Veritasium on the black-hole photo

The following video by Veritasium talks about the Messier 87 black-hole photo, but it also talks about our attempts to get an image of Sagittarius A* (pronounced "A-star"), the supermassive black hole at the center of our own galaxy, answering the question in my previous post about why we can't see our own monstrous consumer of stars. As it turns out, and as you'll see in the video, we do have an image of our galaxy's black hole, presumably published at about the same time as the Messier 87 image. The whole thing is mind-blowing. All hail Einstein and his general relativity.
