Lets factor in the material in the Kuiper Belt and the Oort Cloud also-could change the picture. Secondly, given enough time (we are giving ourselves enough time aren't we?) Who's to say that "new" material may not be available in higher physical dimensions as described by Rudy Rucker and Clifford Pickover? More reasonably, in Saucer Wisdom, Professor Rucker presented his 'ala' device which transmutes matter into any form desired. We'll have a hundred Petatons of Carbon-60 by next wednesday, mister!
While I'm raving; why not postulate new material around other stars that are A or B class stars. (if I vaguely remember the Hertzsprung-Russell diagrams) and use em' for Dyson shells-no C.O.D.'s please?
-Spud p.s. The dead Tern tied to my head says "Nevermore" perhaps a
Tern would suffice?
