What would spacetime look like near a black hole that was rotating at its extremal speed and had a ring of matter orbiting it at ultra-relativistic speeds (just outside the photon sphere), such that the ring was orbiting in the same direction as the black hole’s rotation?
The ring would add to the frame-dragging effect already present due to the black hole’s own rotation. If the ring was massive enough, could this lead to the event horizon disappearing and the formation of a naked singularity or wormhole?
I was thinking a Kardashev III civilization might be able to build such a ring around its galaxy’s black hole. Maybe we should keep our eyes peeled.
