    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.

    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."

    It's circular.

    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.

    Disagree

    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.
