Scientist Dr. Randowsky becomes convinced that the chaos caused by the cluster is divine punishment for mankind's use of nuclear missiles. He disables the air conditioning unit, thus rendering the calculator inoperative, and uses a gun to hold off anyone who approaches to restore it. MacLaren, Leduq, and MacLaren's friend Herbert Weisser rush Randowsky, and Weisser is fatally shot. Randowsky runs out of ammunition and, while fleeing from MacLaren and Leduq, accidentally electrocutes himself. The calculator is restarted, and the last of the firing data is transmitted. The missiles are launched, destroying the cluster and saving Earth.
