In the debate about the direction of time in physics, the concept of time reversal has been central. Tradition has it that time-reversal invariant laws are sufficient to state that the direction of time is non-fundamental or emergent. In this paper, we review some of the debates that have gravitated around the concept of time reversal and its relation to the direction of time. We also clarify some of the central concepts involved, showing that the very concept of time reversal is more complex than frequently thought.
在关于物理学中时间方向的辩论中,时间反演的概念一直处于核心地位。传统观点认为,时间反演不变的定律足以表明时间的方向并非基本的或涌现的。在本文中,我们回顾了一些围绕时间反演概念及其与时间方向的关系展开的辩论。我们还澄清了一些涉及的核心概念,表明时间反演这一概念本身比通常认为的更为复杂。
