A Times article, pondering the vicissitudes of the Large Hadron Collider in Switzerland, suggests that the great machine may be "sabotaged by its own future." That is, the energies generated may be so prodigious, and the elusive Higgs boson may be "so abhorrent to nature," that its creation ripples back in time to nullify itself. This could be viewed as a protective reflex on the part of the universe, or for the theologically inclined, God's version of "What part of no do you not understand?"
Maybe the whole article is tongue-in-cheek (which makes it no less interesting for that), but with particle physics apparently it's hard to tell. Yet I can't help but wonder: how is the time-travelling theory any different from the proposed project simply being impossible or contrary to the laws of nature, even if we don't yet understand how? After all, if I jump off of a tall building, flapping my arms vigorously, I will fall to my death. Is the prospect of me flying unaided across the cityscape "so abhorrent to nature" that my hypothetically successful flight travels backward in time to insure that I plunge to my doom instead? This suggests that the universe must (retro)actively cut off all kinds of transitions to metaphysically unacceptable outcomes. But if we can never directly view such outcomes, how is this different from the more prosaic notion of the inviolable laws of nature?
