2010年11月,适逢“搜索地外文明”项目50周年,人们对外星文明热议再起。鉴于浩瀚宇宙中有很多自然条件与地球相仿的星球,总会有若干星球诞生类似地球生物的生命体,且其中的一部分会进化成拥有高级智慧的生物。因而,科学家普遍认为外星人理应存在。但外星人与人类之间能否取得联系?专家们则意见不一。著名天体物理学家斯蒂芬·霍金认为外星人几乎是肯定存在的,但警告人类不要努力去寻找外星人,应尽量避免与其接触。否则,有可能给人类带来灾难。本文作者也持类似观点。从文学作品到科幻电影,人们展开无尽的想象,伴着莫名的恐惧,由己及人勾画着外星人的形象及其与人类接触的种种可能的情形,但人类的局限性可能也正是以自己的智能推测不同于己的智能生命。
In November 2010, coincides with the 50th anniversary of the project “Searching for Extraterrestrial Civilizations,” people are experiencing a resurgence of extraterrestrial civilization. Since there are many planets in the vast universe with natural conditions that are similar to those of the Earth, there are always a number of planets that give birth to living beings that are similar to Earth’s life, and some of them will evolve into creatures with advanced wisdom. Therefore, scientists generally believe that aliens should exist. But can alien and human be able to get in touch? The experts disagreed. The famous astrophysicist Stephen Hawking believes that aliens are almost certain to exist, but warned humans not to work hard to find aliens, should try to avoid contact with them. Otherwise, it may bring disaster to human beings. The author of this article also hold similar views. From literary works to science fiction movies, people start endless imagination, accompanied by inexplicable fears, and have drawn aliens’ images and their possible contact with human beings, but the limitations of human beings may also precisely My own intelligence is different from my own intelligent life.
