The end of the world??

There is a currently ongoing experiment with CERN in which they'll use a particle accelerator to create what we believe to be the conditions of the universe immediately after the big bang by colliding two speeding particles together. Well, that's the simplified version of it, anyway. There's no need to be concerned for your safety, however. Experts have assured us that the experiment is quite safe.

There are no scientist doing what you described. Last week the news reported on the completion of the CERN supercollider. Tis will accelerate protons to close the speed of light and they will collide with each other. From this, the scientists can learn about the forces of nature that keep the atoms together. This sort of thing has been done for decades. The difference now is that the collision will occur at higher energies. The protons that collide are so small and there are so few of them, that you wouldn't even be able to see them with the naked eye.

No black holes are being created and not atoms being smashed. These rumors remind me of that game, where you sit in a circle with a bunch of friends. You say something to the person next to you, and then they do it to the next and then the next. By the time it gets back to you, you don't even recognize what they are saying.
