量子世界时空观的反思
Reflections on the Spatiotemporal Aspects of the Quantum World
摘要：
所谓的测量问题的正确解决需要一个“自上而下”的量子世界概念，这与通常的“自下而上”的概念相反，后者建立在一个内在的和最大可微的流形上。这个问题的关键在于，变量的模糊性只有在模糊性较小的变量存在的情况下才能表现出来。由于没有什么比度规更模糊的了，这就反对量子引力现象学，并表明引力的量子理论在术语上是矛盾的--一种使研究不存在的尺度上的物理学成为可能的理论，或者研究没有物理后果的尺度的物理后果，除了为粒子物理学的量子场论提供一个自然截止之外。
英文摘要：
The proper resolution of the so-called measurement problem requires a "top-down" conception of the quantum world that is opposed to the usual "bottom-up" conception, which builds on an intrinsically and maximally differentiated manifold. The key to that problem is that the fuzziness of a variable can manifest itself only to the extent that less fuzzy variables exist. Inasmuch as there is nothing less fuzzy than the metric, this argues against a quantum-gravity phenomenology and suggests that a quantum theory of gravity is something of a contradiction in terms - a theory that would make it possible to investigate the physics on scales that do not exist, or to study the physical consequences of a fuzziness that has no physical consequences, other than providing a natural cutoff for the quantum field theories of particle physics.
