The LHC going online

Not grams definitely not grams. It costs $300 billion per milligram of antimatter, and it would take 2 billion years to produce a single gram if CERN was working at full capacity 24/7/365.

As for QSs being produced in the upper atmosphere, is there even any evidence for that? If there were QSs being produced, what would make them collapse? (I'm sketchy on these details) Would it be hawking radiation - though that ain't proven yet, or would it just be unstable?

Imagine what kind of technology we can create and use after studying the info from the Accelerator.

Thats probably oneof the questions they are trying to answer withthis device.

[Boggy1 45]

Gah, delayed again. It's now gonna begin prelimiary firing in September, a year after it was schuduled too.

Hadron Collider relaunch delayed

The Large Hadron Collider could be switched back on in September - a year after it shut down due to a malfunction and several months later than expected.

Scientists had said they expected the

Doh. now we have to wait again.
Stupid magnets.

What a rip off!  I bet you can get it for a lot less at Wal-mart .

That thing scares me.

[LarksTonguesInAspic 28]

A recent news story said that it does indeed create black holes, that they are bigger than predicted, and last longer than previously thought... seconds, instead of milliseconds. No need to worry, they are supposed to travel away from the earth at the speed of light.

Swell. Now we're sending black holes out to other places. I suppose the neighbors aren't going to be very happy when they take delivery. Anyone know where I can get a Thumb-O-Matic, and a dolphin departure schedule?

[TwelveToneMusic 0]

So they claim to be able to direct black holes? What happens if they aim wrong, or whatever, and one shoots AT Earth?

[Odainsaker 2,137]

Wait a minute...another delay followed by another launch followed by another delay till another launch? Meanwhile, the same fears are being debated here yet again. Haven't we done all this before? Omigod Geordi, a chain of micro black holes from the LHC have created a warp bubble causality loop in the Space-Time Continuum!

[jon7985 3]

I hope they just fire the damn thing up, they couldn't mess things up worse than the US Congress is messing up the economy.

Are you suggesting there is no danger involved with the 'handling of black holes'?

I was responding to the comment by Odainsaker.

It did it!

This morning, after several delays, the LHC churned up to half its possible power at 7TeV. This record-breaking event sets the stepping stones for answers to some of the most fundamental questions of the Universe.

They telecasted the event (with five different webcams and a number of presenters doing interviews and voicovers) and you could also access copies of the terminal screens showing live energy readouts and raw data. To suddenly see both beams shoot up in energy was astounding. They had stable beams for over three hours. 

Probably the most incredible thing was that they recorded half a million events; while the thing was colliding new and exotic particles were being torn into existence.  I just find that amazing. 

 

 

Cern LHC sees high-energy success

Europe's Large Hadron Collider (LHC) has produced record-breaking high-energy particle collisions.

Scientists working on the European machine have smashed beams of protons together at energies that are 3.5 times higher than previously achieved.

Tuesday's milestone marks the beginning of work that could lead to the discovery of fundamental new physics.

There was cheering and applause in the LHC control room as the first collisions were confirmed.

 

LHC EXPLAINED LHC guide in graphics and video

These seven-trillion-electronvolt (TeV) collisions have initiated 18-24 months of intensive investigations at the LHC.

Scientists hope the studies will bring novel insights into the nature of the cosmos and how it came into being.

Many of them have described Tuesday's event as the beginning of a "new era in science".

But researchers caution that the data gathered from the sub-atomic impacts will take time to evaluate, and the public should not expect immediate results.

"Major discoveries will happen only when we are able to collect billions of events and identify among them the very rare events that could present a new state of matter or new particles," said Guido Tonelli, a spokesman for the CMS detector at the LHC.

"This is not going to happen tomorrow. It will require months and years of patient work," he told BBC News.

The LHC is one of the biggest scientific endeavours ever undertaken.

WHAT IS AN ELECTRON VOLT? Charged particles tend to speed up in an electric field, defined as an electric potential - or voltage - spread over a distance One electron volt (eV) is the energy gained by a single electron as it accelerates through a potential of one volt It is a convenient unit of measure for particle accelerators, which speed particles up through much higher electric potentials The first accelerators only created bunches of particles with an energy of about a million eV (MeV) The LHC can reach beam energies a million times higher: up to several teraelectronvolts (TeV) This is still only the energy in the motion of a flying mosquito But that energy is packed into a comparatively few particles, travelling at more than 99.99% of the speed of light

Housed at Cern (the European Organization for Nuclear research) in a 27km-long tunnel under the Franco-Swiss border near Geneva, the LHC successfully collided particle beams travelling at close to the speed of light.

