论文摘要
我们认为，存在一种建立空间和时间概念的可观察性的操作方法。具体而言，我们为Gedanken实验提出了一种独立于理论的方案，该方案的结果是建立了时空流形的可观察力的信号，而没有先验地假设其存在。实验信号包含有关时空的维度和拓扑（具有当前可实现的精度）的信息，并建立了其歧管结构，同时尊重其潜在的差异对称性。我们还介绍并讨论了时空出现概念的适当标准，任何暂定的物理学理论模型都必须满足，以声称时空确实从一些更基本的概念中浮现出来。
We argue that there exists an operational way to establish the observability of the notions of space and time. Specifically, we propose a theory-independent protocol for a gedanken-experiment, whose outcome is a signal establishing the observability of the spacetime manifold, without a priori assuming its existence. The experimental signal contains the information about the dimension and the topology of spacetime (with the currently achievable precision), and establishes its manifold structure, while respecting its underlying diffeomorphism symmetry. We also introduce and discuss appropriate criteria for the concept of emergence of spacetime, which any tentative theoretical model of physics must satisfy in order to claim that spacetime does emerge from some more fundamental concepts.
