Somewhere in some other planet, orbiting some very distant star, maybe in a another galaxy, there could well be entities that are at least as intelligent as we are, and are interested in science. It's not impossible; I think there probably are lots.
假设在遥远的星系的一颗行星上 也许在另一个银河系 存在着至少和我们一样聪明的智慧生物 他们同样对科学感兴趣。这并不是不可能的。我想也许存在很多这样的星球。
