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