在宇宙中肯定并非只有我们人类,至少那些喜欢科学幻想的人是这么认为的。同时,在有些科学家看来,这也是一个非常可能的假设。但是,如果有那么一天我们捕捉到智能生命信号、能够证明地外确实有“人”的声音时又当如何?人们在2004年9月就“险些”发现了它。
It is certainly not the only human beings in the universe, at least those who like science fiction think so. At the same time, it is also a very likely assumption for some scientists. But what if one day we caught the signal of a smart life that could prove that there was indeed a “human” voice? People found it “almost” in September 2004.
