IF it DOES create quantum black holes (not going to eat up the earth) and they exhibit "hawkings radiation"
(which hasn't been proved, even Hawking backed out of a bet claiming it MIGHT be possible black holes transfer information/matter into new universes)
does this mean the LHC is going to be creating handfuls of new universes that break away from ours and into their own.
basically is the LHC REALLY a big bang machine (just not creating the bangs here?)
here's some reading that got me thinking about it. just read the 2nd and 24th paraghraphs.

now this REALLY makes me wonder
I've read.
And I still stick to my story.
The LHC "on a good day" will be able to pack as much as 7 TeV in a collision. If ALL of it goes into a point smaller than a Planck size, then maybe, perhaps, a black hole could be created.
From our frame of reference, it might last as long as 0.0000000000000000000001 second (there are 21 zeros).
What Hawking says -- bet notwithstanding -- is that it would evaporate (meaning that the energy is returned to the rest of OUR universe). The only way we could tell that there was a black hole would be to determine if the small delay (the 21 zeros) took place or not between the moment of the collision and the detection of the new particles by the detector. [I wonder is the detector is located less than 0.0000000000000000000001 light-second away?]
What Sakai says is that this black hole (if it is a monopole -- which is far from certain) might get pinched off from our universe and start growing in its own space time (which means it disappears), leaving behind what I understand to be the reconnection energy (which we'd detect as a Hawking-like radiation).

Either way, I'm not worried.
Every second, at least one cosmic particle collides with a hadron in our atmosphere, with a collision energy over 1,000,000 TeV (the record observation, so far, is 320,000,000 TeV).
The LHC is located at least 6,000 km from where I am, and may cause a 7 TeV collision.
Cosmic rays hit a few hundred km above my head, with collisions of energy greater than 1,000,000 TeV.
Every second.
For billions of years.

I also find a problem with the first sentence of the article...
It is possible.
The latest thought about new universes was that a "magnetic monopole" was needed. This would be a magnet-like particle, but with only one pole (magnets normally have both north and south, unlike electrons, which have only one type of charge). If one is produced, then it could in theory create a new Universe.
And of course it's possible. Perhaps our own Universe came into being from such a black hole as well. The Big Bang was in actual fact nothing more than the explosion of a gigantic black hole.
If the LHC can make a micro black hole, they're supposed to evaporate in something like 10-56th of a second. This is shorter than plank time - the shortest time for an event. My interpretation is that it's something that can't be built.
But let's say that it does create one. They'd have very little mass, and so could only grab something else if it struck it head on. Most of the space between atoms is empty to something the size of any black hole the LHC could produce. And, it's moving quite fast, so it will most likely head in a nearly straight line through the ground (the LHC is underground), and out into space, never to be seen again.
Also, there's conservation of mass/energy. Even if evaporation creates an explosion, it can't be bigger than the mass/energy that went into it.
Create a Universe? It looks as if we'd never know it.
It's theoretically feasible, though impossible to prove. Any universe created by these quantum black holes would probably collapse in on itself fairly quickly, given the lack of stability involved.

Ok, I'm not a conspiracy theorist and I do have faith the LHC won't destroy the earth, BUT?
