Shermer and Powell discuss: • technosignatures and biosignatures • convergent vs. contingent evolution • SETI science vs. UFO/UAP science • Are they out there? 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…

Robert Powell — UFOs: What We Know (And Don’t Know)
Lisa Kaltenegger — The New Science of Planet Hunting in the Cosmos
Shermer and Kaltenegger discuss: Carl Sagan and his influence • Sagan’s Dragon • ECREE Principle • how stars, planets and solar systems form • how exoplanets are discovered • Hubble Space Telescope, Kepler Space Telescope, James Webb Space Telescope • The Origin of Life • Fermi’s Paradox: where is everybody (the Great Silence, the Great Filter) • biosignatures • technosignatures • Dyson spheres • Will aliens be biological or AI? • interstellar travel • Kardashev scale of civilizations • how…
Visits to and From Extraterrestrials: Why They Never Occurred, and Probably Never Will
Despite much ballyhoo in the media, all efforts thus far have failed to provide substantive evidence that might link the appearance of UFOs, now called UAPs (unidentified aerial phenomena), with aliens from other planets. This failure results from limitations imposed by both biology and distance. As Morton Tavel explains, when these factors are combined, they render any such contacts virtually impossible.
eSkeptic for July 13, 2021
From teleportation and space elevators to alien contact and interstellar travel, science fiction and fantasy writers have come up with some brilliant and innovative ideas. Yet how plausible are these ideas? In this lecture from our archives, recorded in February 2014 as part of The Skeptics Society’s Distinguished Science Lecture Series, professor of physics, Dr. Charles Adler, delves into the most extraordinary details in science fiction and fantasy.
eSkeptic for February 28, 2018
In this week’s eSkeptic, Harriet Hall, M.D. (aka The SkepDoc) examines many of the health benefit claims for juicing, and finds them lacking scientific scrutiny.
Dr. Kip Thorne — Gravitational Waves, Black Holes, Time Travel, and Hollywood
Nobel Prize winner Dr. Kip Thorne will reflect on his life and career in theoretical physics, his work on gravitational waves, black holes, wormholes, and time travel, his relationship and bet with Stephen Hawking, and how he came to consult on Carl Sagan’s Contact and Christopher Nolan’s Interstellar.
Wizards, Aliens, and Starships: Physics and Math in Fantasy and Science Fiction
From teleportation and space elevators to alien contact and interstellar travel, science fiction and fantasy writers have come up with some brilliant and innovative ideas.

In Skeptic magazine 17.3, Michael Gainer wrote “The Physics of UFOs” in which he sought to determine if it is possible to construct an interstellar spacecraft that fits the description of reported UFOs. In response to that long-time skeptic, Peter Huston penned a skeptical analysis entitled, “Another Physics of UFOs.” We published both articles in last week’s eSkeptic. In this week’s eSkeptic, Gainer responds to Huston.

In this week’s eSkeptic, we present an article by Michael K. Gainer (from Skeptic magazine 17.3) about the feasibility of interstellar travel, followed by a rebuttal from Peter Huston.
