Space-Time as a Physical System
We feel ourselves localized in space and lasting in time, and, in the last analysis, almost all schemes of modern physics describe events that are happening in the arena of space-time. However, since the time of the creation of general relativity theory and quantum mechanics, there has been an increasing tendency to consider space-time as a physical system in its own right. The principles for describing space-time still remain classical. The difficulties of quantum field theory apparently point to a contradiction between these principles and universal quantum laws.
