外星人在哪里？
宇宙应该充满了外星人
纳瓦尔： 让我们简单谈谈费米悖论，因为我们谈论的是外星人。对于不知道的听众来说，介绍一下：恩里科·费米是一位著名的物理学家，曾参与曼哈顿计划，他说：“外星人在哪里”？
宇宙如此之大，可能有很多不同行星能够支持某种或另一种生命，我们不是应该看到它们才对吗？
布雷特： 几乎每颗恒星周围都有一群行星，很像我们的太阳系。像银河系这样的典型星系中存在的恒星数量大约是 2000 亿颗，尽管估计高达 4000 亿颗左右，我们可以看到的星星数量约为 2000 到 3000 亿。
可观测的宇宙只是整个宇宙的一小部分，这意味着行星的数量绝对是天文数字。
当然，鉴于这些数字，不仅有适合生命存在的行星，而且宇宙中应该充满比我们先进得多的文明、或落后于我们的文明，还有一些文明与我们相似。
那么他们在哪里呢？
Nov 1 2021Where Are the Aliens?The universe should be teeming with aliens
Naval: Let’s talk briefly about theFermi paradox since we’re talking about aliens. For listeners who don’t know,Enrico Fermi was a famous physicist who was part of the Manhattan Project. He said, “Where are the aliens?”
The universe is so large and there are probably so many planets that are capable of supporting life of some kind or another. Shouldn’t we have seen them by now?
Brett: Around almost every star there is a contingent of planets much like our own solar system. The number of stars that exist within a typical galaxy like the Milky Way is something like 200 billion, although the estimates go up to about 400 billion. The number of galaxies that we can see is around 200 to 300 billion.
The observable universe is just a small fraction of the entire universe, which means that the number of planets is absolutely astronomical.
Surely, given these numbers, it has to be the case that there are not only planets out there that are suitable for life but that the universe should be teeming with civilizations far more advanced than ours, less advanced than ours, and some that are similar in advancement to ours.
So where are they?
马丽：一花一世界，一叶一菩提。宇宙很大。在宇宙中，太阳系或者地球，相当于宇宙中的一只蚂蚁、一颗尘埃，人类就是宇宙的一个单细胞、蛋白质、甚至只是某个氨基酸。so,地球只是宇宙搭建的千千万万积木场之一，并被赋予了风雨雷电、山川河流、喜怒哀乐、爱恨情仇，让人类玩耍起来更有体验感，它被设定了一些初始设置、游戏（自然）规则、天道，但宇宙并没有给地球边框，人类小伙伴们可以尽情蹦跶、折腾，来享受这个无限的地球&星际游乐场。
