法比歐．帕庫西: 解釋牛頓的三體問題

解釋牛頓的三體問題

2009 年，研究者做了一項簡單的實驗。他們用上了我們對太陽系所知的一切，去計算五十億年後每一顆行星的所在。他們進行了超過兩千次數值模擬，而結果驚人的多樣性表示我們的太陽系可能沒有看起來這麼穩定。法比歐．帕庫西要帶大家來探究 N 體問題以及受引力影響的物體會如何運動。

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.
