您是否听说过费米悖论？如果没有，这基本上是外国人存在的高统计概率与我们与他们缺乏联系之间的矛盾。

Summed up: It's extremely likely aliens are somewhere, so why haven't we encountered them?

Here are 11 potential answers to the Fermi paradox. Vote on each one and discuss what YOU believe in the comments.

Columbia Pictures

1.Humans aren't capable of receiving the type of signals alien civilizations have sent us.

Paramount Pictures

想象一下，试图通过打电话给传真机或将文本发送到座机来与某人联系。外星人可能会在这一刻发出信号。我们只是无法理解他们。

2.Aliens are quietly observing us like zoo animals.

Universal Pictures

Highly advanced beings are studying us from afar (or maybe even visiting) but not engaging in interaction. There are many reasons why they might choose only to observe, whether it’s because they’re waiting for our civilization to meet particular criteria or they simply want to observe us in our natural habitat without knowledge of their existence.

3.Humans and other intelligent beings are waiting for incoming contact instead of reaching out to make contact.

Paramount Pictures

Imagine seven people scattered across Earth's continents. Each of them has a cellphone that they could use to try to contact each other, but instead of dialing different combinations in the hopes of making contact, they just keep an eye on their respective phones, waiting for an incoming call from someone else.

4.Intelligent civilizations' life spans are so short (compared to the age of the universe) that they don't overlap.

Warner Bros. Pictures

Reddit user matchstiq summed this theory up best: "The time span between when a civilization becomes capable of transmitting radio frequencies and when that civilization annihilates itself is so short that we seldom overlap."

人类只是discovered radio waves in the 1880s, so maybe we'll learn interstellar travel sooner or later and annihilate ourselves through war or some sort of technological accident shortly thereafter, leaving the next intelligent civilization to wonder where everyone's at.

5.Aliens exist but they’ve made themselves undetectable.

Perhaps it's to avoid potential danger if they're discovered. Maybe there are vicious predators lurking throughout the universe and advanced beings don’t want to be found by them.

6.We’re living in a simulation, so our reality is whatever the programmers decide it to be.

Warner Bros.

也许一些更高的生物创建了一个模拟，我们是其中的一部分。也许是出于研究目的而制作的虚拟现实，或者它是一种模拟的天文馆。无论哪种方式，如果创作者不编码外星人，我们将永远不会遇到。

7.还有其他聪明的生活，但非常非常罕见。

生活只有在特殊的，不可能的情况下才能发生，因此聪明的生物在那里，但是它们很不常见，以至于我们极不可能越过道路。

8.Or life is so rare that no other intelligent beings exist. It's just us.

Somehow humans being in the universe alone isn’t any less disturbing than the other possibilities. It might not be as exciting as other theories, yet it manages to be just as existentially troubling.

9.Advanced beings learned how to upload their consciousness to a simulated universe, so they’re too busy enjoying that to spend time interstellar traveling.

Warner Bros.

AsKurzgesagt出色地解释了，“ Matrioshka大脑”是理论上的“围绕星星的巨型结构”。它具有足够的计算机功率，可以让整个物种“上传它们的意识并存在于模拟宇宙中”。这意味着人们可能会体验“纯粹的狂喜的永恒，而不会感到无聊或悲伤”。如果已经实现了这种技术，那么外星人肯定不会在空间寻找其他技术周围巡游。

10。Alien existence has already been confirmed, but the general public is unaware.

Matador Records / Gregory Crewdson

Plenty of folks claim to have seen or to have been abducted by aliens, but they’re not taken seriously. What if governments know of aliens but are withholding information from the masses? Surely there’s a concern that announcing their existence would lead to some sort of global hysteria, so maybe those atop the chain of command choose to keep aliens a secret.

11.Advanced beings are so far ahead of us that they see us as a primitive species, the same way we look at insects.

20th Century Fox

尼尔·德格拉斯·泰森（Neil Degrasse Tyson）将其与人类观看黑猩猩的方式进行了比较。他说，人类和黑猩猩的股份相同98％，但我们比他们更聪明。人类创造艺术并开发技术，但是黑猩猩不能，尽管只有一小部分不同。那么，如果有来自黑猩猩的方式与我们的外星人1％不同，该怎么办？

迪格拉斯·泰森（Degrasse Tyson）说：“我们会流口水，在他们面前充满白痴。”如果一个试图与人交谈的高级外星物种就像人类试图与黑猩猩，鸟或蠕虫进行对话，那么可以解释为什么我们没有遇到它们。
