Large Hadron Collider

Petit, superconductivity occurs at very low temperatures.

Also Lysander why do you care what this does if you can't even be bothered to do any research into it?

why on earth anyone would spend such money on a machine to collide invisible things is beyond me

Because smashing stuff is fun. It's one of those things we've been doing since we were children. Since smashing really large stuff is messy, it's better to smash small stuff.


I thought there was another thread that speculated that when they turn this thing on it will create a miniscule black hole that will instantly begin to "consume" and they figure about 1.83 seconds before the entire planet is devoured. Should be fun. We won't know a thing.

Yes, miniature black holes will be created, but no, they won't consume the Earth.

The one thing that just might consume the Earth is strange matter, but that won't happen until they start colliding lead nuclei in a few months, so we'll have to wait and see :p

Why do they need to make the magnets so cold?

Superconducting, pretty much no resistance meaning no heating when they pass 10,000+ Amps through them.

10,000 Amps @ 1 Ohm Resistance using I^2 * R = 100,000,000 Watts...

As I bet at room temp the resistance would be more than 1 ohm thats a hell of a lot of energy wasted :p
 
I am very interested in this,

read about the amount of data that thing is going to create makes it the largest IT grid in the world with 200,000 processors. Their IT department handles 14TB of home directories, 51TB of workspace, and the transfer of over 1TB per day between the sites :eek:
Oh, and on an average day, it will produce 40,000GB of data. good job they have 16 million gigabytes of tape storage :eek:

Not to mention some rather hot cables :p

the magnets arnt going to be absolute zero so theres gonna be some resistance

You don't have to reach absolute zero for superconductivity to occur, providing you're using the right materials. So no, there won't be any resistance.

From Wikipedia:

Superconductivity is a phenomenon occurring in certain materials at very low temperatures, characterized by exactly zero electrical resistance and the exclusion of the interior magnetic field (the Meissner effect).

Even near absolute zero a real sample of copper shows a non-zero resistance. The resistance of a superconductor, on the other hand, drops abruptly to zero when the material is cooled below its "critical temperature".

Did they not more or less invent the internet for their data processing systems way back when, not like we know it today but just as a kinda long distance network? Or have I been reading too much Dan Brown??

Kind of. No one really 'invented' the internet as such, though; Tim Berners Lee was responsible for many of the protocols and infrastructural elements of the internet but in reality it was developed by lots of different people and organisations.

That was something a documentory mentioned that I watched the other night, I always though the US universities & milittary invented it.. :confused:

Here is a link to the article I referred to.

I think it fires electrons at each other at massive speeds and this recreates the big bang from where they think the universe started. Something along those lines anyway.

So we're playing god? trying to re-create the universe... smooth.

Another theory is that it's going to turn the Earth into a black hole...

Oh, and it get's switched on on Saturday


(If any of this has already been posted, sorry, i'm too lazy to read the entire thread)

I drew this a while ago, I believe it to be the most accurate representation of what will happen when they finally begin testing the LHC in October 2008.

ITER is harmless. I don't know why they're doing so much trying to recreate the Sun here on Earth when we've got a perfectly good one 93 million miles away. We just need to capture more of it's energy more efficiently, that's all. Simple stuff. I'll draw up my plans this afternoon and have a working model next week.

Mind putting that into english?

There's a good article on it in the BBC Focus magazine issue #192. I get it on subscription so i don't know when you'll be able to find it in the shops. Excellent read though with some cool facts about it.

EDIT: From the magazine: 'When the LHC is at peak performance, 3000 beams each containing 100 billion protons will whizz around in each direction - storing energy equivalent to a 400-tonne train travelling at 150km/h (90mph). Such a beam could drill a hole through the magnets and put the machine out for months.'

It also says that if it detects a beam straying off course, they redirect it into a block of graphite shielded by 100 tonnes of concrete and steel to act as a 'bullet trap'.

Sounds like that could work as a weapon, if they could make it on a smaller scale, im thinking house or tank size not handgun size.

I have to wonder if there isn't an alternate reason for the lhc that most don't know, such resources going into the project seems a bit much for what it could tell us, unless they hope to somehow get the understanding and ability to manipulate mass (antigravity) or nano fabs to build us anything etc then i can't see how finding a few particles and possibility creating disaster is worth it, that's not to say im not amazed at it and think its a grand scientific project.

As for the alternate reason, i know that video posted was quite out there but couldn't there be another reason that some behind the scenes know, i have to wonder what a 27km ring of superconducting magnets with hundreds of billions of particles racing around will do to the space around it, mass creates gravity, these particles have mass and they're racing in a circle at the speed of light, and this has no effect on the space around it? i reckon there could well be unknown effects from this machine and not just particle wise, i suppose in time we will see, 2012 anyone?

the military 'invented' the internet, the web was invented at cern.
