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.)

Does the black hole spin? Or does the stuff outside the black hole spin? 🤔

It's in space and everything is relative, how do we know *everything else" isn't just spinning around the black hole? 🤔

Because that would require a centripetal force on everything else, which obviously isn't the case.
