Jesus people! The risks involved in this experiment are miniscule and people saying that it is a waste of money and that it is not worth the risk have no idea what they are going on about and obviously know nothing about physics!
The information discovered in this one experiment will push forward the boundaries of science for generations to come and could benefit man kind immensely. I have followed the progress of this project closely since I first read about it and they state that it could lead to technology only as of yet believed to be available in science fiction, such as space folding and even time travel (but only from the time they turn on the machine).
As for black holes, they are actually quantum singularities that will be formed and they will be smaller than an atom and will last for a billionth of a second! Don't forget the forces that create natural black holes in space require the energy and mass of a collapsing massive star!
Anyway, think of it this way. If it does kill us, it'll happen so fast, none of us would even know it had happened. Oh and try the fact that it would destroy the entire solar system, not just Earth!
Exciting times!!!
a response from someone to that article in the shoutbox, may shed light if your actually worried haha l)
