  13. What would it take to make a black hole?  This is obviously a fanciful
  14. question, but I'm looking for real answers, not Star Trek answers like
  15. "beam a whole sun into the space of a sugar cube."  How much mass do I
  16. need to collect?  How much pressure do I need to subject it to?  Where
  17. do I keep it?  How long will it last?
