Large Hadron Collider (LHC) Tests

Post by JFK »

Hunt for the God particle

LHC — short for Large Hadron Collider (the most powerful particle accelerator ever built)

Place: Cern, Geneva, Switzerland

Cost: $8 billion project
$6.7 billion machine

Arguably the largest and most complex science experiment ever constructed.

Physicists are excited by the LHC. It will be the world’s most powerful particle accelerator, colliding protons into each other at an energy of 14 TeV (tera-electronvolts), giving access to physics at an energy scale about ten times higher than has been open to exploration so far.

A proton travels around a 27-kilometer ring (deep underground) at nearly the speed of light. Along with a bunch of other protons, it passes through the hearts of each of a series of detectors more than ten thousand times per second.

Then, on one pass, it slams into a proton coming from the other direction. The collisions will occur 600 million times every second, producing a spray of subatomic debris.

No one really knows what the machine will give birth to. But the equations suggest that some weird stuff could be just around the corner — maybe "dark matter," the invisible stuff that seems to hang around galaxies. Some theories say it is possible the collider will cause miniature black holes to momentarily appear.

Some people at the lab think that these projects are pushing the boundaries of what can be achieved by humans: financially, politically, and organizationally.

"The size is amazing," "It's actually in an underground river. We had to sink liquid nitrogen probes and freeze the river around it to lay the concrete structure down. [It was a] massive civil engineering project. And the detector itself dwarfs anything I've seen. It's like a five-story building. It's ridiculous."

The underground complex crosses the borders between France and Switzerland, but the majority of it is located in France

FACTS

- Global participation: More than 7000 scientists from 85-plus countries are involved in the LHC collider (They include some 750 scientists from US universities and national laboratories)

- Planning started 20 years ago, the first applied research began 15 years ago

- Length 27km long (16.7 mile)

- Weight 38 000 tonne collider

- Most located between 50 and 150 meters (165 and 490 feet) below the surface of the Earth. Some parts are down shafts that reach 300 feet into the earth

- The magnet is the size of a house, and can store enough energy to melt 18 tons of gold

- The electromagnet is almost 2,000 tons (That's the weight of five jumbo jets)

- A complete sector of the machine was being prepared to be cooled to its operating temperature of 1.9 degrees above absolute zero, which is colder than outer space

- 120 MW power and 91 tonnes of liquid Helium to operate

- Traveling in a vacuum, the beams will approach the speed of light, making 11,245 circuits a second. Their acceleration will require roughly the energy that it takes to power Geneva.

- Once operational, the LHC is expected to have a lifetime of about 15 years

The New York Times and International Herald Tribune announced the intentions of a global group of physicists to re-create the environment of the early universe so they can better understand the Big Bang. After a hundred years of theory, discussion, and lab tests, the time has come to test results at a higher level.

Nobody seems to know exactly what will happen when LHC begins operations in May 2008? I guess we need to wait and see…

Just one question: what does the article have to do with a "god particle"?

yeah.. welcome JFK. i'm convinced this has already been posted before :wink: ... all that blurb and not one mention of the, entirely theoretical, higgs boson... (the 'god parcticle' being referred to here).

still, going to be a big day when they run the first test...

Nice read.

The "god" in the title was to draw you all here as we all know how this forum reacts to religious posts. Think of poop and flies... rather effective imo.

omw this is some hectic shiznit. what if they pull it off, and use it as a weapon of mass destruction? throwing SA rugby teams into it whenever they go to france again? 8O

I did not dump all the data about this 'science experiment' as it was too large. Anyway thanks for the interesting comments…

mount that technology to a machine gun to fire out black holes instead of bullets and we all gone, black hole warfare...i think that will be used for destructive purposes eventually...its the nature of man that some use it for evil...

what can I say. with a post like that, it looks like you will always bring the forums something interesting to talk about. welcome.

its an interesting article and I can't wait to hear what they discover. i firmly believe that within the next 100 years man kind will manage to travel to the nearest star, and it is through projects like this one that will help make that dream a reality

Agreed, interesting read ....

I can see people getting their knickers in a knot somewhere given that they build this huge machine and they are not sure about what results to expect from the experiment.

They maybe need to wordsmith their stories a bit ... else we will see the usual picketing with words such as "Armageddon", "Down with science" and "Hello mom!" on the placards ...

...there are already… :onfire:

The problem is that you can't predict what's going to happen - nothing like this has ever happened before (so how do you simulate it?). It could be that nothing harmful happens; on the other hand I wouldn't discredit the destruction claims very quickly.

I don't think that the planned experiments will be stopped though - definitely a case of "curiosity killed the cat".

even though the cat knows that this curiosity may kill me_ would he still have gone on...

very interesting i must though as so many have

i would like the experiments to go ahead. columbis sailed into unknown territory and look what he discovered.
