This computer simulation shows the collision of two black holes, a tremendously powerful event detected for the first time ever by the Laser Interferometer Gravitational-Wave Observatory, which detected gravitational waves as the black holes spiraled toward each other, collided and merged. This simulation shows what the merger event would look if humanity could somehow travel for a closer look. It was created by the Cornell-founded SXS (Simulating eXtreme Spacetimes) project.
