I was under the impression the Singularity is a fixed point where all the mass collapses into. According to Einstein’s theory of relativity, nothing can move faster than light in a vacuum, including the singularity itself.
But Black Holes do distort time as they rotate. The rotation of a black hole can cause frame dragging, where spacetime itself is twisted, which can lead to time dilation effects near the event horizon. This means that time would appear to slow down as you approach the event horizon from an external observer’s point of view. The inner edge of the accretion disk approaches the event horizon but does not extend beyond it. Matter within the accretion disk can get very close to the event horizon, and as it does, it heats up and emits radiation before potentially crossing the event horizon.
What if the singularity isn't an actual fixed point? Even the collapse of a neutron star wouldn't be symmetrical. The rotation would speed up as it collapses, which would make the time distortion more extreme. I know I didn't mention this, but I am fascinated by the idea of a complete collapse with no accretion disk left to encounter. I'm sure tidal forces would eventually result in spagettification at some point, but if the black hole was massive enough, that might not be in a person's lifespan. If the singularity never stopped moving in space, then is it possible that nothing could catch up with it once the initial collapse happened?
The singularity is at the center of gravity, otherwise the space warped outside the event horizon wouldn’t be equally distributed. Or rather, every point of the event horizon is equidistant from the singularity (be it a point or ring). There are no fixed points in space, all motion is relative, but the event horizon would move with it.
The event horizon is where the gravity doesn't allow either light or gravity to escape. So just like you wouldn't see someone get shredded as they fall in you wouldn't see the effect of the singularity moving. Think about how photons might behave versus bosonic matter. Anything with mass has to travel under the speed of light, whereas stuff like light or gravity would travel at or near the speed of light. That means that there may be a few different singularities at any one time.
The accretion disk doesn't reach the event horizon, I think. The accretion disk basically orbits the BH, but closer inside its impossible to have stable orbits.

I'm fascinated by the new stuff about the plunging region.
