These are good questions. Anyone have any ideas?
You are a good example of a stupid scaremongerer. Anyone know when he'll f**k off?
Consider why we don't see media attention about the possibility of the atmosphere suddenly igniting and killing anyone. It's a possibility, after all. Some things which are possible have such a vanishingly small chance of happening that they are not worth worrying about. Time and effort has been committed by those capable of demonstrating the vanishingly small chance of LHC eating the universe with black holes. Uba is one of the scaremongerers who ignores this because he doesn't understand it. Most people here think he's a bit of a c*ck muncher (sorry, I don't mean to insult any real c*ck munchers reading this)

1) Is there a possibility that the LHC can create a black hole on October 21, 2008, which is when the collisions begin?
Yes. It is a very small possibility, but yes.
2) Hawking Radiation hasn't been confirmed and yet their going ahead and doing this? Even with odds in favor of people who say no black holes will form, there is still a minimal chance correct?
Yes. Hawking radiation is very likely to be true. Yes, there is still a chance.
One notable fact is that even if a black hole is
formed and doesn't
evaporate, it presents a minimal danger to the earth.Review of the safety of LHC collisions

To add slightly to what MjolnirPants said, IF a mini black hole was created AND IF it did not evaporate because Hawking Radiation was not correct, it would still have almost no mass, which means its gravitational pull would be incredibly weak. Also, its radius would be so small that it would be an almost invisible target. I remember doing some super rough calculations (with just some simple undergrad equations a few years back) and its radius would be on the order of 10^-50m. So there would effectively no target (and thats assuming the entire center of mass energy is converted to the mass of the black hole.)
So, like was said, the risk is non zero, but so small its pretty much not even worth mentioning
