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“发现”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”的存在。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· In 1846, astronomers noticed that Uranus deviated from the normal orbit by a law that contradicted Newton’s first law, which meant that scientists had only two choices: either to rewrite Newton’s laws of physics or to “discover” one. A new planet explains this strange gravity drag phenomenon. As a result, astronomers discovered the existence of “Neptune”. Today, scientists have encountered the same problem.
