Large Hadron Collider - Creation of New Universes?

Was reading up on the Large Hadron Collider today and got to thinking. We're going to use it to create conditions similar to those just after the "big bang" in order to hopefully learn more of the origins of our universe. I just got to thinking what if each time we run the thing, we end up creating tiny universes that last only a split second to us, but billions of years, such as in the case of our own universe, to it. I wonder the possibility this could actually occur.
