When black holes collide and merge to form even more massive black holes, this violent process sends ripples surging through the very fabric of space. A new model indicates how these gravitational waves interact with each other as they spread through space-time, the unification of space and time popularized by Albert Einstein’s theory of special relativity.

By presenting a clearer picture of how black hole collisions set space-time “ringing,” the model could indicate how scientists on Earth can learn more about the events that launch them using gravitational wave detectors such as the Laser Interferometer Gravitational-Wave Observatory (LIGO). LIGO made the first detection of gravitational waves from merging black holes in 2015, with the signal going on to be named GW150914.
