The Doubly Warped World of Binary Black Holes
This computer visualization shows light from accretion disks around two supermassive black holes. The extreme gravity warps space-time, bending the light rays. One black hole is 200 million solar masses, the other 100 million, with their disks shown in different colors to track the light.
