Robert Powell is a founding Board member of the Scientific Coalition for UAP Studies (SCU). He is a member of the Society for Scientific Exploration, the UFODATA project, and the National Space Society.

Have they come here? • what alien intelligence might be like (biological, digital, or otherwise) • Bayesian reasoning about UFOs and UAPs • the U.S. military UAP videos and what they represent • The Disclosure Project from the U.S. government • Projects Sign, Blue Book, Cyclops, Grudge • AATIP (Advanced Aerospace Threat Identification Program) • directionality and teleology in evolution of life • interstellar travel • Dyson spheres, rings, and swarms.
