论文摘要
在引力领域的任何理论中，时空，时间和物质的概念都是至关重要的。在这里，我讨论了这些概念在重力理论中可能起的作用。要具体，我将重点关注最保守的方法，即量子几何动力学。事实证明，时空在最基本的水平上是不存在的，并且仅在适当的限制下出现。可以预期，只有从所有相互作用的基本量子理论中才能理解物质的动力学。
The concepts of space, time, and matter are of central importance in any theory of the gravitational field. Here I discuss the role that these concepts might play in quantum theories of gravity. To be concrete, I will focus on the most conservative approach, which is quantum geometrodynamics. It turns out that spacetime is absent at the most fundamental level and emerges only in an appropriate limit. It is expected that the dynamics of matter can only be understood from a fundamental quantum theory of all interactions.
