Non-Unitarity in Physics: A Philosophical Analysis

在量子理论中，时间的流逝被假定为对称性。这个被称为么正时间演化的假设意味着物理实验是“可重复的”，即在一个时间进行的实验必须得到与在任何其他时间完全相同的实验相同的结果。然而，物理学中关于时间之箭和黑洞信息的两个著名问题，也许可以通过允许非么正演化来解决。这个项目旨在对非单位时间演化进行哲学分析，确定它是否真的可以解决这些问题，并探索其认识论和形而上学的含义。

The passage of time is assumed to be a symmetry in quantum theory. This assumption, called unitary time evolution, implies that physical experimentation is "repeatable" in the sense that an experiment performed at one time must give the same results as the exact same experiment at any other time. However, two famous problems in physics, concerning the arrow of time and black hole information, might be solvable by allowing non-unitary evolution. This project aims to perform a philosophical analysis of non-unitary time evolution, determining whether it can indeed solve these problems, and exploring its epistemological and metaphysical implications.
