Here’s a case in point on radical uncertainty. Do we believe this? Are we alone? The question is worthy of serious scientific study https://bit.ly/2yQJCNb Declassified information from covert studies is interesting, but not scientifically helpful. This is a topic worthy of open scientific inquiry, until there is a scientific consensus based on evidence rather than prior expectation or belief. If there are indeed extraterrestrial craft visiting Earth, it would greatly benefit us to know about them, their nature and their intent. Moreover, this would present a great opportunity for mankind, promising to expand and advance our knowledge and technology, as well as reshaping our understanding of our place in the universe.  What Happened to the Aliens? https://bit.ly/2KDEX5W We May Be All Alone in the Known Universe, a New Oxford Study Suggests https://for.tn/2Kuh8ho Our main result is to show that proper treatment of scientific uncertainties dissolves the Fermi paradox by showing that it is not at all unlikely ex ante for us to be alone in the Milky Way, or in the observable universe. Our second result is to show that, taking account of observational bounds on the prevalence of other civilizations, our updated probabilities suggest that there is a substantial probability that we are alone.
