I thought we already knew they spun, given the incredible amount of angular momentum in their accretion disks. Seems like a "duh" thing to prove with image data that the physics data already implied.
I thought so as well but the article says the spin doesn't match the accretion disc, I'm not sure if that's s significant aspect of the discovery possibly? I'm not well versed in relativity to be honest
Edit: forgive me, someone below said pretty much this
What’s an accretion disc?
A disk of matter and gas that accumulates through the gravitational pull of the object in the center.
The are what forms star systems and is also observed around black holes.
