Semi retired old time computer nerd who started programming on a Commodore Pet.

Since I'm also active in the Physics forum I should add that I started as a theoretical chemist, moved into solid state photochemistry and finally worked in industry as a colloid scientist. I only became a full time computer nerd in 1997.

comment What's the physical meaning of a “sphere”, and a pair (or even a series) of “concentric spheres”, in a region with Schwarzschild geometry?
@user12262: I'm not sure what you're asking. Are you asking how we define the $r$ coordinate? You seem to know enough about GR that surely you know this.

Why is this a bad question? It seems an excellent question and quite a hard one for the non-relativity nerd. See my answer - it takes a lot of explaining. How many of the site members could have answered it? Not many would be my guess.
