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…

Are the Aliens We Never See Obeying Star Trek’s Prime Directive?

The Directive is, don’t interfere in the evolution of alien societies, even if you have good intentions

Using the Murchison Widefield Array (MWA) telescope, astronomers recently scoured a part of the sky known to contain at least 10 million star systems for evidence of alien technology (“techno signatures”). And the result? “With this dataset, we found no technosignatures — no sign of intelligent life.” Professor Tingay said even though this was the broadest search yet, he was not shocked by the result. “As Douglas Adams noted in The Hitchhikers Guide to the Galaxy, ‘space is big, really big’.” International Centre for Radio Astronomy Research, “Australian telescope finds no signs of alien technology in 10 million star systems” at ScienceDaily The paper is open access. Various sources offer explanations for the absent aliens; the most popular is that…
