Chandra and NASA's Hubble Space Telescope later collected data from the event's afterglow, and together the observations led astronomers to conclude that the powerful explosions can result when a black hole and a neutron star collide, producing another black hole.
In science, computing, and engineering, a black box is a device, system or object which can be viewed in terms of its inputs and outputs, without any knowledge of its internal workings. Its implementation is opaque. Almost anything might be referred to as a black box: a transistor, an algorithm, or the human brain. To analyse something, as an open system, with a typical black box approach, only the behavior of the stimulus/response will be accounted for, to infer the box. The usual represent
