Indeed, what's up with that. They've been repairing it for a year now.


So when they finally turn it on again and maybe one tiny part dies we'll wait again for a year so they can repair it, re-calibrate it and re-establish all temperatures, vacuum and so forth...


Damn expensive toy to just sit there and collect dust.

Seems it will be fired up again mid-November. And full power for Christmas, what a perfect time for armageddon.

"This fault was caused by nothing more technical than a bad soldier joint!" Gillies told Swisster, an oversight that lead to a repair bill of some 40 million Swiss francs. The estimated cost of the entire project is thought to be in the region of 10 billion francs.

Possibly ROHS problem ;)

There is more to it. I have read in a paper that says that it will *not* run at design power any time in the near future, if ever. It stated that the scientists will have to settle for a bit less energy in their experiments. That would mean the quest for finding the Higgs may well leave some ehh openings... Not that I think the Higgs even exists. CERN is just a social project for scientists, and creates jobs for all sorts of techies. Sort of a black hole for money :-) Talking about black holes... well, Bell accidently got the telephone working, maybe some other bad joint (soldering or other wise there) will ... well imagine, no more Usenet...? No more republican party, no more national debt, no more ice cream, no more taxes. hehe

God's preventing it from being built, because it will make a black hole, which will immediately fall through the floor, almost to the other side of the planet, bounce back, and so on, consuming Earth's matter as it goes, until the whole planet is gone.

Hope This Helps! Rich

Bell did not invent the telephone. Meucci did.

Where does it get sent?

Answer that and you can complete all the equations... At least those that involve these three dimensions.
