On a positive note, what are the odds that CERN could create a black
hole and feed it enough matter to grow it up so that it is stable? How
much mass would we need to toss into it to make it stable long enough to
get it into space? If we got it there, wouldn't it be a nice thing to
have around for various purposes....
