。我们将一起穿越一系列非凡的发现，这些发现对传统的宇宙大爆炸理论提出了引人入胜的问题和挑战。 宇宙大爆炸理论长期以来一直是关于我们宇宙诞生和演化的主流解释。从宇宙微波背景辐射到观测到的宇宙大尺度结构，大量证据都支持这一理论，它描绘了一幅宇宙起源于一个奇点的图景，并在过去138亿多年里不断膨胀，形成了我们今天观察到的宇宙。 随着我们深入宇宙的奥秘，詹姆斯·韦伯空间望远镜的出现为我们开启了新的视野。JWST 于2021年发射，是未来十年最重要的天文台，服务于全球数千名天文学家。它旨在解答天体物理学许多领域的广泛问题。 JWST 配备有一系列高度复杂的仪器，如近红外相机（NIRCam）、近红外摄谱仪（NIRSpec）和中红外仪器（MIRI），能够以多种光谱波长观测宇宙。这一能力打开了通往未知领域的大门，使我们能够回顾135亿多年前，看到最初的恒星和星系从宇宙黎明的黑暗中形成。 现在，站在宇宙启示的边缘，我们将踏上探索JWST十大关键发现的旅程，这些发现挑战了我们对宇宙大爆炸理论的理解。每个主题都将揭示宇宙奇观的一层面纱，从而加深我们对宇宙错综复杂结构的理解。
Welcome to "The Big Bang Mirage," a journey into the heart of our universe's origins through the lens of the James Webb Space Telescope. I'm your guide, Glen Cole, and together we'll traverse through the remarkable discoveries that have posed compelling questions and challenges to the conventional understanding of the Big Bang theory.The Big Bang theory has long stood as the prevailing explanation for the birth and evolution of our universe. Supported by a myriad of evidence, from the cosmic microwave background radiation to the observed large-scale structure of the universe, this theory has painted a picture of a universe originating from a singularity, and expanding for over 13.8 billion years to the cosmos we observe today.As we delve into the heart of cosmic mystery, we find ourselves at the threshold of new horizons with the advent of the James Webb Space Telescope. Launched in 2021, JWST is the premier observatory of the next decade, serving thousands of astronomers worldwide. It is designed to answer a wide range of questions across many fields of astrophysics.With its suite of highly sophisticated instruments like the Near Infrared Camera (NIRCam), Near Infrared Spectrograph (NIRSpec), and Mid-Infrared Instrument (MIRI), JWST is capable of observing the universe in multiple spectral wavelengths. This capability has opened the gates to uncharted territories, allowing us to peer back over 13.5 billion years to see the first stars and galaxies forming out of the darkness of the cosmic dawn.Now, as we stand on the brink of cosmic revelation, we embark on a journey to explore the ten key discoveries by JWST that challenge our understanding of the Big Bang theory. Each topic will unveil a layer of the cosmic mirage, fostering a deeper understanding of the universe's intricate tapestry.
