To put a little perspective on this experiment and ones similar to it, any potential black hole generated would be of such low mass as to be unstable. It would also have insufficient mass to acquire additional mass to make it stable. Essentially the black hole would vaporize. This seems to be the popular view and the one most accepted by the community of scientists. There are other scientists who disagree and share your concern about the potential hazards of the experiment. It does make an interesting statement about the blind pursuit of knowledge without an ethical application by individuals. As technology progresses, I think it becomes more important for individuals to assess the potential impact of their actions. This is hardly a new topic, but one that every person should open their eyes to, particularly when the impact of the 'blind pursuit of knowledge' becomes potentially dangerous.
