确定方向

The difference of opinion arises because, where events occur in separated locations, both sets of observers have to make calculations before they can decide on the simultaneity or otherwise of separated events; they have to make allowance for the time it has taken for the light signals to travel from the distant locations, and both insist that the speed of light is a constant in all directions relative to them.

不同的观点就出现了，因为在事件发生的两个地方的两组观察者在确定事件是否同时发生之前都必须先经过计算；他们必须扣除光信号从远处传来时所耗的时间，而同时，他们又都坚信光速在相对他们的所有方向上都是恒速的。
