Scientists confirm that the first black hole ever imaged is actually spinning::The first black hole humanity has ever imaged has also provided us with what researchers are calling “unequivocal evidence” that black holes spin.

    The title kind of misses the point: of course it spins; it would be remarkable if it didn’t.

    The really interesting bit is how relativistic frame dragging is causing its spin axis to precess.

    (Also, the illustration conflicts with the description: it shows the whole accretion disk wobbling instead of just the jets.)

        Frame dragging is when matter drags spacetime along with it. Roughly think of a the wake of a boat disturbing other things in the water.

        The misalignment of the black holes axis of spin, and the axis of the accretion disk is causing interesting frame dragging effects.
