I was just trying to inject a little humor on the topic as other's have done. I am certainly no scientist. My first instinct was to use the phrase "the world did not implode" which would have been more like "sucked in" and not really "blow up" or explode. You are right, they did not collide this time on the first trial, but a few protons will when they fire them off at the same time in opposite directions in a few months. So I guess the planet is safe until then :-) So everyone go out and hire lots of escorts and have lots of sex before the end of the world! just kidding, I am pretty sure if Hawkings thinks it's safe, then we can all relax.
