- This phenomenon is called the equivalence principle, which states that an object that is accelerating free of any gravitational pull is essentially no different than the same object that is stationary but affected by gravity.
這種現象被稱為 "等效原理"，即一個物體在沒有任何引力的情況下加速，與靜止但受引力影響的物體沒有本質區別。
- This means that regardless of whether the light beam is traveling freely or under the gravitational field, it must take the same time for it to travel from A to B.
這意味著，無論光束是自由傳播還是在引力場作用下傳播，它從 A 到 B 所需的時間都是相同的。
