  • Parallel worlds are a topic of science fiction  that seem to come up over and over again. Lately,  

    平行世界是科幻小說的一個話題,似乎一次又一次地出現。最近。

  • the number of shows and movies featuring branching  timelines and multiverses have been multiplying,  

    以分支時間線和多重世界為特色的節目和電影的數量一直在增加。

  • and you may be low-key wondering just how  much of the fiction resembles reality

    而你可能會低調地想知道,這些虛構的東西有多少與現實相似。

  • Scientists have been asking these same questions  for decades because from what we've seen,  

    科學家們幾十年來一直在問這些同樣的問題,因為從我們看到的情況來看。

    確定性:如果你知道某個東西的速度和位置,比如一個在空中飛行的球。

  • then you can predict where  the ball is going to land

    那麼你就可以預測球的落點。

  • But in the quantum worldthings don't work like that.  

    但在量子世界裡,事情並不是這樣的。

  • It is impossible to know the exact speed  and position of a particle like an electron,  

    要知道像電子這樣的粒子的確切速度和位置是不可能的。

  • and so it is impossible to say for certain  what it will do, only the probabilities

    是以,不可能肯定地說它會做什麼,只能說是概率。

    最廣泛接受的是哥本哈根解釋。它指出波函數

  • collapse when they are observed, measured, or  interact with the classical world in some way

    在同一時間,只要沒有人看裡面。但如果我們看錯了呢。
