This video is 5 years of CERN construction squashed into 5 minutes
Scientists will send two beams of particles around a 27km ring at 0.999999991 times the speed of light. Huge electromagnets will bend the beams, and collide one into the other.
The LHC project involves around 10,000 researchers and is based at CERN in Geneva, which is the world's largest particle physics centre.
The LHC represents the biggest scientific experiment of all time. By colliding tiny beams of protons researchers are hoping to recreate conditions in the Universe less than a billionth of a second after the Big Bang and uncover some of the universe's unsolved mysteries.
...an 11-nation team that has built detectors to pick up particles such as the as-yet-undetected Higgs boson - the so-called 'God particle' which could help to explain why matter has mass.
The music on the video is Ravel's Bolero and, perhaps, his own criticism of the piece may aptly describe this project as well...
It constitutes an experiment in a very special and limited direction, and should not be suspected of aiming at achieving anything different from, or anything more than, it actually does achieve. Before its first performance, I issued a warning to the effect that what I had written was a piece lasting seventeen minutes and consisting wholly of "orchestral tissue without music" — of one very long, gradual crescendo. There are no contrasts, and practically no invention except the plan and the manner of execution.

A handful of scientists will get to name some stupidly small particles after themselves; a few thousand science geeks will rub one out to footage of the machine starting; but for most of the human race, life will continue in the exact same damn way it did before the machine was built.

Well, I for one, am excited about this news. Regardless of whether or not they actually find the Higgs boson, this is an amazing step for particle physics.
Science is awesome.
A black whole will form over Switzerland and the whole world will implode!
Sweet!
Likely considerable advances in particle physics, which will no doubt prove useful in a wide variety of fields in the near future. In particular, the future of electronics lies in the world of particles, so it's not hard to imagine the LHC will play a pioneering role in the basic physics research that will bring each new generation of electronic technology.
I mean, viable quantum computers are pretty damn close to functionality, and we've just nailed the fourth fundamental circuit, so it seems like the door is being opened to even weirder stuff beyond. I think I'd probably shew considerable horror at a 10th-dimensional porn site, but the future is bright...

Eh, discovering about the planet you're on = handy times. The discovery of the Americas helped Western Europe become what it is today. Could probably do with discovering more about the more unmapped bits of the sea to see what we can take from it and use it for.
Discovering how the universe was made is sort of interesting, but not awfully practical in 'real' terms, at least to my eyes.

ALL science has a practical use, and all knowledge is valuable.
For example, Stephen Baxter(you being a Brit, you've probably heard of him) had this extremely FASCINATING idea about how the Higgs bosen, if found, could be used to harness a completely clean and extremely powerful source of energy. I have no idea how close that is to reality--Stephen Baxter, as I understand, is damned good about making sure his science is right--but it's an idea nonetheless.
The point is that anything could be useful, and dismissing it because we don't know one exactly right now is foolish and short-sighted, and I'd have thought you of all people would know better.

Our frontiers of knowledge are at polar opposites, the universe and our own brain, we've a pretty good idea of the rest.
The perception of both are highly influenced by each other.
My favourite stoned phrase is that, at one and the same time, we're an insignificant dot on the vast landscape [can it just be 'scape'?] of the universe while also being the most important thing in that universe, because we're 'me'.

CERN researchers have been threatened not to turn it on, because it might destroy the world. That amused me slightly because if it does destroy the world, no one can carry out those threats; and if it doesn't, the threats were entirely unwarranted.
(And considering they're not really doing anything nature isn't doing already, it's a baseless fear anyway.)

Untrue. What they fear is that a black hole would form that does not evaporate but instead "would increase in size" constantly. Destruction of earth would then be slow - plenty of time to carry out threats.

Not really. The lower-bound energy of the Higgs Boson predicted by the Standard Model without string theory is much, much higher than what the LHC is capable of putting out.
The energy level the LHC is capable of bringing proton collisions to is comparable to the lower-bound energy for the Higgs Boson under a few different interpretations of string theory (M Theory being one of them), however. As such, discovery of the particle would add weight to the viability of string theory research.
Failing to find it, aside from wasting massive amounts of money, would just lead to a call for a bigger smasher, most likely. One that (Oh gods, I hope) would not get funding.

