Would the LHC kill its own grandfather?

Not the LHC I know; but mistakes do happen.

The obvious, of course, being that the collider should have been colliding for more than a year now and hasn't. For those who don't know, the Large Hadron Collider (LHC) is a massive (17 mile long track beneath the Franco-Swiss border outside Geneva) particle smasher running on the largest Xeon grid known to man looking to collide sub-atomic particles at near speed of light speeds in order to discover the great mysteries of the very early universe and how it is made up today. Some pseudo-mythological, grant grabbing players scientist are on the hunt for are 'The God Particle,' or 'Higgs Boson'(the particle that all massive things are made up of), and the gravitron's hypothesized movement to dimensions outside of our own.

Two prominent papers have been published recently that suggest the failure of the LHC is due to the experiment's "aberrance to nature." The papers, “Test of Effect From Future in Large Hadron Collider: a Proposal” and “Search for Future Influence From LHC,” cite the Grandfather paradox as basis for their hypothesis. These scientists believe that the Higgs Boson ripples back in time to stop the creation of one like a time traveller Killing its own grandfather.

As asinine as this theory appears, it does bring up an interesting paradox. What does happen when we go back through time and kill our grandfather. Many argue, similar to that of the LHC arguments, that we cannot do it: that our grandfather would simply bend over and tie his shoes as the bullet grazed by his head.

The answer to this paradox seems obvious to me, so it is probably confused (I haven't worked in particle physics since the late 60's), but isn't one of the major goals of this experiment to prove the existence of other dimensions, of possible universes? If there turn out to be other possible worlds, this paradox seems to disappear. Killing your grandfather would place you in a dimension in which your grandfather was determined to die before you were born -- a place outside of your universe where people don't kill their grandfathers.

The scheduled reanimation of the LHC is dated around Christmas. Spacetime will tell.
