Avery Broderick on a Black Hole Breakthrough from the EHT

Explore the groundbreaking discovery of the first image of Sagittarius A*, the black hole at the center of our Milky Way galaxy, in this captivating episode of Conversations at the Perimeter. Join hosts Lauren Hayward and Colin Hunter as they interview EHT scientist Avery Broderick, who leads the Event Horizon Telescope (EHT) Initiative at Perimeter Institute. Delve into the fascinating world of black hole imaging, learning how an "Earth-sized telescope" was created using a network of eight radio telescopes across five continents. Discover the significance of this landmark achievement, the challenges faced by the global EHT collaboration, and the innovative techniques used to capture the image of a black hole 27,000 light-years away. Gain insights into the nature of black holes, their formation, and their impact on galactic structures. Broderick, holder of the Delaney Family John Archibald Wheeler Chair at Perimeter, shares his passion for "fire donuts" and explains complex concepts in an engaging manner. From the public fascination with black holes to the future of space-based EHT projects, this hour-long discussion covers a wide range of topics in astrophysics and cosmology, offering a unique glimpse into the cutting-edge research that's expanding our understanding of the universe.
