The LHC, the Higgs Boson, and Fate
Reader Maximum Prophet sends a piece from the NY Times by the usually reliable Dennis Overbye reporting on a "crazy" theory being worked up by a pair of "otherwise distinguished physicists": that the Large Hadron Collider's difficulties may be due to the universe's reluctance to produce a Higgs boson. Maximum Prophet adds, "This happened to the Superconducting Super Collider in the science fiction story Einstein's Bridge. Now Holger Bech Nielsen, of the Niels Bohr Institute in Copenhagen, and Masao Ninomiya of the Yukawa Institute for Theoretical Physics in Kyoto, Japan, are theorizing that it's happening in real life." "I'm talking about the notion that the troubled collider is being sabotaged by its own future. 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."
Please don't anthropomorphize particles. They don't like when you do that.
Hehe. I quite like anthropomorphized particles: http://www.particlezoo.net/
Well you could have just linked the Wikipedia article instead of copying and pasting it ;)

A pair of entangled particles has the property that, if someone takes a measurement on each of them, forcing each into one of a pair of eigenstates, knowing which state one of them collapsed into tells you which state the other one collapsed into - even if the separation between the two measurements is spacelike rather than timelike (i.e. even if a signal from one of them "telling" the other which state to pick would have to propagate faster than light.)
But you can't force your particle to pick one of the two options for its own collapse, and thus force the other to pick a state of your choosing and send a bit of information faster than light. The PARTICLE gets to make the pick. You can't distinguish whether the particles communicate FTL, the pick was already made when they initially became entangled and carried by some "hidden variable" until the measurement (though there's reason to believe it's not a hidden variable), they were just predestined to act that way, or whatever. (Physics says WHAT it does but, at least so far, not HOW.)
The most you can do is measure a DIFFERENT thing about the particle when you force the collapse (such as the polarization along a different axis if you're measuring polarization), in which case you lose all knowledge about how the other particle's measurement came out.
So if there is an FTL communications link there, it's useful for the particles but apparently not for us.
This is probably good. If we had a reliable FTL signal link we could pretty trivially (using special relativity and things moving moderately fast) turn it into a future-to-past communication link and blow the hell out of causality. So far the only maybe-future-to-past comm channel that comes out of current paradigms (AFAIK) involves galactic-scale masses and energies.
Does that explanation help?

The English "or" maps to the operator "OR", but the English "either ... or" maps to the operator "XOR".
In other words,
scary or wonderful => scary OR wonderful
either scary or wonderful => scary XOR wonderful
