Thomas Moynihan is a UK-based historian, and author of X-Risk How Humanity Discovered Its Own Extinction (MIT Press, 2020). He holds a DPhil from Oriel College, Oxford, and is currently a Research Affiliate at Cambridge University’s Centre for the Study of Existential Risk, as well as an Affiliate Researcher at the Berggruen Institute’s Antikythera think tank. He studies how worldviews transform over time, in often radical ways, as more is learned and revealed about the cosmos and our placement within it. In particular, he is interested in our species’s changing sense of orientation within not only time, but also relative to all the ways things—in the broadest sense of the term—could have gone otherwise. Thomas and his work have been featured on shows and publications including CBC Radio, BBC Radio 4, ABC Radio, 80,000 Hours, The Atlantic, Futures Podcast, New Scientist, The Guardian, Aeon, Noema Magazine, The Independent, MIT Press Reader, Vice, and Tank Magazine.
