CERN

Late in September, CERN disclosed that a faulty electrical connection had knocked the collider offline till next spring. Now, it looks like it will cost upwards of $21 million to get the collider operational again.

Problems continue to plague the world's largest particle collider, as physicists today disclosed that a faulty electrical connection has knocked it offline until next spring.

Scientists completed the first tests of the Large Hadron Collider on Wednesday morning, far more quickly than they had expected. But it will still be months before the first experimental data in the search for elusive subatomic particles starts to flow.
