@EvilSOB: It seems that you misunderstood me a litte. My definition of a black hole, is EXACTLY the same as yours (an object with so much gravity that even light can't escape).

And I do know that antimatter is not the same thing as black holes. But I did read and hear that small, unstable black holes are going to be created in the LHC. That's why some people think that because of the LHC we are all doomed. (Funnily, the first run with first energy is planned for 2012, which may make them think they are right :D).



Then black holes would be impossible, but this would also mean that Einsteins theroy of gravity is wrong.
