Well if we're going to be completely scientific about there's no a zero percent chance, but there's never a zero percent chance of anything. Most of the black hole talk is scaremongering, and the papers published on it have been ripped apart by peer reviews. We're not doing anything that isn't already happening in the upper atmosphere. Why is the LHC a waste of money? Becuase you could spend the money on something more usefull that will physically help us. Still why waste 4.4 billion on an experiment that has slight chance of killing us? Why take the risk? What will we get from it? The risk is so minimal that I call it inexistant. They just want to scare you, especially The Sun since they can have sales this way. And on what would you say that money could have been? To me, this is not a waste of money. There are so many other things you can spend money on... But there is still a risk. Do they know what they are doing? Who knows what will happen during this experiment. I would rather not take the risk because the consequences could be very severe.
