This image may not be used to state or imply NSA endorsement of any company or product Visualisation of a black hole. Second in a series of four images from a computer simulation of gravitational waves emitted by a disturbed black hole. In this frame, the black hole is beginning to return to an equilibrium state. The colour and height of each point represent aspects of the gravitational wave fields; the black line near centre is the apparent surface of the black hole. As the black hole seeks its equilibrium state, it emits characteristic gravitational waves (its 'signature'). Compare with R670/047, 049 & 050.
