I am the greatest votary of common sense. Pl do apply that on BH.

Any non zero radius value, however small, is deterministic, and will pose no problem.
You should well remember my oft stated position on that topic.
Which is ?
That in a truly self-consistent metric theory of gravity, BH's cannot exist. A formal singularity may, but is a purely idealized artifact that assumes infalling matter offers zero resistance all the way down to a notional zero radius. Which even then may or may not occur in finite proper time.
PS - how far off-topic is this thread going to wander? Silly question to ask at free-for-all SF I suppose.
No not short-hand for Broken Hill Pty Ltd, it means black hole.
QQ knows what you mean , just being making sure what BH means .
So we are back to 2D into 3D .
2D has no possibility to transform into 3D .
Because 2D can never physically exist .
Why , because 2D has never had depth . Without depth 2D cannot manifest in the first place .
That is only true in our 3-D universe.
Hmmm... what 2D object can manifest otherwise ?
You have defined 2D in the context of a 3D universe. Of course the conclusion is that it can't exist.
It's the fallacy of begging the question - using the conclusion as the premise. To wit:
"Since, in order for something to manifest, it must have depth, then anything without depth cannot exist."
Not quite. Although generally you may be correct. I'll explain when I get back to my home office.
I have defined 2D in the context of its self .
The only way I could communicate what I'm trying to convey is through a 3D comparison .
No. You said it must have depth. A characteristic of 3D.
In the context of 2D, an object does not have depth, let alone need it.
Does the surface of a table exist? how thick is the surface?
2D can never gain depth . Because it can not exist .
Again, this is circular.
Why can it not exist? Because, as you say, it needs to be 3-dimensional (have depth) to exist.
QQ raises a good point. The surface of a table certainly exists, yet it has no depth.
It is the depth of table , the physical manifestation of the table , that allows the surface of the table to exist in the first place .
And yet, the surface exists. And it's 2 dimensional.
