Released: 4 February 2021 Duration: 58 minutes 44 seconds Co-hosts Paul Carr and Daniela DePaulis are joined by author Thomas Moynihan. The subject is the idea of human extinction and how it evolved into our present day understand of Existential Risk. Guest Bio: I am a writer and researcher from the UK. In 2019, I completed a PhD at Oriel College on the history of human extinction. Currently, I am a visiting Research Associate in History at St Benet's College, Oxford University, and I am working for Oxford's Future of Humanity Institute with a grant from the Berkeley Existential Risk Initiative.    I am interested in the history of existential risk and of existential hope: that is, how people first came to understand the perils and promises that face us as a species. I see this as the central philosophical drama of the modern world: how we came to appreciate our position—and precarity—as intelligent beings within an otherwise seemingly silent and sterile universe.    My goal is to reveal how contemporary research into global risks can be seen as part of the wider story of our ‘coming of age’ as a civilisation and a species.

Released: 10 February 2019 Duration: 16 Minutes, 51 Seconds   Abraham Loeb and Shmuel Bialy kicked up a kerfuffle when they wrote a paper suggesting that one possible explanation for ‘Oumuamua was that it could be an artificial object, in other words, an alien spacecraft—specifically, a lightsail. The two have been praised for their boldness and condemned for their recklessness, but little has been said concerning the possibility of detecting a lightsail as a technosignature in comparison to detecting a “conventional” technosignature such as the radio and laser beacons that SETI searches for. When we look out into the universe for signs of intelligence, if there are technosignatures to be seen, what technologies ought we to expect to be the most common?      Links Stagnant Supercivilizations and Interstellar Travel “Could Solar Radiation Pressure Explain ‘Oumuamua’s Peculiar Acceleration?” Bialy and Loeb  Predictably, online media go nuts over ‘Oumuamua and Harvard scientists; “Scientists are perfectly happy to publish an outlandish idea.” by Eric Berger Breakthrough Starshot  lightsail (Wikipedia) The Interstellar Age: The Story of the NASA Men and Women Who Flew the Forty-Year Voyager Mission by Jim Bell NASA Voyager 2 Could Be Nearing Interstellar Space The Great Filter—Are We Almost Past It? by Robin Hanson SETI as a Process of Elimination Credits Written and Presented by: Nick Nielsen Postproduction: Paul Carr Music: DJ Spooky   This podcast episode is released under the Creative Commons Attribution/Share-Alike license

Released: 27 May 2016 Duration: 67 minutes, 16 seconds   We interview LSU astronomer Bradley Schaefer about why is sticking to his guns about the century-long dimming of Tabby's Star (KIC 8462952), why some popular explanations fail, and what can be done to further explore the reason that this star's behavior is so behavior. In particular, Brad wants to encourage us to contribute to Tabetha Boyajian's kickstarter to buy telescope time to monitor the star.   Links: The Fast and Slow Dimming of Tabby's Star Tabby's Star for the Perplexed, Part 1 The Most Mysterious Star in the Universe Brad Schaefer: KIC 8462852 Faded at an Average Rate of 0.165+-0.013 Magnitudes Per Century From 1890 To 1989 Brad Schaefer on Centauri Dreams: Further Thoughts on the Dimming of KIC 8462852     Credits: Host and Producer: Paul Carr Announcer: Erin Carr Music: DJ Spooky, George Hrab   The Wow!

Released: 18 May 2016 Durations: 3 minutes, 33 seconds   A short Burst to briefly explain today's development and to ask listeners to seriously consider donating to the new Kickstarter to monitor KIC 8462852 with a network of telescopes using standardized photometry. The hope is that we will reliably catch the star in the act of dimming. Please share this and the link to the kickstarter widely. Together, we can catch Tabby's Star in the act.   Links: The Most Mysterious Star in the Universe Tabby's Star for the Perplexed, Part 1 (Burst 13) Interview With Tabetha Boyajian (Season 3, Episode 4) Interview with Stella Kafka of the AAVSO (Season 3, Episode 5)   Credits: Host and Producer: Paul Carr Music: Jason Robinson Postprocessing: Auphonic.com Hosting: Libsyn.com   The Wow!

Released: 6 April 2016 Duration: 43 minutes, 45 seconds Thread: Astronomy and Astrophysics   In Tabbys' Star for the Perplexed Part 1, we explained why this is puzzling star. In Part 2, we talked about some of the explanations put forth and their weaknesses. In the third and last (for now) part of the series, we talk to Tabby herself, and she answers several reasonably informed questions about her team's work, past, present and future.

In this part we talk about some of the candidate explanations, including alien megastructures, including a Dyson Swarm.   Links Please see wowsignalpodcast.com The Slow and Fast Dimming of Tabby's Star AstroWright   Credits: Written, Produced, and Voiced by Paul Carr Music: Jason Robinson  

Released: 16 March 2016 Duration: 13 minutes, 25 seconds   Science does not occur in a vacuum, and this is doubly true in the case of SETI, which is said to suffer from a "giggle factor." How does social context shape the scientific research program of SETI? The public at times shows great interest in SETI, but this attention can cut two ways, both benefiting and harming the discipline. Nowhere is this more true than in funding for SETI research.   Credits: Written and Read by: Nick Nielsen Producer and VO: Paul Carr Music: Jason Robinson

Released: 10 March 2016 Duration: 18 minutes, 1 second   In Part 1, Paul Carr provides a non-technical explanation of why the star informally known as Tabby's Star (KIC 8462852) is so perplexing after all. What was observed, and why doesn't it fit a conventional explanation?

Released: 13 February 2016 Duration:20 minutes, 35 seconds   Nick Nielsens's show notes: In so far as SETI is a science -- and it aspires to be a science even as its critics argue that it falls short -- should its emphasis fall upon confirmation or disconfirmation? I argue that the falsification of narrowly formulated hypotheses about exocivilizations can both demonstrate the scientificity of SETI as well as refine our conception of exocivilizations, hence refining our idea of the exact nature of the object of our search.     The origin of this Wow! Signal Burst (now revised and updated so that little remains of the original except the central idea) is a blog post that I wrote some time ago, SETI as a Process of Elimination, which was part of a series of posts about SETI, including Methodological Naturalism and the Eerie Silence, Why the Fermi Paradox Must be Taken Seriously, Addendum on the Fermi Paradox,  The Visibility Presumption, and Searching the Sky.   Credits Written and Read by: Nick Nielsen Producer and VO: Paul Carr Music: Jason Robinson

Released: 6 February 2016 Duration: 22 minutes, 18 seconds An edited interview with Dr. Josh Grindlay concerning the use of measurements of star brightness from the Digital Access to a Sky Century @HArvard to measure the dimming (or not) of Tabby's Star over a Century. Grandly critiques Hippke's paper that found dimming in several stars in the DASCH data, and also Schaefer's claim that Tabby's Star (KIC 8462852) is slowly dimming.   Links: Boyajian, et. al. Planet Hunters X.
