Black-hole physics
Frame-Dragging
The twisting of spacetime by a rotating mass, which drags nearby matter and light around with it. Extreme near a spinning black hole, it creates the ergosphere; it is tiny near the Earth, where it was measured by the Gravity Probe B and LAGEOS satellite experiments — a direct confirmation of a subtle prediction of general relativity.
