When black holes are perturbed, they vibrate somewhat like a ringing bell. Now astronomers have narrowed down the rotational speed at which that vibration should stop.
As is typical, they did it out by running a simulation. But instead of a supercomputer, they used a batch of Sony PlayStation 3 gaming consoles wired together.
