You can find this on Netflix. It's an extraordinary film, made by Peter Galison, a scholar in my area who studies scientific imagery in particular. It's the story of how they captured the first ever image of a black hole. The film is beautifully made, not some dry doco. And take the title literally, black holes really are the edge of not just what we know, but of reality itself. You can't imagine anything that can match the actual reality here.
