Even if they destroy them within say a thousand years, then at any given time there would be only few civilizations at the right age to be broadcasting. And not very loud at that.
We listen only to a miniscule portion of the Galaxy. IMO, Fermi's question shouldn't be "Why can't we hear the few civs that are close to our level".
It should be "How come we don't detect Kardashev >2 civs collonizing most of the galaxy?" Why can't we detect a single Dyson Sphere?
(I don't consider dark forest explanation to be probable though.)
- marcosdumay 5y agoThe Fermi question is a lot closer to "how come Earth wasn't colonized before we even appear?" than "how come we can't see anybody?".
- yreg 5y agoYes, that's a cleaner way to put it.
- mokus 5y agoHow do we know we aren’t the colonists?
- yreg 5y agoThat doesn't solve the paradox though, unless we are quaranteened in a Zoo.
- marcosdumay 5y agoYou mean how we know the Earth wasn't seeded with something similar to archeo-bacteria on purpose? We don't but that doesn't solve the problem. Or how do we know that we, humans, aren't the colonists? Well, all the life we know comes from the same ancestry, including us.
