Oh Noes! Musta been a microblack hole!

That's the only reason that the universe didn't collapse down on itself, the micro blackhole stopped the machine from creating even more micro black holes, which would have destroyed everything!

Karma is a cruel and ironic mistress!

GENEVA - The world's largest atom smasher  which was launched with great fanfare earlier this month  has been damaged worse than previously thought and will be out of commission for at least two months, its operators said Saturday.

Experts have gone into 17-mile (27-kilometer) circular tunnel housing the Large Hadron Collider under the Swiss-French border to examine the damage that halted operations about 36 hours after its Sept. 10 startup, said James Gillies, spokesman for CERN, the European Organization for Nuclear Research.

"It's too early to say precisely what happened, but it seems to be a faulty electrical connection between two magnets that stopped superconducting, melted and led to a mechanical failure and let the helium out," Gillies told The Associated Press.

Gillies said the sector that was damaged will have to be warmed up well above the absolute zero temperature used for operations so that repairs can be made  a time-consuming process.

"A number of magnets raised their temperature by around 100 degrees," Gillies said. "We have now to warm up the whole sector in a controlled manner before we can actually go in and repair it."

The $10 billion particle collider, in the design and construction stages for more than two decades, is the world's largest atom smasher. It fires beams of protons from the nuclei of atoms around the tunnels at nearly the speed of light.

It then causes the protons to collide, revealing how the tiniest particles were first created after the "big bang," which many theorize was the massive explosion that formed the stars, planets and everything.

Gillies said such failures occur frequently in particle accelerators, but it was made more complicated in this case because the Large Hadron Collider operates at near absolute zero, colder than outer space, for maximum efficiency.

"When they happen in our other accelerators, it's a matter of a couple of days to fix them," Gillies said. "But because this is a superconducting machine and you've got long warmup and cool-down periods, it means we're going to be off for a couple of months."

He said it would take "several weeks minimum" to warm up the sector.

"Then we can fix it," Gillies said. "Then we cool it down again."

CERN announced Thursday that it had shut down the collider a week ago after a successful startup that had beams of protons circling in both clockwise and counterclockwise directions in the collider.

It was at first thought the failure of an electrical transformer that handles part of the cooling was the problem, CERN said. That transformer was replaced last weekend and the machine was lowered back to operating temperature to prepare for a resumption of operations.

But then more inspections were needed and it was determined that the problem was worse than initially thought, said Gillies.

The CERN experiments with the particle collider hope to reveal more about "dark matter," antimatter and possibly hidden dimensions of space and time. They could also find evidence of a hypothetical particle  the Higgs boson  which is sometimes called the "God particle" because it is believed to give mass to all other particles, and thus to matter that makes up the universe.

Smaller colliders have been used for decades to study the makeup of the atom. Scientists once thought protons and neutrons were the smallest components of an atom's nucleus, but experiments have shown that protons and neutrons are made of quarks and gluons and that there are other forces and particles.

The LHC provides much greater power than earlier colliders.

Its start came over the objections of some who feared the collision of protons could eventually imperil the Earth by creating micro black holes  subatomic versions of collapsed stars whose gravity is so strong they can suck in planets and other stars.

Excuse me?  Am I missing something here?

I admit I was paying attention to Mary-Elizabeth instead of the physics class lectures (sorry no pics of either, but my memories of M-E are crystal clear) but just how do you get colder than outer space?

stay safe.

As I recall, and it's kinda fuzzy, it goes something like so:

Outer space is cold, and has very little matter, but has all kinds of radiation zipping throuh it.  (light from stars, old TV broadcasts and such), and since one can't really measure the temperature of a vacum (nothing) You have to park some matter there and measure the temp of the matter.  (even if that matter is the thermometer itself)  As soon as you put matter there it gets hit with some of that zipping radiation and gets some energy, thus it warms up a tick.  (we're assuming here that the meter was cooled to 0K before the experiment, and there's no waste heat from your spaceship.  Thusly since outer space isin't really empty, only mostly empty it's a tick warmer then absolute zero.  (defined as the temperature whare all molecular motion stops.)

Of course my physics text has the words "Don't Panic" written on the front in large friendly letters so I might be a little off here.

Found this answer on a NASA website (so yes, it's probably part of a deep, dark, government conspiracy...)



The Question
(Submitted March 01, 1998)

All I wanted to ask you is that if we put a thermometer in Space with no other light or heat source around and absolutely no background radiation there, what would it read? Would the temperature be really cold or what?

The Answer
Yes, it would be really cold. Temperature measures the energy per "degree of freedom" (i.e. way something can move) of whatever molecules happen to be around. So, it it becomes so cold that the molecules stop all together, then this is the "absolute zero" temperature. On the Celsius Temperature Scale (i.e. water freezes at 0, and boils at 100) this takes place at -273 degrees C.

We usually use the Kelvin temperature scale, where Zero Kelvin is this "absolute zero" temperature -- or -273 degrees C. Water freezes at +273 Kelvin and water boils at +373 Kelvin.

If we put a thermometer in darkest space, with absolutely nothing around, it would first have to cool off. This might take a very very long time. Once it cooled off, it would read 2.7 Kelvin. This is because of the "3 degree microwave background radiation." No matter where you go, you cannot escape it -- it is always there.

for Ask an Astrophysicist



A little more reading and I've discovered that this is the radiation that Arno Penzias and Robert Wilson first discovered in the 1960s. No matter where they pointed their antenna, they found the same level of background radiation. It's constant over the whole of the sky, and is seen to be the lingering vestiges of the Big Bang.

Neat what you learn on a Sunday morning.

Is that akin to letting the smoke out of an electrical device? cheesy

This is actually not that big of a deal.

It's just a wire connection issue, and the only problem they have to deal with is heating up the device so that the person that goes down to fix it doesn't instantly turn into a popsicle and then cooling it back down when finished.  So, it's a time consumer due to the temperature issue only.  If it wasn't for that, this would be a quick fix.

That sort of heating and cooling must be done sloooooooooowly, too.

Otherwise, you get a big, expensive, CRACK!

My worry has been the opposite: that all these particles colliding will accidently create a new universe, which has been generally considered to be a bad idea.  laugh

Depends. In this new universe do I get to be rich, have the hot triophy wife, and post '86 full autos and hand grenades for cheap? If so, I say lets get to it!  grin
