If Loud Aliens Explain Human Earliness, Quiet Aliens Are Also Rare
- aaroninsf 5y agoFor all their math, these studies persist in fundamental errors of assumption so basic (and IMO obvious) as to make me suspect they are long con gag. TL;DR the presumption that any other civilization would be detectable by us, particularly one substantially more technologically advanced, is... pretty ludicrous. The only interesting exception is civilizations with a specific interest (and capability) to advertise themselves specifically to a civilization at our stage of development. Here's a lemma to Clarke's: any sufficiently advanced communications technique is undetectable, or indistinguishable from noise.
