2009 年，研究人员进行了一项简单实验。他们利用我们对太阳系的了解，计算出了每颗行星在 50 亿年后的位置。他们进行了 2000 多次模拟，结果的惊人变化表明，我们的太阳系可能远没有看上去那么稳定。法比奥·帕库奇（Fabio Pacucci）探究了 N 体问题和引力物体的运动。

Even the tiniest change in Mercury’s orbit can set off cosmic chaos, as researchers discovered when one simulation out of 2,000 sent planets colliding after billions of years. The n-body problem reveals that predicting the motion of three or more gravitating bodies is impossible to solve with a single formula. Instead, their behavior is wildly sensitive to initial conditions and can lead to unexpected, even catastrophic, outcomes. Powerful computer simulations help us navigate this unpredictability and maintain confidence in the solar system’s stability for now.
