I got 100%, did I win?

Just viewed the poll results, everyone agrees with me, 100% is the poll result for what I picked as the answer.

Yahooooooooooooooooo!

I picked the second one, finite size and density. Infinity is an "inconcievable" so pick that one, and admit to 'fooling yourself'

Hi Labguy,
I am much in favor of checking current thought, as you say,
on this and other things. I notice that you do not
include the possibility of finite mass with infinite density
(that is, finite mass and zero volume).

I will try to guess after I have thought a little----certainly
do not know the answer right off!

Do we really know what singularities are?
String theory is far from proven----isnt even complete yet.
The classical GR geometry is probably just an approximation
to a quantum geometry picture of a singularity, that perhaps
does not yet exist in anyone's mind?

This is very puzzling.

Anyway congrats on posting an interesting poll!

Well, I suppose calling it a "singularity" means that it has infinite density by definition, but I'm guessing that "correct definition of the word" is not what you were asking. "Finite mass with zero volume" is what "singularity" means, but for reasons related to time dilation, I don't think true singularities exist.

I chose "Not...Defined...".

A. I agree.
B. Me too.

Well I voted for "not necessary to be defined as singularities"
but I would certainly appreciate some more discussion.
Not sure what comfort time dilation gives to one unfortunate to fall into a black hole. May he not encounter all the nastiness
we may reasonably expect and conclude that it is a true singularity. Please provide some detail.
