Could Alien Probes Already Be Here? With John Gertz

from John Michael Godier's Event Horizon · host John Michael Godier

Could alien probes already be watching us from inside our own solar system? John Michael Godier speaks with John Gertz, former chairman of the SETI Institute, about why extraterrestrial civilizations may send robotic probes rather than radio signals, and whether such objects could already be hidden among asteroids, orbiting the Sun, or even closer to Earth.The discussion explores Gertz’s new book Reinventing SETI, his critiques of the Fermi Paradox and von Neumann probes, the risks of METI, and the possibility that life on Earth itself may have been seeded through intentional panspermia.Reinventing SETI: New Directions in the Search for Extraterrestrial Intelligenceby John Gertzhttps://a.co/d/2xBJ5JpJohn Gertz links: https://linktr.ee/astrogertzhttps://www.youtube.com/@johngertz652800:00 Intro — John Michael Godier welcomes John Gertz00:19 Gertz’s background and SETI involvement02:05 Breakthrough Listen and SETI funding history04:40 Why NASA should fund SETI06:51 Microbes vs intelligent life09:01 Flaws in the Fermi Paradox framing11:02 Von Neumann probes and galactic law13:50 Are probes already here in the Solar System?17:05 The Great Silence and surveillance probes20:19 Galactic internet, redundancy, and data storage22:32 Reinventing SETI — Gertz’s new book24:27 UFOs, UAPs, and evidence standards27:02 Skepticism, the press, and missing radar data31:58 Could probes operate in Earth’s atmosphere?33:54 Why we lack dashcam UFOs vs meteor footage35:20 The best time to search for technosignatures36:01 Archival plate anomalies (Villarroel’s work)38:22 Satellite anomalies and Trojan co-orbitals40:11 Could asteroids hide alien probes?42:10 Where to search for probes in the Solar System44:58 Rogue planets and white dwarfs as SETI targets46:59 Panspermia and intentional seeding of life49:59 Abiogenesis experiments and early Earth life50:53 Microbial life as ubiquitous, intelligence as rare52:26 Dinosaurs, raccoons, and evolutionary contingencies55:11 The next generation of SETI researchers57:19 Will we crack abiogenesis within 20 years?59:03 NASA budgets, telescopes, and future risks60:11 Outro — thanks and closing remarksYouTube Membership: https://www.youtube.com/channel/UCz3qvETKooktNgCvvheuQDw/joinPodcast: hhttps://creators.spotify.com/pod/show/john-michael-godier/subscribeApple: https://apple.co/3CS7rjTMore JMG https://www.youtube.com/c/JohnMichaelGodierWant to support the channel?Patreon: https://www.patreon.com/EventHorizonShowFollow us at other places!@JMGEventHorizonMusic:https://stellardrone.bandcamp.com/https://migueljohnson.bandcamp.com/https://leerosevere.bandcamp.com/https://aeriumambient.bandcamp.com/FOOTAGE:NASAESA/HubbleESO - M.KornmesserESO - L.CalcadaESO - Jose Francisco Salgado (josefrancisco.org)NAOJUniversity of WarwickGoddard Visualization StudioLangley Research CenterPixabay
