The Large Hadron Collider in Switzerland

http://bigthink.com/ideas/19542

I was reading this above article listed here on the hadron Collider and my complaint is as it has always been, "What if you guys create the earth into a Black Hole? Since no one has done it before how would you know for sure that you weren't creating one here on earth?" And if you didn't know you were doing it because no one has before what happens to earth and the rest of us?

The Hadron Collider is potentially just as dangerous as building the first Atom Bomb was to Earth. We all may survive it and we all may not. In the end no one really knows. Just how much experimentation can humans do and survive it as a race without going extinct?

This is a question that needs to be asked. Or are we all just a bunch of mad scientists that will witness our group demise(or maybe not)? Poof! The Earth is gone into a human created black hole. No one really knows. And that is the real problem. No one knows.
