From the Ted Talk by Katie Bouman: How to take a picture of a black hole

Unscramble the Blue Letters


Another thing we can do is take the same set of puzzle picees, such as the ones derived from everyday iaegms, and use them to reconstruct many different kinds of source images. So in our suiialnotms, we pretend a black hole looks like astronomical non-black hole objects, as well as everyday images like the elephant in the center of our gxaaly. When the results of our atgrilmohs on the bottom look very similar to the simulation's truth image on top, then we can start to become more cnfdionet in our algorithms. And I really want to emphasize here that all of these pictures were created by piecing together little pieces of everyday pporhhtaogs, like you'd take with your own personal camera. So an image of a black hole we've never seen before may eullveatny be created by piecing together pictures we see all the time of people, buildings, teers, cats and dogs. Imaging ideas like this will make it possible for us to take our very first pictures of a black hole, and hopefully, verify those famous theories on which scientists rely on a dialy basis.

Original Text


Another thing we can do is take the same set of puzzle pieces, such as the ones derived from everyday images, and use them to reconstruct many different kinds of source images. So in our simulations, we pretend a black hole looks like astronomical non-black hole objects, as well as everyday images like the elephant in the center of our galaxy. When the results of our algorithms on the bottom look very similar to the simulation's truth image on top, then we can start to become more confident in our algorithms. And I really want to emphasize here that all of these pictures were created by piecing together little pieces of everyday photographs, like you'd take with your own personal camera. So an image of a black hole we've never seen before may eventually be created by piecing together pictures we see all the time of people, buildings, trees, cats and dogs. Imaging ideas like this will make it possible for us to take our very first pictures of a black hole, and hopefully, verify those famous theories on which scientists rely on a daily basis.
