In this week's episode, David is joined by Chiara Mingarelli. Prof Mingarelli is currently moving from the University of Connecticut to Yale University and is theorist working on the so-called background gravitational wave signal. Predicted for decades but incredibly elusive, we are on the cusp of detecting this signal for the first time. Learn all about what this signal is and what it means for astronomy in today's episode.
