no it’s not. it’s just to make particles clash at a preposterous velocity to see what happens when you force quarks away from their triplets.
there is a little less than a chance in five hundred that a singularity will show up. it’s likely that it’ll dissipate. however, given the heat and the weird situation in which timespace will be at inside that big collider, it might just be that the odds of the singularity stabilising and becoming a baby black hole. (the odds were calculated at a little less than 1 in 10 000). in that case, there’s a chance a little over 10% (making the whole shebang 1 in 100 000) that the black hole itself will not poof away. in which case we get doomsday before christmas.
yes, but in a normal condition, timespace borrows energy from the future in the form of a particle-antiparticle pair which undergoes anihilation and releases a lot of energy — at which point the baby black hole goes. what we don’t know is whether or not in weird simulated conditions this will hold, as the whole “borrowing energy from the future” thing is about as complicated as quantum goes.
now you’re just skimming through the wikipedia. what arguably happens at the atmosphere is the formation of strange matter, and that’s only provided a massive ammount of energy, like a solar storm. nothing to do with black holes. as for strage matter, it might be more risky in a lab than in the skies because there’s a lot more energy going on in the LHC, and the two mainstream physics standard models of now are particularly contradictory when it comes to strage matter: one says it will dissipate under lots of energy, the other predicts that if you give it matter and heat it will subverting the whole matter around it into strangelets.
at any rate, what you’re dismissing here, Ryan, is that there is a chance a weird thing comes up from this test. the chance is very small — but it’s not a pointing at others and saying “ha, told ya” matter. no matter how small our calculated risk is, we shouldn’t treat “oh, and there’s a risk we’ll anihilate the world in the process” as someone else’s problem! there still is a chance. a small chance is nice that way: it’s not like saying it won’t happen. it just might happen.
