In "The Collapsing Universe," Asimov suggests that the current
calculations about the volume and mass of the Universe put it
within an order of magnitude of being a large black hole.  He
shows a good analogy of why the larger mass you have, the less
the density needs to be for a black hole.  Of course, this
stuff only occurs at the edges.  In the center, (where we presumably
are) things carry on as normal.  The book is good reading.
