- Okay, I understand now.

- To have a well defined interior radius you definitely do NOT want 'interior
- Schwarzschild'. But I guess I can imagine a 'radially rigid' sphere with
- its surface just outside R=2M. The 'distance to center' would depend on
- how it maintains its shape. I don't want to speculate further. I think
- this is a much hairier problem than it first appears.
