Physicists are weird

OK, I confess: I completely lack the tools and background to evaluate this claim:

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.

Except for one thing: the proponents of this idea are operating in the world of pure speculation, and have no evidence to support it, yet. That tells me that I'm best off provisionally rejecting it. I'll start incorporating crazy counter-intuitive notions about the nature of the universe when the cold implacable hand of the universe starts shoving them down my throat, not before!
