　　Many science-fictional ideas from the past have subsequently became scientific realities. Take space exploration, for example. In the 1950s this was just a fantastical idea that few people would have dreamt could actually happen. Now it's such a part of modern life that the latest blastoff of a spacecraft, or the discovery of a new planet often doesn't even make the national news.

　　以前科學小說中提出的很多想法已經變成了科學的現實。拿太空探險來說，50年代，這只不過是一種科學狂想，很少人相信有一天會變成現實。可是現在它已成為現代生活的一個組成部分，以至于一次最新的宇航器發射或者一個新行星的發現已不再列為國內新聞。

　　You cannot change the laws of physics ... but could physics actually enable us to travel through time? It might sound crazy, but according to Einstein's theories, there's no logical reason why time travel isn't possible and there are now scientists looking into it as a serious scientific proposal, at least at a theoretical level.

　　你無法改變物理學定律……但是物理學能否使我們在時間中旅行呢?這聽上去或許像個癡想。但是根據愛因斯坦的理論，時間旅行在邏輯上不是不可能的。現在科學家正把它視為一個嚴肅的科學命題，至少在理論上如此。
