The '''arrow of time''', also called '''time's arrow''', is the concept positing the "one-way direction" or "asymmetry" of [[time]]. It was developed in 1927 by the British astrophysicist [[Arthur Eddington]], and is an [[List of unsolved problems in physics|unsolved general physics question]]. This direction, according to Eddington, could be determined by studying the organization of [[atom]]s, [[molecule]]s, and bodies, and might be drawn upon a [[Four-dimensional space|four-dimensional]] relativistic map of the world ("a solid block of paper").<ref>{{cite book

'''<font color="#ff8000"> 时间之箭The arrow of time</font>'''，是一种概念，假定时间是“单向方向”或“不对称”的。此概念于1927年由英国天体物理学家亚瑟·爱丁顿提出的一个普通物理学问题，至今尚未解决。按照爱丁顿的说法，研究原子、分子和物体的组织可以确定时间的方向，也可以绘制在一张四维的相对论世界地图上(“一整块纸”)。

Physical processes at the microscopic level are believed to be either entirely or mostly time-symmetric: if the direction of time were to reverse, the theoretical statements that describe them would remain true. Yet at the macroscopic level it often appears that this is not the case: there is an obvious direction (or flow) of time.

人们通常认为，微观层面上的物理过程认为是全部或部分时间对称的: 如果时间的方向逆转，描述它们的理论仍然正确。然而，在宏观层面上，情况往往并非如此， 时间存在明显的方向(或流动)。
