Supermassive Spinning Black Holes

[Gibsense]

It's important to understand that a black hole is not the star itself. The event horizon results from the star's gravity, while the remnants of the star reside near the theoretical singularity.

How fast can a black hole (BH) spin? Is there a limit to frame dragging? As a result of spin in a supermassive black hole, could a star be geometrically forced into a torus shape rather than a singularity? Could the ultimate spin of a toroidal structure frame drag enough to cut its connection to spacetime?

If a spinning torus were suddenly freed in Euclidean-dimensioned space, would its centrifugal energy cause inflation? Would it simulate a black hole in reverse? Could this lead to the creation of a new universe? As it expanded, would its spin decrease? At a radius of about 7 billion light-years, would the curvature cause the slowdown to be accelerated as the gravitational curvature of the torus or sphere dominated? Would the curvature, similar to gravity wells but reversed, become more "attractive, "speeding up the expansion?

Are we just beyond the spin slowdown of our universe? Can spin be determined by a flattening at the poles? Are differences in spin influenced by varying directions of observation? Can a connection be made with the Hubble Tension? Could such a process represent a continuum where a feeding black hole in one universe causes expansion in another as an ongoing process?

What do you think? Let me know!
I am using a tornado as an analogy.

Those are some 15 good questions.
I do not think there is any analogous object when referencing a black hole, as they are unique. A tornado is formed from the outside.

Imagine material falling into a black hole whereby it falls in nearly parallel to the surface of the event horizon. The spin is continued inside the space defined by the event horizon (which spins at a similar speed).

Material 'recently' falling in has a speed on the inside of the event horizon. The gravitation of the star (which is near the supposed singularity) causes material to fall. The material falling spins faster (like a skater pulling its arms inward). Speed and frame dragging get bigger.

The analogy with a tornado is that low pressure = gravity. It is calm at a tornado centre. There is no material spinning in the centre of a Torus. A tornado grabbing material and hurling it around in a circle eventually sends it catapulting off as if centrifugally ejected. The Torus may do the same to create a Big Bang

A thought experiment! I picture material spiralling into a black hole like a skater pulling in their arms to spin faster. Inside the event horizon, the material gets whipped around quicker and faster due to the intense gravity and frame dragging. The analogy is like a tornado with gravity being like the low pressure pulling everything in. Similar to how stuff gets flung out from a tornado, maybe, just maybe, something similar could happen in a torus-shaped structure within a black hole, leading to a Big Bang-like event. How's that? Maybe.

The Accretion disk on the outside near a black hole viewed from afar is shaped like a Torus and forms mega effects with feeding black holes (Quasars). A similar situation inside the event horizon BUT by definition, nothing can get out into our universe therefore it forms another Universe!