Not really. Without the higgs boson, the standard model doesn't work (or rather, it only works in certain situations, which is a sign of an incomplete and incorrect model). If the higgs boson doesn't exist (and there's no point in going larger than the LHC to check, they'll either be the ones to detect it or it probably doesn't exist) then the standard model is fundamentally flawed. There'd need to be an entirely new theory to fix its flaws.
Untrue. What they fear is that a black hole would form that does not evaporate but instead "would increase in size" constantly.I very much doubt the people that are threatening violence are the type that even know black holes come in different sizes.
Destruction of earth would then be slowMy guess would be that collapse would be pretty fast; 20 to 30 minutes. The black hole would sink to the middle of the earth, and all matter would push itself into it at an increasing rate (due to momentum). Although I suppose conservation of angular momentum would have to keep some amount of matter outside the event horizon (spinning around the black hole, rather than falling in).
Anyone have anything better than a guess? A computer simulation would be nice.
I probably just haven't a good sense of the physics involved

"In this case, they will sink to the center of the Earth and begin devouring us all (at a rate of about one particle every few years)."

We really won't know that Hawking radiation exists until we've found a way to observe it, something we presently can't do. Hawking's formulation relies on a semiclassical interpretation of how Black Holes work, essentially requiring them to undergo black body radiation based on the amount of energy packed within them.
Any object that has a temperature above 0K (i.e. ANY object) radiated at a wavelength inversely proportional to the temperature. The human body has a temperature of around 310K, and so radiates at around 10um, or the far infrared (This is, incidentally, why pit vipers and IR goggles see a waveband around 10um). The sun radiates in the visible wavelengths because it has a temperature of around 6000K (which is why the human eye, and most animals' eyes are adapted to see in this wavelength range). Incidentally, empty space radiates in the microwave ranges (hence the Cosmic Microwave Background radiation) due to it being fricking cold, but not absolute zero (it's something really low).
Since temperature is in part reliant on the energy contained within an object, a black hole should radiate like a black body. This should result in a black hole that is not in the process of accreting matter losing its mass to Hawking radiation over time. This would, naturally take an obscene amount of time, in the case of a stellar black hole, and well beyond the lifetime of the universe for a SMBH, but for the near-infinitesimal black holes that could theoretically be created by the LHC, this evaporation due to Hawking radiation would happen very, very rapidly. Probably before the black hole even made it to the detectors and beyond.
At some point I'll go back and put together some calculations to back this up, but I (somewhat coincidentally) have to get back to my Special Relativity homework.

And also on the assumption that the particle-conservation laws don't apply, which makes it problematic why they apply to single particles either. All neutrons ought to vaporize instantaneously, under Hawking's model.

Err, yes, time dilation. Yay mixed up terms!
Would it keep us from leaving the planet? Or would we still be able to do whatever for awhile?
For that matter, what's the range of the time dilation?

Will come out of what, the LHC, or the pajama party? I'd imagine it's the former, only because Physics departments tend to be sausage fests.
I think it would be ironic if they end up with absolutely no new information, or better yet, if they ended up disproving the astronomically unfeasible "big-bang" theory.
How exactly is the Big Bang theory more unfeasible than intrinsic redshifts or a very precise quantity of hydrogen coming out of nowhere every so often (and eventually forming new galaxies) or any other steady state cosmology idea?
We know that most other galaxies are receding from us and we know that their recession velocity correlates linearly with their distance from us. This suggests that the galaxies were closer together in the past... et c.

*wounded look* I didn't say it was a total sausage fest. One of the two remaining girls in my department (we have a plethora of grad students) works in my lab. In fact I've spent a good portion of the past few weeks deliberating on whether or not I wanted to risk trying to date a colleague, as I found out she is recently single.

...well, I would be among the plethora of grad students... but the plan is to eventually be in an astronomy department as a faculty member *somewhere* and I'm not likely to change my gender in between.
Oh, and as far as dating colleagues goes, it probably doesn't hurt to try although it's probably a good idea if you know them somewhat well and have some idea of whether they're one of those people who goes nuts after a breakup or whether she keeps (or can keep) on friendly terms with exes. If it's the latter (and the latter for you too) then the worst case is it ends and it's awkward for a bit and you move on (unless your department has rules against this, but given the frequency of couples existing in the physics and astro departments I've seen this is probably not a common thing).

