Stop and think a bit. (Note that I'm no longer arguing whether the 
universe *is* a black hole or not. :-)

Take a sphere (not a ball). Put dots of different sizes on it. Which is 
the dot that's closest to the "center of gravity"? Where is the "center" 
of the background radiation, if background radiation is literally 
everywhere?

Could be. As I've said, you seem to have a better grip on this than I 
do. In this case, note that the singularity isn't at the center of mass. ;-)

In any case, I think we've beat this dead horse enough. I'm going to 
stop trying to figure it out. Interesting or amusing information is 
still appreciated.

     It's not feature creep if you put it
     at the end and adjust the release date.
