著名科学家霍金最近警告我们:不要和外星人说话!霍金认为:宇宙有几千亿个星系,而每个星系中又有数亿颗恒星,这么大的宇宙,地球不可能是唯一拥有生命的星球,因此他肯定有外星人存在。然而他告诫我们:外星人到地球上来,有可能像哥伦布到美洲大陆一样,给当地人带来的只能是灾难。因此,我们人类不应努力去寻找外星人,而应该尽量避免与外星人接触。
The famous scientist Hawking warned us recently: Do not talk to aliens! According to Hawking, there are hundreds of billions of galaxies in the universe and hundreds of millions of stars in each galaxy. Earth can not be the only one who owns life in such a big universe Planet, so he must have aliens exist. However, he warned us that if aliens come to Earth, they may be able to bring only a catastrophe to the locals like Columbus to the mainland. Therefore, we humans should not strive to find aliens, but should try to avoid contact with aliens.
