Not everything wows like gravitational waves or spacefaring sportscars. That’s the case with the recent discovery of earliest stars in the universe. In a Nature paper published a few weeks ago, Judd Bowman and collaborators report a signal from the very first stars to form in our universe. The same result also hints at brand new physics that may help explain the nature of dark matter. This result flew under the radar in part because it’s a subtle and clever result that requires a bit of interpretation. Today we’re doing a Space Time Journal Club to explain this discovery. We’ll follow that with the solution to our recent trebuchet challenge question.Written and Hosted by Matt O'DowdProduced by Rusty WardGraphics by Grayson BlackmonAssistant Editing and Sound Design by Mike Petrow and Linda HuangMade by Kornhaber Brown (www.kornhaberbrown.com)Special thanks to our Patreon Big Bang, Quasar and Hypernova Supporters: Big BangCoolAsCatsDavid NicklasFaisal SaudAnton LifshitsJoey RednerQuasarTambe BarsbayMayank M.
