Hawking Radiation

Sometimes space news sneaks by without getting much attention. 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.
