These fees can add up, but whether or not you incur them is up to you.

这些费用可以相加，而是你是否动用他们是你的。

We know that light in inertial reference frame, and naturally to meet the speed of the sum theorem in classical mechanics (because so far we have not found exception to overthrow it is the inertial basis).

我们知道，光处在惯性系中，自然也就满足经典力学中速度相加定理（因为至今我们还没有找到推翻它是惯性系中特例的依据）。
