The Black Hole Photon Ring - Testing General Relativity Through Black Hole Imaging

NYU Physics via YouTube

Overview

Explore a fascinating physics seminar that delves into the visual characteristics of black holes, particularly focusing on the theoretical "photon ring" surrounding the M87* supermassive black hole. Learn about the multiple mirror images created by photons orbiting the black hole and how these images reveal crucial information about space-time geometry near the event horizon. Discover how Einstein's theory of general relativity predicts these phenomena and understand the significance of the proposed NASA Black Hole Explorer (BHEX) mission in potentially confirming these theoretical predictions. Gain insights from Vanderbilt University's Alexandru Lupsasca about how measuring the photon ring could serve as a precise test of general relativity and advance our understanding of black hole properties.
