　　If it were possible, however, it would present some pretty knotty paradoxes... For example, what if someone or something traveled back in time and changed the ensuing future? And have you heard the one about the time traveler who dots back and forward in time and by means of various medical technologies is able to be his own father AND mother?! And besides, if time travel is possible, where are all the people from the future--surely they'd want to come and meet us poor stranded 21st century beings?
　　然而，如果這一切成為可能的話，那么將會出現一些非常令人困惑的邏輯混亂……比如，如果某人或某物逆時間旅行并改變隨之發(fā)生的情況，那會發(fā)生什么情況呢?又比如說，你是否曾聽說過這樣的事情——一位時間旅行者在時間隧道中穿梭往返，利用各種醫(yī)學技術使自己成為自己的父親和母親?還有，如果時間旅行成為可能，未來的所有人都會在哪里呢?他們肯定想來見見我們這些滯留在21世紀的可憐人。

　　The experiment was replicated in 1996 with advanced technology, and it was proved again--with an even bigger time difference this time. Which proves that not only is time “warp-able”, but Einstein was arguably the greatest thinker the world has ever seen. So, time is warped--and this opens up the possibility that we might be able to somehow manipulate it as a mode of travel one day. Already one scientist has published a paper in which he detailed how to build a time machine.
　　1996年，科學家用先進的技術重復了同樣的實驗，也證實了該理論，時間差距甚至更大了。這一實驗不僅驗證了時間的可扭曲性，還證明愛因斯坦可能是人類史上最偉大的思想家。所以說，時間是可彎曲的。這也使我們或許有朝一日有可能利用它作為某種形式進行旅行。有一位科學家已經發(fā)表了一篇論文，詳細地描述如何建造一部時間機器。
