And we can actually see the bending of light as it goes around a galaxy.

我们实际上可以看到光线在围绕星系旋转时弯曲。

This is all about the bending of light.

这都是关于光的弯曲的。

This can be seen in the bending of light from distant stars observed during an eclipse of the sun.

这可以从日食期间观察到的来自遥远恒星的光的弯曲中看出。

Also, gravity can bend light as Einstein showed us and we can actually see the bending of light as it goes around a galaxy.

同样，引力可以使光线弯曲，就像爱因斯坦给我们展示的那样，我们实际上可以看到光线围绕星系运动时的弯曲。

At its core, the formation of a rainbow involves two fundamental aspects of light behavior -- refraction (or bending of light) and reflection.

从本质上讲，彩虹的形成涉及光行为的两个基本方面——折射（或光的弯曲）和反射。
