When talking about the Fermi Paradox it's not about what this or that extra-terrestrial civilization might do. It's about what none of them is doing.
When you say "maybe they don't want to expand", if you want this to explain the paradox, you actually mean "none of them want to expand". Because if just one did, we would see it.
- gmuslera 8y agoIs not "none of them" but "all the ones that reached certain knowledge level", after you know something, you avoid expanding or showing yourself. The dark forest idea comes from Liu Cixin Three Body Problem trilogy, if you show yourself you risk being destroyed by even more powerful civilizations that are hidden in the dark. And they are hidden because are afraid that the same happens to them, with a third one or with the one they destroyed after they advanced enough. It is not the only possible reason, just one of the possible things that we don't know (or even don't know that we don't know) that can disprove or at least atenuate enough the paradox hypothesis. Can be like explaining a caveman why you can't make a building high enough to reach the moon, so far he knows would be doable and even desirable for us, so why we didn't built one yet?
- posterboy 8y agoWe would see it? Do you have any idea how big the universe is, and how little we see? If there were astronauts on pluto right now, we could not detect them, I suppose -- I might be wrong, but the statement is bound to be true at some order of magnitude that's certainly smaller than the theoretically visible universe.