The expectation is that previously unseen phenomena will reveal themselves in the resulting debris, with a key objective being the search for the much talked-about Higgs boson particle.

This is thought to have a profound role in the structure of the Universe, and would enable scientists to explain why matter has mass - something which, at a fundamental level, they have difficulty doing at present.

Cern's director general Rolf Heuer said: "It's a great day to be a particle physicist.

"The LHC has a real chance over the next two years of... possibly giving insights into the composition of about a quarter of the Universe."

Take two

The LHC broke down shortly after its opening in 2008 but, since coming back online late last year, has gradually been ramping up operations.

Two proton particle beams have been circling in opposite directions in the magnet-lined tunnels at 3.5 TeV since 19 March.

Having established their stability, these beams were allowed to cross paths and collide.

This 7 TeV event, which took place on Tuesday at 1200 BST, was the highest energy yet achieved in a particle accelerator.

The LHC's four major experiments - its giant detectors Alice, Atlas, CMS and LHCb - have now begun to gather their first physics data from the collisions, a development that Cern described as an "historic moment".

The LHC's detectors are examining the debris from the collisions

"This is new territory," said Professor Tonelli.

"If you want to discover new particles, you have to produce them; and these new particles are massive. To produce them, you need higher energies. For the first time [on Tuesday], we will be producing particles that have energy 3.5 times higher than the maximum energy achieved so far.

"This is why we can start the long journey to make major discoveries in identifying a new massive state of matter."

It's great to hear of this progress. Though I don't pretend to really understand much of it, I gleaned enough from my physics lecturer to be quite enthused by the potential for learning the LHC represents. It, and the still far way SKA (It's not just SC4 dodging acronyms), are probably amongst the most groundbreaking scientific projects any of us will live through. Bring it on I say

Whoo. Go Science.

So we are all still alive then?

We are.......for now. The Collider actually started the earths core turning in on itself, and in a matter of weeks, the earth will turn inside out and we will be trapped and will be turned into molten masses.....or not 

[Korot 6]

How high are the odds that Tuesdays physics class will be about this?

Anyway, it is a good thing they finally got the thing to work.

Now that they have successfully spend gazillions of Euros on this, the nice high-speed recorder output will keep them busy for generations examining the outcome.  I don't know whether or not the results will justify the time and money spent, but it is gratifying to note that pure research funding is available on such a massive scale. 

Since it was only running at half power, what can we expect when they run it up to full potential?  My understanding of this device is that it has very limited useful life, so I hope they get on with it soon.

I certainly hope they will find away around the c barrier among the results they get.  New physics is long overdue, so now there is hope that some things may get resolved and new stuff found.

[Boggy1 45]

The LHC does have a shelf life, but only because the longer it runs, and the more collisions they do at 14TeV, then the less results will get back in the long term. Therefore, the amount of new science and research will decline. The only way to get around this is to upgrade the LHC to having higher energy or luminosity levels.

Hopefully, once they get to 14TeV, we will eventually discover the Higgs Boson (amongst other exotic particles), which will be a breakthrough in science on par with the discovery that the Earth orbits the sun. It will confirm our entire understanding of the Universe so far; though, and we hope, its discovery will lead to thousands more questions we can search for the answers for.

And no, they won't get around the c barrier with the LHC. Unfortunately, the speed of light is one barrier that can't be broken.

The collider itself will have a shelf life.. However, the accelerator and cooling systems can, and will probably be used, to accomodate other researching devices and microscopes as many accelerators have been turned (or even recently built to become) into huge microscopes several times more powerful than electronic microscopes.

Never say can't in science.  It is just a problem that can be changed into an opportunity seeking a solution. 

Do tachyon's exist?  If so, how does one detect them?

Are you sure it wouldn't be a tachyometer?  Your answer is circular, and should be met in the LHC with a proton/anti-proton collistion at 14TeV.

[Boggy1 45]

Maybe. I'm wondering how on earth you would ever be able to detect a tachyon, considering they are by definition unable to travel below c. I don't think it would even be possible to detect them. They'd be moving in both time and space.

[Easy Bakes 253]

They can dectect nutrino's  but  i think tachyons are a more high energy particle.

Dang i noticed i spelled Obvious wrong too.
