摘　　要：真相时代科学的典范--广义相对论和量子力学--关于时空的观念存在冲突,在试图结合广义相对论与量子力学的量子引力理论构建中,最关键也最为困难的就是对时空的处理。文章沿着时空观念在物理学理论中的流变,着重分析了量子引力理论中所蕴含的时空观念,揭示了量子引力理论中时空的涌现特性,探讨了其后真相的意义之所在。The notion of spacetime in general relativity and quantum mechanics, which are two exemplars in truth age of science, contradict to each other. This contradiction is both the most important and the most difficult problem in theoretical construction of quantum gravity. Following the development of the notion of spacetime in physical theories, this article analyzes the notion of spacetime in quantum gravity, demonstrates its emergence feature and discusses its post-truth meaning.
