Our result derives from this concept of macroscopic observables being a kind of average .

我们的结果源自把宏观可观测量看做某种平均的概念。

So either closed timelike curves cannot exist , or big , macroscopic things cannot travel on truly closed paths through space-time-unless everything we think we know about entropy and the arrow of time is wrong .

因此，既不可能存在封闭的时间型曲线，肉眼可见的大型物体也不可能以真正封闭的路径穿梭时空，除非我们觉得关于一致性和时间的箭头的所有看法都是错的。

Keeping track of all that information is not feasible in practice , but we can average the microscopic behaviour to derive a macroscopic description .

可是跟踪实际状态下的所有的信息是不可行的，但我们可以把微观表现平均起来使之形成一个宏观的描述。

Analysing the statistics , we find that local realism emerges for macroscopic correlations without us needing to invoke any other mechanism .

分析了统计信息，我们发现，不借助于任何其他机制，宏观相关性的定域现实性就会显现出来。

One thing we have neglected to say so far is that einstein 's theory , which describes the macroscopic world so admirably well , doesn 't work for the microscopic world .

目前为止，有一件事被我们一直忽略，那就是爱因斯坦的理论对于宏观世界的描述非常完美，但是他的理论在微观世界就行不通了。
