Hum, the inner surface is its own enemy? Solar Winds, how to counter them out?
Gravity effect from the inside and out? Some sort of balance on many levels seems to be needed? Opps, our hyper warp ship just ran into something? But we can not see it, but it is there, but is it NOT a black hole, or is it? Would a Dyson sphere look alot like a Black hole atleast in some ways?
