The Dark Forest Theory. Before I explain it, I’ll give a little bit of background information to put it into perspective:

The Dark Forest is one of many theories that may explain the Fermi Paradox. If you aren’t aware, the Fermi Paradox is the apparent contradiction between the lack of evidence and high probability for the existence of extraterrestrial civilizations elsewhere in this vast, unending Universe.
黑暗森林理论是解释费米悖论的众多理论之一。如果你还不知道的话，费米悖论说的就是在这个浩瀚无垠的宇宙中，外星文明存在的高概率与缺乏证据之间的明显矛盾。
There are hundreds of billions of galaxies in the known universe. The Milky Way Galaxy alone has at least 100 Billion stars; each star more or less like our own (which we call the Sun, or “Sol”). Each of these stars potentially has several planets in orbit around them.
在已知的宇宙中有数千亿个星系。仅银河系就有至少1000亿颗恒星；每颗恒星或多或少都与我们自己的恒星(我们称之为太阳)相似。每一颗恒星周围都可能有几颗行星。
Even if only the tiniest fraction of these planets held life, and only the tiniest fraction of life-bearing planets held intelligent life, we are still looking at thousands of extraterrestrial civilizations out there in just the Milky Way Galaxy alone. And that’s not even including the other hundreds of billions of galaxies!
