   Thanks to all for your well crafted responses.   
   My thinking is a laymans mix of reading discover   
   mag & a little sci-fi. Such things inspire the   
   imagination in well admimistered doses.   
      
   As for liquids, remember that a liquid is still   
   a liquid despite it viscosity, and a liquid of   
   dense enough viscosity will not pass through   
   a small enough opening, where pressure is not sufficient   
   to force it. In my scenario, the viscosity of the   
   liquid core of the earth would exceed the force to eat it.   
      
   As for the tennis ball, (I wrote also in another response) does   
   a tennis ball have gravity simply based on its spherical   
   shape, mass, and density? If true, I suspect measurements   
   have been taken on such isolated bodies. I would like   
   to read further on that subject. Any references?
