Any activity that changes a past event will trigger a change in the physical movement of the people who lived then. To be precise, spermatic fluid will be displaced. For example, all the people connected with the LHC and even those who have read of its problems will have shifted their physical positions.
The result? Children who would have been born won't be. Children who wouldn't have been born will be. Perhaps a girl rather than a boy, or perhaps a few months earlier or later. This in turn generates a cascade of similar changes affecting anyone who comes into contact with them (or fails to do so).
A similar effect can be expected from women, whose physical positions will later be altered at the time of conception (or non-conception).
Consequently, ANY time travel contact with past generations of Earth people or their habitat, constructs and so on will immediately terminate all future events, including the one that produced the individual who is going into the past. This could be a great explanation for all those UFOs that are visible for a short time, then suddenly disappear. Each of those UFOs could be the "first time" that a time-traveller has gone into Earth's past.
As for time travellers targeting the LHC, they would be better advised to reach back into the more distant past and zap the theoretical physicists whose original work formed the foundation for the LHC.
If the LHC is to be stopped (which I think it should be), it should be by people living here and now, not by assassins from the future.

That would explain some things ...

There is another which states that this has already happened. -Douglas Adams

I thought we had, y'know, SCIENTISTS working on this.
Also, it is a paradox to go back and prevent your grandfather from being hit by a bus. If he wasn't hit, what motivation would your future self have to go back in time and stop it? If nothing else, it would create an infinitely repeating loop.
I know io9 likes to show us these "science" articles once in a while that get me riled up because of the lack of science and the quick assumptions, but this is ridiculous.
No, no... okay. The one where Americans are incredibly overweight compared to most of the world ('cept oddly England & Mexico) is caused by a disease that, for another strange reason, skipped Colorado and the Northwest of the United States was a lot worse.
Still, give me a break here.

(An addendum)
Didn't Stephen Hawking disprove time travel using Occam's Razor?

Very true...the lack motivation to do something from a already changed past prevents *any* deliberate alterations to the timeline.
The only changes possible to make would be ones were your actions changing them would not be effected by them being changed.
That would be;
a) Accidental changes.
b) Changes that have no apparent consequence in the time you departed from. (eg, you can go back and change something as long as it wouldnt effect the present you left from...for example, going back in time and barying something that wont be found till much later)
So your perfectly right there.
However, the infinite repeating loop has nothing wrong with it, as it would never be infinite.
The very act of moving your mass back in time unavoidably changes the future in subtle ways. (movement of air, etc).
This would indeed "loop around" as changes to the past would mean you traveled back in slightly different states. (even if its just on the atomic level...different heat, air particals, energy charges etc).
However, this "infinite loop" would stop the moment the timeline is stable.
That is, the moment the past results in a future which results in *exactly* the same past.
Imho, this would mean from an outside observe the universe always "takes the path of least resistance" to have a stable timeline.
And that could mean...unlikely though it probably is...that a timeline could seem to be depending on time travel for it to happen. This isnt a paradox *because it could have happened anyway*, merely we never saw it because it looped around bazzilions of odd times before stopping at what we do observe.
Of course, the more likely explanation is the loops would probably stop at "no time travel happened at all".

And (this is more of an opinion) if people from the future are trying to stop this, I see that as great news. Apparently, Future Man is can travel through time. Sounds like a win to me. And what if they used theories developed from the Higgs Catastrophe to develop time travel? Doesn't that qualify as a paradox? Unless of course, these are aliens trying to stop the project. There is no win there, just awesome.

Causality is all a matter of perspective.
