infallibility is a bore and everyday is a learning experience but i still don't think centrifugal force could hold down an atmosphere as for all other statements granted i was wrong... but no one touched the statement about the economic ramifications of such a project...
if you could overcome all the inherent engineering problems with building a sphere world why when your moving this many solar systems worth of matter around this sun don't you sift out the important parts? I think the only thing you should be able to extract from ringworlds and sphereworlds are organics, population and energy which is everything but minerals i guess what im saying here is why on earth are you mining resources from something you built?! I think looking at the real cost of one of these things it'd be more efficient to build a huge close-formation satellite field around the star to gather its energy...If it ever gets built it will be more a monument of achievement (tower of Pisa or Lady Liberty) than a useful source of resources though it'd be great place to stick all those naggy scientist characters!!
military strategms of a sphere world... If you can somehow manage the intense heat of the star that a sphereworld would generate>>then when someone attacks you why dont you just aim that crap in their general direction....... more food for thought
also i want to give a hand to all the great minds assembled here i've taken 5 AP courses including AP Calculus and AP Chemistry and i could neer have carried on such engaging and fascinating conversations and everyone has good points...even when they prove me wrong!!
