They did the initial test, of a single particle, and was announced as a success. The second test is in roughly 2 weeks time and that'll be the real atom smashing, with 2 particles. But, they say it is an abosolutely astoundingly minimal possiblity that any damage will even come to the testing facilities. Pretty safe in my book, fantastic to look at the possible applications of the results in 20-30 years time. Do not fret folks, a 16 year old girl already killed herself over the last test, that's one person too many.
