The mass estimates I used included the best estimates for those.

Using normal physics, however, you can breed H & He into structural materials but it takes a long time. I've wondered if we still see stars because they happen to be the best containers for breeding heavier elements.

O, B & A stars are fine for rapidly breeding heavy materials, and good if you need a lot of energy for computation, but you get it for a much shorter time (millions rather than billions of years). There appear to only be 2 ways to do this -- (a) beam your information over to the new D.S. just before your star blows up/goes out; (b) navigate your star into a close collision with another star and deconstruct & reconstruct your D.S. around the new star. It isn't clear which is more efficient.

Kind of tough on the teeth, I'd presume.
