So Einstein said, well, let's make that a principle of nature, we'll call that the equivalence principle that gravity is equivalent to acceleration.

所以爱因斯坦总结出了一个自然原理，也就是引力等于加速度的等效原理。

So Einstein realized that this meant that if the equivalence principle is correct, then light would bend due to gravity in exactly the same way that it would bend due to constant acceleration.

所以爱因斯坦意识到，如果等效原理是正确的，那么光会以完全相同的方式受到重力的弯曲。
