How To Photograph A Black Hole
Katie Bouman, a Ph.D. candidate at the Massachusetts Institue of Technology, and a team of astronomers wrote the algorithm that took radio wave images from the Event Horizon Telescope and stitched them together to create the first image of a black hole. Predicted by Albert Einstein's theory of relativity, a black hole had never been directly observed — until now. Bouman describes the process in this 2017 TED Talk, two years before she helped bring the image to the world.
