[quote]Weight/mass of mars in metric tons: 6.39 × 10^20 t Average weight of 1 adult human: 70 kilos (1,000 kilos for 1 ton) Thats 14 people for 1 metric ton: Weight/mass of mars: 639,000,000,000,000,000,000 metric tons Thats: 4,500,000,000,000,000,000 adult humans (450,000x 1 trillion exactly) So no the weight of ALL human life forms in ONE galaxy (if each world holds a trillion thats 450,000 of them roughly) IS Barely equal to the weight of mars! (My original guess was 100,000x a trillion, you need 4.5x that JUST to get close to mass of mars and mars is a SMALL planet! Thats also FULL body weight not just nervous system)[/quote] Death star creates a reaction powerful enough to distroy/displace the mass of MEDIUM TO LARGE PLANETS! (Rocky not gas giants) Halo rings only kill life forms in the galaxy upon 1 firing (halos needs way longer cool down than death star too!) The above shows that on a rough average guess of population of 1 galaxy the halos DONT even distroy/displace the mass of ONE SMALL PLANET. So yea by measurement of the reactions the weapons produce THE DEATH STAR'S SUPER LASER is; MORE powerful than the ENTIRE network of Halos firing AT THE SAME TIME! [spoiler]science beiotch! Lol jk but yea math works. [/spoiler] Edit: May have been off on 450,000 x 1 trillion by 1 extra place value; so it might be 4,500,000 x 1 trillion (thats the only error if it is one tho. Also note at 70 kilos per person its 14.2xxxxxx per metric ton, so i rounded down. On 6.39x10^20 tons converted to 4.5x10^18 avg humans i rounded down from 4.568xxxx to 4.5 flat to compensate for the extra 1/4 a person per ton; thats why 4.5x10^18 average people are barely = to mass/weight of mars and not exactly equal to)
