**课程名称：** 天文学：宇宙中的“大”、“远”与“快”是相对的 **课程概述：** 本课程将挑战您对宇宙中大小、距离和速度的固有概念。“大”部分将通过将天体与我们熟悉的事物进行比较来探索宇宙的大小。“远”部分将带您进行一次跨越宇宙的旅行，从地面到太空，再到光速，让您真正理解太空的距离。“快”部分将讲解宇宙中和地球上的速度，以及速度如何影响物体本身以及周围的一切，甚至时间。 **课程亮点：** * **额外内容：** * “地球上的天文学是什么？” * “日食”迷你课程 * “流星雨”迷你课程 * “极光”迷你课程 * “阿尔忒弥斯计划：美国重返月球” * **核心内容（大、远、快）：** * **大：** 探索天体的大小，相对性概念，理解数字的含义，介绍最大恒星、星系的大小和距离。 * **远：** 通过各种旅行方式（汽车、飞机、航天飞机、光）理解距离，介绍行星、卫星、恒星、星云和星系的距离，探讨速度与距离的关系，以及地球和宇宙的形状。 * **快：** 讲解速度的相对性，速度的定义和局限，光速附近的时间膨胀效应，太空探索中的速度，牛顿运动定律，逃逸速度，宇宙中运动的测量难度，光、声与运动的关系，火箭，以及空白空间和宇宙。 **学习目标：** 通过本课程的学习，您将能够： * 理解并运用相对论的概念来描述宇宙中的大小、距离和速度。 * 能够通过比较来量化和理解宇宙天体的大小和距离。 * 了解不同速度对时间和空间的影响。 * 掌握天文学中的一些基本定律和概念，如牛顿运动定律，逃逸速度等。 * 认识到测量宇宙运动的挑战性。 **课程结构：** 课程分为“大”、“远”和“快”三个主要模块，每个模块都包含目标、热身活动、概念探索、实例分析、以及测试和跨学科活动。 **适合人群：** 对天文学感兴趣，希望拓宽视野，理解宇宙真实面貌的学习者。
This Course includes great BONUS LESSONS:What on Earth is Astronomy?Mini-Lesson: EclipsesMini-Lesson: Meteor ShowersMini-Lesson: AuroraProject Artemis: America Returns to the MoonBIG, FAR and FAST challenges your concept of what constitutes size, distance and speed in astronomical terms. BIG looks at size in the universe by comparing celestial objects with the sizes of things we are more familiar with close by. FAR takes you on an amazing trip around the universe on a plane, the space shuttle and finally a beam of light to understand how far things really are in space.FASTLearn about speed in space and on the Earth, and see how an object's movement effects the object and everything around it - even time.Big1.
