At the root of this strange time warping effect lies Einstein's postulate that the speed of light should be the same for all observers, no matter how fast they are moving.

实际上，根据爱因斯坦假设的时间隧道效应，光速在所有观察者眼中是不变的，无论他们移动的多快。

The constancy of the speed of light essentially underpins our understanding of space and time and causality, which is the fact that cause comes before effect.

光速常数实质上支撑着我们对于空间、时间和因果关系的理解。我们都相信因在果之前的事实。

Lightmapping can't be calculated for moving objects in real time, but it's possible to get a similar effect that you would get with dynamic lights by using light probes.

光照贴图无法为移动中的物体进行实时计算，但是通过为动态光源使用灯光探测器，还是可以达到非常接近的效果。

Jack Ng and his colleagues at the University of North Carolina, Chapel Hill, have written a paper arguing that Dr Lieu overestimated by a factor of several million the effect that fluctuations in space and time would have on light.
