Theoretical, its all that it is. We don`t know much its all about theories, calculated from observations and theories from many scientific minds.
In this case we can`t afford to be wrong, one of the first things that came to my mind was the law of relativity.
The gravitational force of a black hole, even on a small scale.
We have heard about gravity waves as from Einstein@home, we can`t even be sure that time is constant. Because we are always in the moment, we don`t know if time is slow or fast we are all on earth in it.
Think about the effect from black holes, bending of time that is chilling.
If a black hole is formed, even on a microscopic scale.
Could that cause a time warp effect?
If that would happen, would that cause the black hole to stay open longer than predicted?
If such a time warp effect would occur then the event would have more time to accumulate, and perhaps even grow.
The thing is, we can`t be certain as it all is based on theories.
We also don`t know what other effect might appear when it comes to spacial dimensions and what effect that might have on such event.

Well, this is a theory like all others. But it makes us think, what might happen.
And is it safe to gamble on such a big scale?

I need more information, anyone?

Yes, we certainly need a lot more information. And that is why the LHC has been built!
You are right that black holes warp time, but remember, even if the LHC can produce a black hole, it will be an extremely small one that wouldn't even warp time a millimeter away.
The LHC simply hasn't the energy to create a large black hole, that much we know.

Yes, it is safe * , because even if the Energy used to build a black hole at LHC's absolute maximum power levels, it remains effectively and literally - small. And it's not a gamble, they just take known parameters and push the previous limit further back with increased power and increased detector capabilities. Additionally, I can't imagine them firing up the LHC for a full-power drive at the very first runs, they'll likely increase total power slowly, step-by-step (after all, it's a very complex machine and a very expensive, unique science tool - they'll treat it friendly ;) )

If it ever succeeds making one, we'll have the most short lived, most tiny "black hole" in the Universe. So tiny, a butterfly could go right through it and destroy it.

IF they ever build a 300000 Mile, 1E20+ times more powerful accelerator around the orbit... one can start thinking whether that's a smart idea building into terrestic orbit rather than in deep space for safety reasons. But that's not going to happen too soon.

To build a self-sustaining black hole, you'd need more Energy than this entire Planet produces in a thousand years at current rate. With existing tech, we couldn't even build a tiny one the size of a PingPong ball - which wouldn't be self-sustaining at all even if we tried hard... if one existed on earth, it would simply blow apart due to lack of Gravity or comparable stabilizing force.

Bottom line :
High numbers often sound impressive, but in the really big scheme of things (space, e.g. black holes) what LHC does is absolutely microscopic - and that's an optimistic description (it's actually less than that - far far less)

Someone (years ago) on the topic of AntiMatter once calculated, that all Accelerators combined, operation sustained at maximum power levels, could at best produce approx. 50mg of pure AntiMatter per year. Actually lucky that is, plus the enormous containment requirements (power-hungry electromagnetic forcefields and space/weight constraints) to stabilize the samples that prevents anyone from building an AntiMatter Bomb, apart from the insane production costs... (that would be a Thermonuclear bomb on steroids and bad news for the planet)

* Safe means that no known, harmful radiation will exit the superstructure.
For all I know, the radiation or particles are extremely short-lived and either near-instantly absorbed by the detectors or no later than the surrounding superstructure itself. And if unknwon particles or related radiation actually makes it through hundreds of meters of dense steel, concrete and rock - it is expected to simply pass through all known, living organisms without being absorbed at all, which makes sense in my mind.

PS.
Building a Tesla grid loaded with 16 TeraVolt would be a more risky business - apparently "funny" things start to happen around extreme electromagnetic fields when exceeding certain limits... but that's another story.

Well given that Cosmic Rays have more energy and we are still here ... I would not worry. And if some \\\"strange\\\" things happen and the earth is destroyed well \\\"It\\\'s been fun!\\\"

And eventhough a big black hole swallows us in 2 seconds, it might still last 10.000 years for us because of the time distortion! :-D
