内在观察者产生的时间

Time generated by intrinsic observers

Karl Svozil

摘要:

我们简要回顾一下内在观察者对知识的建构。内在观测器嵌入在系统中,是系统不可分割的一部分。内在的观点必须与外在的“上帝之眼”的观点相对照,从外在的角度来看,系统可以在不以任何方式改变它的情况下被观察到。结果之一是出现了“互补性”的内在观察者,即使底层系统是完全确定的(可计算)。另一个结果是内在观察者的时间和惯性系的出现。必要的操作技术是在元胞自动机的背景下开发的。我们以一个有点投机的问题结束。既然时空框架是由使用声波同步的时钟产生的,为什么超音速旅行不会引起时间悖论?

英文摘要:

We shortly review the construction of knowledge by intrinsic observers. Intrinsic observers are embedded in a system and are inseparable parts thereof. The intrinsic viewpoint has to be contrasted with an extrinsic, "God's eye" viewpoint, from which the system can be observed externally without in any way changing it. This epistemological distinction has concrete, formalizable consequences. One consequence is the emergence of "complementarity" for intrinsic observers, even if the underlying system is totally deterministic (computable). Another consequence is the appearence of time and inertial frames for intrinsic observers. The necessary operational techniques are developed in the context of Cellular Automata. We finish with a somewhat speculative question. Given space-time frames generated by clocks which use sound waves for synchronization; why could supersonic travel not cause time paradoxes?
