Episode 49 - Existential Risk


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:

Thomas Moynihan

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.

Guest Bio

Paola Costaño
Paola Castaño is a sociologist of science. She recently completed a Newton International Fellow funded by The British Academy at Cardiff University and is working on a book about the meanings and valuations of scientific research on the International Space Station. On the basis of ethnographic work following the life course of experiments sent to the station, the book examines the fields of particle physics, plant biology and biomedical research. She has a PhD in sociology from the University of Chicago, and has been a postdoctoral researcher at the Smithsonian Air and Space Museum in Washington DC, the Free University of Berlin, and Waseda University in Tokyo.

Burst 31 Beyond the SETI Paradigm



Released: 6 February 2019
Duration: 16 Minutes, 51 Seconds

Download the .mp3 audio file

Avi Loeb
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?

Burst 28 - The Cosmic Archipelago, part III



Released: 6 February 2018
Duration: 24 minutes, 48 seconds

Download the .mp3 audio file

A hundred years ago cosmologists were struggling to understand the nature and structure of the universe, and at the heart of this struggle was the island universe hypothesis. Today we find ourselves confronted with a similar question posed at a far greater scale. In order to resolve our cosmic archipelago problem we will have to attempt to reconstruct a history of our universe as a part of a far larger cosmological system, and to do this we will have to extend cosmology beyond the observable universe -- but what, exactly, is the observable universe?

The Cosmic Archipelago, part 1.

A hundred years ago cosmologists were struggling to understand the nature and structure of the universe, and at the heart of this struggle was the island universe hypothesis. Today we find ourselves confronted with a similar question posed at a far greater scale. As we confront these great questions of cosmology, whether a hundred years ago or today, we find ourselves faced with as many philosophical questions as scientific questions when we challenge the boundaries of our understanding. In Part II we focus on cosmological scales of time and what this means for human observation of a very old universe.
