[quote]The death star's shielding and contained computer regulated environment WOULD ALSO keep it operational [b][i][u]indefinitely[/u][/i][/b][/quote] [i]Do you have anything to support or substantiate that claim?[/i] [quote]The Halo systems do have a crew; AI and nano tech for self repair. Does the SAME purpose as a manned crew.[/quote] [i]That's all a part of the Halo's system, though. No outside forces required. It's all automated. The Death Stars require living crews to maintain them and repair any damage sustained. What I'm asking is, if Halo fired and wiped out all life, which one do you believe would stand the test of time longer? A Halo or a Death Star?[/i]
