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(xué)小說中提出的很多想法已經(jīng)變成了科學(xué)的現(xiàn)實。拿太空探險來說,50年代,這只不過是一種科學(xué)狂想,很少人相信有一天會變成現(xiàn)實?墒乾F(xiàn)在它已成為現(xiàn)代生活的一個組成部分,以至于一次較新的宇航器發(fā)射或者一個新行星的發(fā)現(xiàn)已不再列為國內(nèi)新聞。
