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 .
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 .
