What's the distance from the universe?  Doesn't a distance have to be 
between two events?

How do you measure the "center" from which you take the radius of the 
sphere? I.e., "distance" implies two space-time events between which 
you're measuring a distance.

Certainly with enough mass, a finite universe *could* be within its 
Schwartzchild radius. But I don't think I know enough about this to 
really make any factual statements beyond that. :-)
