CERN, LHC and Black Holes - or: What has happened and what has not (yet) happened

Today the CERN launched its largest experiment yet: After 15 year of planning and a 6 billion Euro investment just to build the 'Large Hadron Colider' (LHC) the scientists started two streams of protons. Those two streams are now being accelerated up to almost the speed of light, which will take several weeks. By the time these protons travel at target speed - and everything is still stable in the experiment - the scientists will lead them onto collision course. The aim is to get several protons to collide and produce an effect similar to what the scientists believe happened shortly after the Big Bang. So far, the machine has just been started and is now running on idle. There hasn't been any collision of protons yet.

But there is also a catch: When two protons collide there is a possibility that a black hole appears. Black holes are generally known as fields of immense gravitation, strong enough to suck everything in and crush the atoms of all matter. I've heard stories about black holes that could shrink the earth to the size of a tennis ball - please don't hold me responsible if this is not true. Since the whole process at the CERN experiment is rather abstract and 'normal' humans can't really describe everything I do understand fears about the nearing end of the world.

The CERN guys try to wipe away those concerns - obviously. Tiny little black holes appear everywhere in the universe - some even here on earth. And none of these has ever sucked in the earth because they only last for very short time.

Personally I'm confident on what the CERN guys say. I don't think the earth will disappear with a huge firework in October. If it does, it's been a big show.

Here's some clips and facts I found on the web today.





And this is what happens if something goes wrong on the experiment:
