I would love to suggest an edit for the video described in the Title, or maybe a clarification video that details the photo of a black hole taken by Katie Bouman using the Event Horizon Telescope. Sal's video was accompanied by "artist depictions" of what a black hole looks like but now we actually have the capability to view one for ourselves. 

The history of the Event Horizon Telescope itself is interesting as well, and I would love to see what Sal's opinion (or any other instructor's opinion of it) is if they could take the time to make a short video on it.
