But I'm not, anymore, a particle physicist. I'm a particle accelerator physicist, and so it's my job to understand how to build the machines that we … - Suzie Sheehy

In answer to some of the questions that we had a few years ago when the Large Hadron Collider started up... "Could it destroy the world?" ...The most convincing answer to me as to why it couldn't, is because we have particles in outer space from cosmic rays and things like that, at much much higher energies than we could ever dream of creating in the lab. And so far they haven't done anything catastrophic to us and we're perfectly fine. So in terms of just reaching a higher and higher energy... it doesn't really matter what we do in the lab. We should be safe on earth from these high energy particles.

So the final thing that you probably shouldn't do with a particle accelerator is: You probably shouldn't destroy the Earth with it. ...People seem to think that when we design new massive particle accelerators that are going to have particles that are huge energies that we've never created before in the lab, that somehow... we just built it for the lulls, and then we're going to destroy the earth with it, and that we haven't quite thought it through, and that we're not quite sure what we're doing... If you're at all concerned, please go to HasTheLargeHadronColliderDestroyedTheWorldYet.com and... you can tell me what you find there.

So we can't use it as a weapon of mass destruction. This is another one... that someone told me that you shouldn't do with a particle accelerator... [Y]ou shouldn't eat it, which is true.
