You explained it very nicely (although, I'm not sure if I got all of that nerd stuff), but time and again, scientists have admitted that they were wrong about certain things and no one can guarantee the results yielded from an experiment to be always accurate, let alone the possibility of it backfiring and producing entirely different results than what was expected. Now, I'm aware that CERN nerds aren't a bunch of foolish idiots gathering together to do something they don't know about, but they don't know what the results would be. Thats the whole point of experimenting, isn't it? Don't mistake it for me advocating in the favor of they-shouldn't-be-doing-it, I'm just sharing my thoughts that we may be geniuses, but we're not know-it-alls, despite them doing it in a controlled environment.
Anyways, I'm not sure whether the results of this experiment would be entirely accurate as I am a believer in 'laws of physics aren't the same everywhere in the universe' theory. But kudos to the team as knowing something is certainly better than knowing nothing. I'm sure it will help change the lives of many people in way or the other, courtesy of the outcomes of this experiment, regardless of good or bad, or at the very least, teach us at least something about how our world works.
EDIT: Why isn't anybody talking about if it opens up the new dimensions or even a parallel universe? Man, I've dreamed about this my entire life!
