Some people are saying that when they switch on the large hadron collider the world will end. A black hole will eat the alps and then the rest of the world. Armageddon, you know. Other people, collider people, say that it is all hype and that it is only possible that the activation of the collider could produce particles that may exist for micro-fractions of seconds and pass harmlessly through the earth.. Harmlessly through the earth.
