地球将不得不与另一个星球或整个恒星系统碰撞,以成为流氓星球。恒星看起来很静态,但它们以每秒250公里的惊人速度行驶,甚至遇到这种速度的一小部分。
在银河系中,可能有数十亿美元的流氓行星(不圆形恒星的行星)的数十亿美元(即使不是数万亿个行星)。在下面的视频中,库尔兹格盖特(Kurzgesagt)讨论了地球如何流氓(通过沿着附近的巨星远离太阳),如果发生这种情况,我们的海洋,氛围和生活会发生什么。
The first portion of the video is tragic — “as the days turn dark, the final winter of humanity would begin” — but the second half is positive: we’ll be able to forecast our expulsion thousands of years in advance and may be able to prepare. Given the global response to the pandemic and climate change, it would be fascinating to watch if human civilization could band together to save itself from a harsh end in space.
