Where Could Aliens Be Hiding Technology in Our Solar System?

Possibilities include the Oort Cloud and Lagrange points, where NASA can park spacecraft to reduce fuel consumption

Debrief looked recently at five places for hiding “technosignatures.” Technosignatures are evidence of the activity of intelligent agents, as opposed to events or materials that the laws of nature alone can explain. They might include “radio signals, city lights, atmospheric changes like CO2, and free-floating spacecraft.” Or, reaching back into the past, they might be engravings on bone from 51,000 years ago or a child’s burial from 80,000 years ago. Technosignatures are events and entities that nature did not simply generate without some form of thought as a necessary ingredient. If we assume that extraterrestrials want to surveil without being noticed, here’s one of the five venues they might pick — a Lagrange point: Lagrange points are stable places in…
