Where Are the Aliens?

We still don't know. But we have some assumptions, which helps us to think and prepare for some possibilities.

Famously, The Fermi Paradox address this question.

Starry Night

I wonder, when you look at this starry night sky, what does it make you feel?

When Enrico Fermi saw it, he was like: ”Where is everybody?” His wonders are not irrational, because [[The Universe Is Extremely Big]], and when the numbers get extreme, evem the smallest possibilities would result in some pretty big numbers: [[Number of Planets That Possibly Have Life]].

But SETI has never picked up any extraterrestrial signal, ever.

If you think of even with only considering the lowest possibilities of the existence of other life on other planets, there's a great number of planets that might contain life, then if you consider the [[Kardashev scale]] as well, it wouldn't become weird that we've never observed any alien life.

So that's the Fermi Paradox: Where's everybody?

There are some attempted explanations (these are not fact based explanations, they are theories or people's attempts to consider the possible answers). And since they are not science based, they vary a lot. There are mainly opposite 2 sides. The reason we've never found extraterrestrial intelligence is because:

  1. [[There Are No Other Civilizations Out There]]
  2. It Wouldn't Be A Good Idea For Extraterrestrial Civilizations To Contact Us: [[Extraterrestrial Civilizations Don't Want To Contact Us]].
