The chance of a black hole being made are small as I remember it. But you can always quote the dangerous things that probability says could happen. it could also make something called a strange particle, which has a different quark spin configuration. Those have a lower ground state energy than normal matter, so it could cause a catylyst that lets other real matter near it to tunnel down into that potential well if close enough, and form MORE strange matter, which can have a run away effect and cause the whole Universe to be destroyed. I dont make it up. But the chances are so infinitesmillay small, better not to spend any of your worrying on it.

(Neat thing to note, that same matter, strange matter, is believed to be down in the core of neutron stars as well, POSSIBLY. And if it is, they think coloumb interactions keep it far enough away from other matter to avoid tunneling and causing that run away effect.)
