Right i get the halos are a more effective and efficient weapon. (Dont mean to be so aggressive on the forums; by product of dealing with the flood questioning [b][i][u]every single post ive made on validity[/u][/i][/b]) But that wasnt my point or argument. All i was saying IS the death star IS more powerful and with the math's ive posted i HAVE proven it. I KNOW the halos are more efficient and effective at their designed purpose. The death star's shielding and contained computer regulated environment WOULD ALSO keep it operational [b][i][u]indefinitely[/u][/i][/b] so long as nothing aboard broke. The Halo systems do have a crew; AI and nano tech for self repair. Does the SAME purpose as a manned crew. I do get the halos are more efficient but im not questioning, arguing, debating, or bashing that idea. Just saying the death star is more powerful and thats it.
