Kerr Black Holes, Spin & Frame Dragging: Observation, Measurement & Evidence

Real astrophysical black holes are expected to rotate. Black-hole spin influences accretion efficiency, jet power, gravitational-wave merger signals, tidal disruption behavior, and the growth history of supermassive black holes.

How verification works →

Real astrophysical black holes are expected to rotate.

supported

Rotating mass drags local inertial frames, an effect called frame dragging.

supported

Relativistic X-ray reflection spectra, continuum fitting, quasi-periodic timing behavior, and horizon-scale observations constrain spin-dependent accretion geometry.
