Large Hadron Collider
According to an essay in the New York Times, the scientists are trying to explain why the collider, the worlds largest particle accelerator turned on with great fanfare in September 2008 by the European Organisation for Nuclear Research (CERN), was closed down for major repairs just over a week later. The 3 billion-euro collider was supposed to track down the Higgs boson, a subatomic particle believed to have given mass to the universe milliseconds after the Big Bang created it some 15 billion years ago.
Physicists think this minuscule speck of matter, if ever found, could explain the mysterious code at the origin of the physical world.
I wonder what the real problem was why they shut it down? I did not see any new coverage about the shut down.Respectfully,
Mr. Terrence

Do you know what the LHC is? if not: http://en.wikipedia.org/wiki/Large_Hadron_Collider

Particle physics yay...just the thought gives me a hadron.

I thought they were looking for Quarks.
Isnt that what they do @ FermiLab?My IP >> 127.0.0.1 Hack Away!!

Reading that Wikipedia article, it appears that it has had a shaky life since the construction began.

Manufacturing defects in the magnets, for one. And it isn't as simple as climbing down into the tunnel and fixing them. You have to warm the tunnel section you need to do work in up (a few weeks process), fix the magnet, test it, and then cool the entire thing back down. Plus they found these issues in several magnets - once you find a problem in a multi-billion dollar project as big as this, you double check everything.
Think about it this way - cars are some of the most complex machines that we mass produce. And cars break down all the time. Everyday I see a broken down car or a mechanics shop full of cars - and that's something we've been building for decades. The LHC is probably the most complex large scale machine on the planet (and definitely the most complex particle accelerator) - it's bound to break down a few times.

Also there was quite some press coverage on the shut down, maybe you just missed the coverage it was not nearly as exciting as the startup itself. Everyone was expecting a big bang and all we got was bit of hot air

There are theories that the LHC could create microscopic black holes. But they are most likely to evaporate.

Yes, the LHC destroying the world is old news, and sadly the same questions are raised about existing supercolliders. Some people just watch too much Star Trek.
On a more serious note, I have seen one of the detectors up close and been down in the tunnels of the LHC. It's a pretty impressive machine, and the scale of the thing isn't done justice in pictures. The countryside there is also very beautiful. It's a good place to check out, if you're in the area and have a friend who can let you in.

Fermilab
If you're stateside and interested in this kind of thing, Fermilab in Batavia, IL is a great place to visit. A group of friends and I enjoyed going out there for a tour of the accelerator. Not as powerful as the LHC will be, but it's working and still producing results.

But I alone realised that the experiment we were doing was extremely dangerous, and would trigger a chain reaction that would cause the entire planet to instantly collapse into an ultra dense particle, about the size of a pea.

You thinking about mud would give you a hadron.
I've always been a bit uneasy with what they're doing there. I think a very fitting end to our existence would be poindexter nerdy scientists trying to recreate the origins of the universe and messing around with black holes. Yeah, that's what we need forsure.

Unfortunately, yes. They have a visitors center at the main CERN facility, but the LHC ring comprises several sites, and each are a sight. Because much of the collider and detectors are assembled above ground, there are massive warehouses with gigantic holes at one end that lead down to the tunnel (and we're talking about 100 meters deep here...).
Don't tell!

I hope them good scientists who built that facility offset their carbon emissions generated from that project. Doomsday projects must at least be carbon neutral.

They teleported the Gordon to Xen. So they are preparing for his return:

Excellent image!
If anybody is interested, you can see pictures of CMS (the experiment that I saw) here. There are a couple people in some of them which gives you a good idea of the scale of the thing.
