frame dragging

Quick Reference

The distortion of space and time by a rotating object as predicted by general relativity. It is also known as the Lense–Thirring effect, or Lense–Thirring precession, after the Austrian physicists Josef Lense (1890–1985) and Hans Thirring (1888–1976), who first predicted it in 1918. Spacetime itself is dragged along with the rotating body, producing an effect on a spinning object near the rotating mass which causes the spin axis to precess. Evidence for frame dragging has been observed in a gas disk around a spinning black hole, and in precession of gyroscopes orbiting the Earth aboard Gravity Probe B.
