茫茫字宙,地球人是不是唯一的智慧生命?这个问题我们从小问到老,答案从来都是模糊的。不过,以撰写《时间简史》而被我们熟知的英国物理学家霍金却在最近明确地警告人们:外星生命几乎肯定存在,但是我们最好不要轻易和他们打招呼。霍金认为:假如外星人有朝一日来到地球,就会和哥伦布到达美洲大陆时的情景差不多。他们会为了掠夺资源而大举入侵,然后扬长而去。所以为了保护自己,地球人轻易不要寻找他们,更不要主动和他们打招呼。总而言之就是一句话:外星人你伤不起!好莱坞似乎比霍金更早就意识到了这种可能性,所以在科幻电影诞生以来,像E.T.那样带着善意来到地球的外星人屈指可数。直到今天,电影中的外星人也多数都是来势汹汹,到了地球二话不说就开始实行种族灭绝的太空蝗虫。
Boundless universe, the earth is not the only wise life? This question we asked from an early age, the answer has always been vague. However, Hawking, the British physicist well-known to us for writing A Brief History of Time, recently explicitly warned people that alien life is almost certain, but we’d better not say hello to them easily. Hawking believes that if aliens would someday come to Earth, it would be similar to when Columbus arrived on the American continent. They will invade the massive invasion of resources, and then go away. Therefore, in order to protect themselves, the Earth people do not easily find them, let alone take the initiative to greet them. All in all, the sentence is alien: you can not afford to hurt! Hollywood seems to be aware of this possibility earlier than Hawking, so since the birth of science fiction movies, there are only a handful of aliens who came to Earth with goodwill like ET . Even today, most of the aliens in the movie are menacing, and as soon as the Earth goes to a standstill, they have begun to carry out genocidal space locusts.
