From a NYTimes article about the latest escapades at CERN (other than terrorist physicists):

A pair of otherwise distinguished physicists have suggested that the hypothesized Higgs boson, which physicists hope to produce with the collider, might be so abhorrent to nature that its creation would ripple backward through time and stop the collider before it could make one, like a time traveler who goes back in time to kill his grandfather.

Really, what commentary do I need to add to that? Read it all here.
