Mist, anyone?
meh, string theory is bs
Anyway, I'd be more worried about Quantum Zeno Effect if Lawrence Krauss (one of top names in modern day physics) manages to overcome "safeguard" of gravity when we're Observing dark matter. If he does defeat that obstacle on his rather gloomy theorem we might be more screwed up than by any LHC paranoidisms
Thankfully that hasn't been apparently case but mere idea is creepy
