Can spatial rotational dimensions be associated with the time dimensions? If so this will “reduce” the Kerr metric.

Can a dead in the water BH, w/o charge, with an angular momentum of free fall be given vector coordinates that are recognized as a progression of time?

Space/Time fabric is non-influential on this BH. The BH is adrift as all spatial coordinates are passing it by. The passing of time as represented by moving linear distance cannot mark the BH as localized (fixed) because it position is not stagnant. Its free fall in linear Space/time is its own time dimension. Kerr metrics would only be applicable if the BH attracted a Light accretion disk and was part and parcel of the expansion of Space/Time.

It could pop in and out of existences! lol

Apologies if I misinterpreted. lol

It's penchant for popping in and out of existence could make its attracting a Light accretion disk problematic. lol

Allow me to clarify, such a BH would pop in and out of 3D existence. It's essentially a 2D S/T curvature. lol

I think that u are talking about an Einsteinian blackhole, in an Einsteinian universe. Therefore u expect an Einsteinian answer. I can only offer my non-Einsteinian thorts.

I doubt that any macro thing can pop in or out of existence. Praps a micro thing can, eg a photon.

There is no such thing as a time dimension, eg spacetime (time can only help any popping in a simple sense).

Perhaps a blackhole can suddenly become visible, & in that sense disappear (ie disappear by appearing).
Because a blackhole can be very small (ie i mean not very massive). After all it only has to be massive enough to reduce the speed of light to less than c".  The full speed of light is reduced near mass, ie c becomes c'. And then if there is plasma or gas or liquid then c' reduces to c" (due to refractive index).

A weak blackhole might be blue, due to Cherenkov radiation.
