“What is the nature of time? Will it ever come to an end? Breakthroughs in physics, made possible in part by fantastic new technologies, suggest answers to some of these longstanding questions. Someday these answers may seem obvious to us as the earth orbiting the sun—or perhaps as ridiculous as a tower of tortoises. Only time (whatever it may be) will tell”.
时间的本质是什么？ 它会有一个终结吗？ 物理学中最近的突破， 使我们有可能为其中一些长期以来悬而未决的问题提供答案， 而奇妙的新技术是实现这些突破的部分原因。 对我们而言， 这些答案也许有朝一日会变得和地球围绕着太阳公转那么显而易见——或许也会变得和乌龟塔一样荒谬， 只有时间（不管其含义如何） 才能裁决。
