And the rich harmonics of those vibrations, seen through gravitational waves, could hold the secrets to the nature of the fabric of spacetime itself. Today on space time journal club we’ll explore the papers that claim to have detected black hole harmonics. We’ll also give you the latest updates on the most recent – in some cases quite bizarre - LIGO detections.Sign Up on Patreon to get access to the Space Time Discord! https://www.patreon.com/pbsspacetimeCheck out the Space Time Merch Storehttps://pbsspacetime.com/Hosted by Matt O'DowdWritten by Matt O'DowdGraphics by Murilo LopesDirected by: Andrew KornhaberExecutive Producers: Eric Brown and Andrew KornhaberEnd Credits Music by J.R.S. Schattenberg: https://www.youtube.com/channel/UCRl6-nb4iOnsij-vnpAjp0QWhen physicists talk about black holes they’re usually referring to highly theoretical objects – static, unchanging black holes viewed from “infinitely” far away. This makes everything clean and simple enough to attempt the already notoriously complex calculations of black hole physics. But real black holes are created in the violent deaths of massive stars, and there’s nothing clean about that. And we now know that black holes merge – and in the process produce gravitational radiation that we’ve only just managed to detect with the miraculous work of the LIGO and VIRGO gravitational wave observatories. In the instant after its merger, the new, joined black hole looks nothing like the idealized theoretical black hole.Special Thanks To All Our Patreon SupportersBig Bang SupportersAnton LifshitsDavid BarnholdtDavid BoyerDavid NicklasFabrice EapJuan Benetmatt millerMorgan HoughQuasar SupportersMark HeisingMark RosenthalVinnie FalcoHypernovaChuck ZegarDanton SpiveyDonal BotkinEdmund FokschanerHank SJoe PearceJohn HofmannJohn R.
