论文摘要
由于观察或相互作用,Infinity的出现以及量子状态的崩溃状态,这是量子场理论的两个具有挑战性的特征,在量子重力以及时空的量子几何形状中成为非常严重的问题。这些问题可以分为两类:技术和概念部分。在技术方面,最大的问题来自构造经典几何形状的点的定义。通过更改点的定义,可以大致绕过技术问题,并可以找到量子几何形状的数学表述。另一方面,概念问题来自由于观察到的观察而导致的量子状态崩溃,因为观察者和重力之间的纠缠无法在存在的情况下消除。概念部分不取决于所采用的技术。我们尽可能地尝试通过重新发现对量子理论观察者的现象的看法和理解来讨论这些问题。
The appearance of infinity together with collapsing quantum state due to the observation or interaction, which are two challenging features of quantum field theory, become very serious problems in quantum gravity as well as in quantum geometry of space-time. These problems can be divided into two categories: technical and conceptual parts. In the technical aspect, the biggest problem comes from the definition of the point, which constructs classical geometry. By changing the point definition, the technical problem may be approximately bypassed, and a mathematical formulation of quantum geometry may be found. On the other hand, the conceptual problem comes from the quantum state collapse due to the observation since the entanglement between the observer and gravity cannot be eliminated in the presence of gravity. The conceptual part does not depend on the techniques which are employed. As much as possible, we try to discuss these problems by rediscovering the perception and understanding of a phenomenon for an observer in quantum theory.
