Theoretically, if an "intelligent," real-time control program were developed for the UC, then autonomous, artificial nanoscale organisms could be assembled. One of the most obvious applications of a UC - if its construction were ever practical - would be the genetic manipulation of lifeforms at the atomic level to cure disease, correct congenial defects, or expand their capabilities in beneficial ways. Unlike the simple atom by atom nanotech constructors common today, a UC would combine millions upon millions of atoms in a parallel process that could produce materials or mechanisms of unmatched intricacy on a scale currently not possible even with the best nanoscale foundry. and thus arose the need for a more generalized theory encompassing a "Universal Constructor" (UC) that would be able to handle such arbitrarily complex nanoscale design problems. Universal Constructor: Theory, Principles, and Practice, by Wayne Yin. He could turn that asteroid into a bundle of candy bars or soy food before it hits. They would be caught in the blast unless they zip out of there before an asteroid hits, and at this point JC Denton is a universal constructor and can rearrange atoms or molecules in any way he wants. They could do the same thing but it would be counter productive. In Mass Effect 2 a mass relay only destroyed a solar system because of that. The Reapers can't remotely detonate mass relays like that unless they hit them with an asteroid or something.



This is after JC Denton has perfected the merge with Helios, and assimilated to Alex Denton's nanotechnological architecture.
