论当代量子引力的空间时间观念

On the Ideas of Space and Time in Contemporary Quantum Gravity

首先讨论当代诸种量子引力,如超弦/M理论、圈量子引力等,继而研究空间时间量子涨落对量子引力理论的经验检验,最后讨论了有关量子引力时空的物理实在问题.

First, the properties of space and time in contemporary quantum gravity are discussed, i.e. superstring/M theory, loop quantum gravity. Second, this paper studies the quantum fluectuation of spaectime. Last, some problems of physical reality on the space and time are given.
