我们不知道的时间
What we don't know about time
摘要：
弦论改变了我们对几何、拓扑和时空的理解。因此，对于这期纪念“弦论四十年“的《物理学基础》特刊，退一步问一问我们不理解的东西似乎是合适的。正如我将要讨论的，时间仍然是物理理论中最不被理解的概念。虽然我们在理解空间方面取得了重大进展，但我们对时间的理解并没有超过一个世纪前爱因斯坦提出时空是一个组合实体的想法时的水平。因此，我将提出一系列关于时间的开放性问题，并将回顾已取得的一些进展，作为未来的路线图。
英文摘要：
String theory has transformed our understanding of geometry, topology and spacetime. Thus, for this special issue of Foundations of Physics commemorating "Forty Years of String Theory", it seems appropriate to step back and ask what we do not understand. As I will discuss, time remains the least understood concept in physical theory. While we have made significant progress in understanding space, our understanding of time has not progressed much beyond the level of a century ago when Einstein introduced the idea of space-time as a combined entity. Thus, I will raise a series of open questions about time, and will review some of the progress that has been made as a roadmap for the future.
