"第一年的时候，我们讲了广义相对论，而去年是量子力学的一天，今天我们要看看生存的太阳系。"12月31日晚10点，搜狐创始人、董事局主席兼首席 执行官、物理学博士张朝阳如期开启他的第三场跨年演讲。 这场以"我们所居住的太阳系"为主题，太阳系以什么秩序在运转？月球为何始终以同一面朝向地球？人类如何抵达火星？演讲现场，张朝阳用数理公式 一步步演算着这些宇宙谜题。 我们的太阳系有太多奥秘等待探索，人类不可能永远停留在地球摇篮里。在演讲下半场，张朝阳带观众们领略了飞出地球的三个站点。 张朝阳认为，当下AI和航天技术的发展，正推动人类逐步迈"多行星文明"。"了解太阳系的运行规律，正是理解人类文明来处与未来方向的关键。"他 说。 行星的运动自有秩序，牛顿定律勾勒太阳系大格局 "太阳系不是遥远的不可知，而是又近又远的家园，我们需要了解与我们息息相关的太阳系。"张朝阳说。 这场演讲又被张朝阳戏称为对太阳系的大"考古"，而牛顿的运动定律和引力定律无疑是发掘这段历史的"洛阳铲"。他介绍，正是人类对太阳系各大天体 的探索带来了物理学：第谷一生积累的观测数据启发了开普勒写下三大定律，而站在两位巨人肩膀上的牛顿，最终揭示了更具普遍性的真 ...

Core Viewpoint - The keynote speech by Zhang Chaoyang focuses on understanding the solar system and its significance for humanity's future, particularly in the context of advancing AI and space technology towards a multi-planetary civilization [1][3]. Group 1: Understanding the Solar System - The solar system operates under specific laws, with Newton's laws providing a framework for understanding planetary motion [3][4]. - Zhang emphasizes that the solar system is not distant and unknown but rather a familiar home that requires understanding [3][6]. - The exploration of celestial bodies has led to significant advancements in physics, with historical figures like Tycho Brahe and Kepler contributing to our understanding of planetary motion [3][4]. Group 2: The Role of Tidal Forces - Tidal forces play a crucial role in the behavior of moons and planets, affecting their orbits and physical characteristics [6][8]. - Zhang explains how tidal forces can lead to phenomena such as the synchronous rotation of the Moon and the volcanic activity on Io, one of Jupiter's moons [8][9]. Group 3: Human Exploration of Space - The speech outlines three key stages for human exploration beyond Earth, starting with Lagrange points, which are stable locations for deploying spacecraft [9][11]. - Mars is highlighted as a potential destination for human exploration due to its similarities to Earth, with a detailed explanation of the Hohmann transfer orbit for efficient travel [9][11]. - The Voyager missions are noted as significant milestones in humanity's exploration of the outer solar system, utilizing gravitational assists to increase speed [11][12]. Group 4: Scientific Foundation for Speculation - Zhang stresses the importance of grounding speculative ideas in solid scientific principles, particularly in discussions about future space colonization [12][14]. - The audience is encouraged to engage with scientific concepts before delving into speculative scenarios, ensuring a robust understanding of physics [14][15]. Group 5: Educational Impact and Engagement - The integration of traditional teaching with new media has proven effective, with Zhang's physics classes reaching a wide audience and contributing to public knowledge [15][17]. - The emphasis on rigorous mathematical foundations in science education is highlighted as essential for fostering a deeper understanding of complex topics [15][17].
