Singularity or just a very small, massive shell?

[Vorde]

The easy way out is to say that a singularity has a finite mass and an infinite density.

However we don't have a good mathematical description of a singularity, so we don't really know.

Are singularities actually finitely dense? The basis of the singularity is that gravity is so strong that the object contracts without stopping and will never slow down as their is nothing to stop it( I could be wrong in this as shown by my previous immense lack of understanding). Will it really become infinitely dense or do we just say that because it will continue getting denser and denser to the point where it would no longer make any sense or even matter to measure the density? I read something on the internet about the Schwarzschild radius but I think it was talking about the size of the event horizon instead of the actual singularity.
