On the likelihood of non-terrestrial artifacts in the Solar System

摘要: Abstract Extraterrestrial technology may exist in the Solar System without our knowledge. This is because vastness of space, combined with limited searches to date, implies that any remote unpiloted exploratory probes extraterrestrial origin would likely remain unnoticed. Here we develop a probabilistic approach quantify certainty (or uncertainty) existence such System. We discuss some possible strategies for improving this uncertainty include analysis moon- and Mars-orbiting satellite data as well continued exploration
