U.S. Navy drafting new guidelines for reporting UFOs
People seem to break it down into three potential categories: misinterpretted&#x2F;bad data&#x2F;not real, secret project carried out by other nation, or extraterrestrial craft.<p>Extraterrestrial doesn&#x27;t make sense, because of the difficulty in crossing interstellar distances. But in the case of really solid evidence, eg the Nimitz incident, neither of the first two categories really make sense either.<p>I think there&#x27;s a fourth category that people aren&#x27;t considering: Von Neumann probes which self-replicated in-situ and are performing scouting &#x2F; intelligence gathering. When people consider Von Neumann probes independently, there&#x27;s always the question of, why don&#x27;t we see any around? Given even modest rates of travel and self replication, they should be at every star system in the galaxy, if any were ever created.<p>Well, maybe they are around, and we have seen them.
