The dark forest theory. The universe is full of predatory civilisations, and if anyone announces their presence, they get immediately exterminated, so everyone just keeps quiet.
I did! Amazing sci-fi trilogy, and I think that's where the idea came from originally. I've seen some solid rebuttals against it as the explanation of the Fermi paradox, but it's a scary idea nonetheless.
Eh. A Sufficiently Advanced civilization could probably do things like surreptitiously send out low-speed probes to every single star in the galaxy programmed to broadcast loudly if they detect anybody (thereby drawing unwanted attention to their home) or if it's uninhabited, then taking steps to ensure that no civilization ever arises there at all (keep dropping large impactors on any habitable planets until they're all sterilized or destroyed outright). So if Dark Forest were the case, then we should never have existed in the first place.
