Ah OK, now I get it. As it turns out I was privileged to meet Dr. Forward
at a conference. Interesting character, very flamboyant, dresses funny
(ascots), lots of interesting ideas. He used to be a Lockheed guy a long
time ago, was in our "Big Ideas" group. He wrote a book proposing an
earthbound zero-gravity chamber by creating a lump of neutronium and making
a hole below it where the gravity from the superdense ball of neutronium
would exactly counteract gravity. I did the calcs (about 25 yrs ago) which
convinced me a ball of neutronium that size wouldn't be stable on earth.
Any ball of neutrons large enough to hold itself together against neutron
decay would continue to form more neutronium on its surface until the earth
became a really hot 300 meter diameter ball of neutronium. The transition
would be something like what happened to Jupiter in AC Clarke's second
Robert Forward is a super smart guy but I think he missed on this one.
