The LHC wasn't nearly as scary to me as
this!
Although, IF we make a black hole, it would in fact be uncontrollable, and destroy the planet, most likely, but I don't think the LHC could make one.
However, the thing at the top, I think COULD cause a thermonuclear reaction, or make a black hole.
We are actually doing something that exists NOWHERE AT ALL in nature in this Universe!
