CHAPTER 10 WORMHOLES AND TIME TRAVEL
第十章 虫洞和时间旅行
The last chapter discussed why we see time go forward: why disorder increases and why we remember the past but not the future. Time was treated as if it were a straight railway line on which one could only go one way or the other.
我们在上一章讨论了，为什么我们看到时间向前进；为什么无序度增加并且我们记住过去而不是将来。时间好像是一条笔直的铁轨，人们只能往一个方向前进。
But what if the railway line had loops and branches so that a train could keep going forward but come back to a station it had already passed? In other words, might it be possible for someone to travel into the future or the past?
如果该铁轨有环圈以及分叉，使得一直往前开动的火车却返回原先通过的车站，这是怎么回事呢？换言之，人们可能旅行到未来或过去吗？，
H. G. Wells in The Time Machine explored these possibilities as have countless other writers of science fiction. Yet many of the ideas of science fiction, like submarines and travel to the moon, have become matters of science fact. So what are the prospects for time travel?
H·G·韦尔斯在《时间机器》中探讨了这些可能性，正好像其他无数的科学幻想作家那样。科学幻想的许多观念，如潜水艇以及飞往月亮等等都被科学实现了。那么，时间旅行的前景如何呢？
The first indication that the laws of physics might really allow people to travel in time came in 1949 when Kurt Godel discovered a new space-time allowed by general relativity. Godel was a mathematician who was famous for proving that it is impossible to prove all true statements, even if you limit yourself to trying to prove all the true statements in a subject as apparently cut and dried as arithmetic. Like the uncertainty principle, Godel’s incompleteness theorem may be a fundamental limitation on our ability to understand and predict the universe, but so far at least it hasn’t seemed to be an obstacle in our search for a complete unified theory.
1949年库尔特·哥德尔发现了广义相对论允许的新的时空。这首次表明物理学定律的确允许人们在时间里旅行。哥德尔是一名数学家，他因证明了不完备性定理而名震天下。该定理是说，不可能证明所有真的陈述，哪怕你把自己限制去证明在像算术这么一目了然而且枯燥的学科中所有真的陈述。这个定理也许是我们理解和预言宇宙能力的基本极限，然而迄今它还未成为我们寻求完整统一理论的障碍。
