An artist’s rendition of a black hole surrounded by a glowing accretion disc of material, the light from which is warped by the strong gravity. In principle, energy could be harvested from a spinning ...

Spin in a black hole produces an effect called "frame dragging," an effect where space-time is curved around the spinning black hole by the rotation of the black hole. This profoundly affects ...

In 1972, physicists named William Press and Saul Teukolsky described a theoretical phenomenon called the "black hole bomb," where mirrors enclose, reflect, and amplify waves coming from a spinning ...

An experimental setup mimics a “black hole bomb” first theorized in 1971. The spinning cylinder with circuitry is true to the original idea, showing that it can be plausible. Electrical waves spin off ...
