Continuing to speculate, if 1% of intelligent life survives long enough to become a potentially galaxy-colonizing Type III Civilization, our calculations above suggest that there should be at least 1,000 Type III Civilizations in our galaxy alone—and given the power of such a civilization, their presence would likely be pretty noticeable. And yet, we see nothing, hear nothing, and we’re visited by no one. _FV.}%W<u
继续推测，如果有1%智慧生命能够幸存发展到星系殖民的III型文明，我们上面的计算表明有至少1000种独立的III型文明，一个拥有这么大能量的文明会很容易被察觉。而至今我们还没有看见或听见任何文明信息，也没有来地球造访的文明。 ^Iz.O

We have no answer to the Fermi Paradox—the best we can do is “possible explanations.” And if you ask ten different scientists what their hunch is about the correct one, you’ll get ten different answers. You know when you hear about humans of the past debating whether the Earth was round or if the sun revolved around the Earth or thinking that lightning happened because of Zeus, and they seem so primitive and in the dark? That’s about where we are with this topic. B[$e;h*Aw[
到现在还没有费米悖论的答案，我们能做的只有猜。问10个科学家他们的猜测，你会得到10个不同的答案。知道以前人们争论地球绕着太阳转还是太阳绕着地球转，还有宙斯放的闪电，那时候的人看起来那么原始，就像生活在黑暗中。其实这和费米悖论差不多。 'fB `e]_

In taking a look at some of the most-discussed possible explanations for the Fermi Paradox, let’s divide them into two broad categories—those explanations which assume that there’s no sign of Type II and Type III Civilizations because there are none of them out there, and those which assume they’re out there and we’re not seeing or hearing anything for other reasons. b9U 2afd
关于费米悖论的大部分人认可这些假设（分为两大类）：第一类认为II，III型文明不出来活动，第二类是他们出来活动，我们因为各种原因收不到他们的信息。
