The @BulletinAtomic Doomsday Clock is at 90 seconds to midnight. In this podcast we discuss why.

The Doomsday Clock remains at 90 seconds to midnight. @decohere and former executive director Kennette Benedict join @JBWolfsthal and @heatherwilly to share what actually goes into the decision to set the time, and how panicked should we really be. ow.ly/ih8q50QuZYn

An article about the Are We Doomed? class I taught with James Allen Evans. The material seems to be ever more relevant. We’ll be teaching it again Winter quarter, and hope to place all of the material online and freely available. mag.uchicago.edu/science-medici…

Excellent article by @majohnso . Perhaps the first time that scientists worried that their advances could doom humanity. But certainly not the last time. washingtonpost.com/science/2023/0…

Did physicists worry there was even a tiny possibility that detonating the first atomic bomb at the Trinity test site in New Mexico might destroy Earth? This comes up in the movie "Oppenheimer." I have a story on the actual history in today's Post. washingtonpost.com/science/2023/0…

The 4th observing run of our gravitational-wave detectors officially starts today!! Stay tuned for lots and lots of black holes. And neutron stars too! @LIGO
LIGO@LIGO
Welcome to the fourth observing run! #O4IsHere O4 will last 20 months, with @ego_virgo and @KAGRA_PR joining us in the run. We expect the detection rate will be roughly twice in our past observing run More news linked from ligo.org/news.php #ObservingRun4

Please join us to watch and discuss the movie Fail Safe at the Siskel Center. As the announcement says, “We recognize this is a bummer. Complimentary popcorn will be provided with every ticket purchase—and drink specials will be offered!” siskelfilmcenter.org/fail-safe @BulletinAtomic

A new paper on gravitational lensing of gravitational-wave sources, led by Mesut Caliskan (started while he was a UChicago undergraduate) with @jmezquiagabravo and Otto Hannuksela. It's surprisingly difficult to distinguish lensing and (bad) luck! journals.aps.org/prd/abstract/1…

Mike Warren was an amazing friend and collaborator. He was one of a kind. Helped invent beowulf clusters (with numerous Gordon Bell prizes to prove it). Also expert at mountain rescue, bicycle racing, guitar, poker, pool, etc. So many happy memories. losalamosreporter.com/2023/02/23/obi…

Fun, fresh paper led by Reed Essick, asking whether GW sources are random on the sky. Although data is consistent with isotropy, we find an excess in the direction of constellation Equuleus. @GWastrology Note: title is pun intended. tinyurl.com/3huhhnmr @farrwill @mayaKfish

Congratulations to Yiqi Xie on publication of "Breaking bad degeneracies with Love relations". We explore using the neutron star equation-of-state to improve gravitational-wave cosmology. And who can resist a New Mexico-inflected pun? journals.aps.org/prd/abstract/1…

UN Secretary-General @AntonioGuterres tells us “the Doomsday Clock is a global alarm clock.” and “We need to wake up—and get to work.” We couldn’t have said it better. @francoisdm @BulletinAtomic thebulletin.org/2023/02/un-sec…

The #DoomsdayClock is now at #90SecondsToMidnight.
Existential threats, like the possibility of nuclear war, put us all at risk.
How do you want to see the world #TurnBackTheClock?

“If there was ever a time for world leaders to take actions to turn back the Clock, it’s now. Until then, it is 90 seconds to midnight.” Op-ed with @JerryBrownGov and @SharonSquassoni on @CNN. @BulletinAtomic @UChicago #DoomsdayClock cnn.com/2023/01/24/opi…
