Core Insights - The theme of the recent New Year's speech by Sohu's founder Zhang Chaoyang is "The Solar System We Live In," emphasizing the importance of understanding the solar system as a familiar yet distant home [1][3] - Zhang describes the exploration of celestial bodies as foundational to physics, highlighting the contributions of Tycho Brahe, Johannes Kepler, and Isaac Newton in uncovering universal truths [3] Group 1: Theoretical Foundations - Zhang uses Newton's laws as a first principle to logically reconstruct Kepler's laws, demonstrating the elliptical orbits and the relationship between orbital semi-major axes and orbital periods [3][4] - He explains tidal forces and their origins through gravitational potential, noting that extreme tidal forces can even destroy celestial bodies, as seen with Saturn's rings [4] Group 2: Exploration of the Solar System - The first stop in space exploration discussed is the Lagrange points, which are stable points in a two-body system where many space probes, like the Webb Telescope, are deployed [5] - The second stop is Mars, described as Earth's "twin," with a detailed explanation of the three-phase journey to reach it, emphasizing the fuel-efficient Hohmann transfer orbit [5] - The third stop involves the Voyager missions, which utilized gravitational slingshots to accelerate into deep space, showcasing the potential for future space exploration [6] Group 3: Future of Space Exploration - Concerns were raised about Earth's resource consumption and the need for accelerated space exploration, with Zhang indicating that Mars colonization is a distant goal, currently relying on robotic missions for resource collection [6] - Discussions included innovative propulsion methods, such as using comets for gravitational slingshots and solar pressure for spacecraft propulsion [6]
