Those anxiously awaiting the restart of the most complex machine ever built on earth will have to wait a little longer, as CERN today announced they were pushing back Large Hadron's restart to September.
It was previously hoped that the LHC's tunnels would be down to near absolute zero in time for a summer reactivation, but September is now the goal to accommodate further safety features and inspections. Experiment data will be in eager physicists' hands by early 2010 by the new schedule.Those anxiously awaiting the restart of the most complex machine ever built on earth... more

When the LHC first went down, it was believed that repairs could get the system up and running by April 2009. Then we saw repairs pushing the timeline back to summer 2009. But now, CERN has arrived at a fork in the road regarding LHC repairs.
According to spokesperson James Gillies, the complicated repairs can be simplified into modest Plan A and Plan B approach.
Plan A is a quick and dirty fix, getting the particle accelerator online as quickly as possible (late summer 2009) at the cost of operating at lower power. In this scenario, 3 of 8 pressure relief-system segments are replaced (only the broken ones) with the other 5 getting upgraded at unsaid maintenance dates in the future.
Plan B is the more extensive but also more delayed approach, requiring the complete redesign and replacement of the LHC's entire pressure-relief system. Under this scenario, the LHC wouldn't go online until 2010 at the earliest, though at that time the system could operate at full power.
As of right now, the team is moving ahead with Plan A in the interest of getting data as soon as possible. Since we have absolutely no way of knowing which course of action is best, we'll just support whatever the crazy physics geniuses decide.When the LHC first went down, it was believed that repairs could get the system up and... more

A federal judge in Hawaii has dismissed a lawsuit trying to stop the world's largest atom smasher.
U.S. District Judge Helen Gilmor says in a ruling issued Friday that federal courts don't have jurisdiction over the Large Hadron Collider in Europe, near Geneva.
Two Hawaii residents sued because they feared the machine could create black holes or other phenomena that could destroy the planet.
Most physicists say the collider is safe. It started low-power operation Sept. 10 but suffered malfunctions and will be shut down until spring.

The Hadron Collider has an electrical problem.
The machine that was predicted to recreate the big bang and possibly end the world over a week ago is being put to rest for the next two months. This ruins hope that the machine would be up and running for its inauguration in October.
The actual problem, according to physicists, will only take a day, maybe two days to fix. It's just some faulty wiring, contained within a 2-mile area.
However, the collider is kept at -456.3 degrees Fahrenheit (-271.3 degrees Celsius). The collider has to be warmed up so that workers can enter into it, fixed, and then cooled back down. The whole process will take 2 months.The Hadron Collider has an electrical problem.

The successful start-up of the Large Hadron Collider represents not just a huge victory for particle physics but also a victory for Europe. Once upon a time there was a brain drain from Europe to the U.S. – not only Albert Einstein in the 30s but also Wehrner von Braun in the 40s (”Once the rockets are up who cares where they come down? That’s not my department, says Wehrner von Braun”) and all the way through the 1970s, 80s and 90s.
But today? There’s no doubt that Europe – especially CERN — is the center of the science world. The Europeans took the lead in building the LHC, kicking in $6 billion. The US contribution? Just over $500 million, Alan Boyle reports at MSNBC.
Besides the LHC, there’s the ITER fusion research center in southern France and potentially another fusion project, the HiPER laser-fusion facility.
Meanwhile, in Washington, politicians yanked support for ITER and ripped $94 million out of physics research. Some of the funding has been restored but many positions were lost.
Michio Kaku points to the cancellation of the planned Superconducting Super Collider in 1994.
“Let’s be blunt about this: There could be a brain drain of some of our finest minds to Europe, beause that’s where the action is,” Kaku said. “We had our chance, but Congress canceled our supercollider back in 1994. We’re out of the picture. We can basically tag along after the Europeans, begging them for time on their machine — but really, the action is in Europe now.”
What will the US role be for the next major project, the International Linear Collider? The US is supposedly interested but it will have to compete with newly rich nations like China and India that boast serious scientific minds of their own. Beijing just hosted an exploratory meeting on hosting the ILC.The successful start-up of the Large Hadron Collider represents not just a huge... more

SCIENTISTS are trying to stop the most powerful experiment ever – saying the black holes it will create could destroy the world.
Dubbed by some the Doomsday test, it will be carried out next week in the Large Hadron Collider (LHC), located 300ft underground near the French-Swiss border.
The machine is 17 miles long and cost £4.4billion to create.
When its switch is pulled on September 10, this atom-smasher will become a virtual time machine, revealing what happened when the universe came into existence 14 billion years ago.
New particles of matter are expected to be discovered, new dimensions found beyond the four known, as scientists re-create conditions in the first BILLIONTHS of a second after the Big Bang.
The atom smasher ... the 17-mile-long machine that some fear will destroy our planet
Experts even predict that millions of tiny black holes will be produced — baby brothers of the monsters gobbling up dust and stars at the heart of the galaxies.
That is why boffins are now trying to stop the project with a last-ditch challenge in the courts.
They fear the LHC experimenters are tinkering with the unknown and putting mankind — and our whole planet — at risk. SCIENTISTS are trying to stop the most powerful experiment ever – saying the black... more
