量子引力中时空涌现的能级

Levels of spacetime emergence in quantum gravity

Daniele Oriti

摘要:

我们探讨了时空出现在量子引力的问题,通过阐明几个层次,这可以是有意的。这些能级对应于恢复时空的经典和连续概念所需的重建移动,在更基本的量子引力描述中,时空在越来越深的意义上逐渐丢失。它们也可以被理解为一个不断扩大视角的过程中的连续步骤,在每一步中揭示新的细节和新的问题。每一级都确实带来新的技术问题和机会,并提出新的概念问题。这加深了关于时空性质的辩论,无论是在物理上还是在物理上。

英文摘要:

We explore the issue of spacetime emergence in quantum gravity, by articulating several levels at which this can be intended. These levels correspond to the reconstruction moves that are needed to recover the classical and continuum notion of space and time, which are progressively lost in a progressively deeper sense in the more fundamental quantum gravity description. They can also be understood as successive steps in a process of widening of the perspective, revealing new details and new questions at each step. Each level carries indeed new technical issues and opportunities, and raises new conceptual issues. This deepens the scope of the debate on the nature of spacetime, both philosophically and physically.
