The singularity is the circumference itself, not the inside. Instead of a
point of no size, it is a (curved) line with zero size in two dimensions,
not three like a point.

I guess GR predicts all kinds of weird stuff if you go through the circle
created by the singularity without getting too near the singularity (not
too near the edge of the circle) but I think of this as angels dancing on
pinheads territory.
