1846年,天文学家注意到天王星以一种与牛顿第一定律相矛盾的规律偏离正常轨道“摆动”。这意味着科学家们只有两种选择:要么重写牛顿的物理定律,要么“发明”一颗新的行星来解释这种奇怪的重力拖曳现象。结果,天文学家们发现了“海王星”。今天,科学家们又遇到了相同的难题。路易斯安那大学的天文学家约翰·马特斯、帕特里克·威特曼和丹尼尔·威特米尔研究彗星轨道已有20多年的历史了。他们在研究了82颗来自遥远的奥特星云
In 1846, astronomers noted that Uranus deviated from the normal orbit by a law that contradicted Newton’s first law. This means that scientists have only two choices: either to rewrite Newton’s physical laws or “invent” a new planet to explain this strange gravity drag phenomenon. As a result, astronomers discovered “Neptune.” Today, scientists have encountered the same problem. The University of Louisiana astronomers John Matters, Patrick Wittman, and Daniel Whitmer have studied comet orbit for more than 20 years. They are studying 82 satellites from the distant Ott nebula