This is possible, but I'd like to sort of give people the benefit of the doubt and suppose that they have something that can at least be tested in mind when they say the big bang is garbage.

Granted, and there are quite a few female physics faculty here, as well. But I guess it's mainly the undergrads where we suffer from a lack of teh wimminz.
Yeah, I'm taking it pretty slow right now. She recently broke it off with her boyfriend of a while, and it was because of him cheating on her, so I'm giving a little room partly to not end up as the rebound guy, and partly to figure out what you're talking about with regard to breakups.
We'll see how it goes.
Time dilation would have to be taken into account. Depending on the rate of increase of the black hole, it could take a very, very long time for humans to feel the effects.
Even if it formed a micro-black hole it wouldn't do much. It'd only have the mass of a few particles. At such a low mass it most likely wouldn't overcome the.. force who's name escapes me that causes extremely small scale items to stay separate.

There would be no more time dialation with a micro black hole than the time dialation your hand causes. Time dialation is caused by mass and gravity. Micro black holes have the mass of a few particles.

I would think a complete and total misunderstanding of the theory in and of itself produces such a statement. Basically, in a sense, he may think the "Big Bang Theory" is like throwing a match into a box of dynamite.

Can you explain this, in a dumbed-down form, please? I haven't heard anything about it, but having never taken a formal class on the subject of GR in general and black holes in particular I'm at a loss to understand it from what little I've read on the subject.
Various particles belong to classes which are strictly counted: protons and neutrons are in the baryon class (along with lambdas, and other short-lived oddities), meaning that if the number of protons goes down the number of neutrons goes up, to keep the total number of baryons constant. The electron is in a class with the e-neutrino, so when a neutron changes to a proton, it emits an electron (for conservation of charge) and also an anti-e-neutrino that counts as minus-one on the e-count. (For some thoroughly unexplained reason, the muon, which is exactly like the electron except 200 times heavier, has its separate mu-neutrino keeping a separate mu-count; and recently we've found a tau, which is 10 times heavier than a muon, and has its own tau-neutrino and tau-count; but other particles like the photon have no count, you can make as many new photons as you like, anytime.)
Now if ten neutrons get squashed together into a micro-black-hole, Hawkings says it will evaporate into a bunch of photons and electrons and anti-electrons and whatnot, changing the baryon count from ten to zero. Hawkings doesn't see this as a problem, because there isn't any known reason why ANY of these particle-counts are conserved; but if the count could change from 10 to zero, why could it never change from 1 to zero? My suspicion is that Hawkings is wrong, but to justify that I would have to come up with a new theory of particle physics replacing the Standard Model, and if I had any prospect of doing so, I would be much better paid than I am.

Just a wild stab in the dark... what if the count in one category goes down, but another goes up? Not business as susual, perhaps... but we're not necessarily talking about a business as usual situation.

Nobody really knows why any of the counts are conserved, so until somebody comes up with a comprehensive theory, your guess is as good as mine, and mine is as good as Hawkings'.

Ah, I see. I was aware of the different classes of particles, but was unaware they are so strictly conserved.
I'm curious, other than black holes, are there any other structures that could theoretically violate this conservation?

Equilibrium is hands down one of my favorite action sci-fi movies of all time. Christian Bale's acting is superb, and the fight scenes are very, very well choreographed despite the complexity that the Gun-Kata must have presented in film-making.

The choreography is impressive, and Christian Bale even more so. Not just for his acting, but for his physicality in that role. Watching the movie with the commentary, where it gets to the close-combat fight against 8 or 10 goons, and Bale nails every move, and - apparently - does so take after take... very impressive.
Defnitely one of my faves. Way up there with "Blade Runner" and "Children of Men". I find myself wondering if it would have been any better, even if it had a real budget.

There really wasn't much more they could've done. It was a solid movie with the budget they had, anything more would probably have just made for silly, Matrix-esque fight scenes and special effects.

For those who need a layman's understanding of what's going on, this is a description anyone can understand:
I turn from Barry, whose disregard for intellectual improvement and scientific knowledge is typical of modern Grazia-reading, X-Factor-venerating British society, to his friend Martin, who tries to explain what happened in that trillionth of a second after the big bang by using an empty beer glass - something I secretly hoped someone would do during my research for this article. "Imagine," says Martin, who has an A-level in physics and claims to have read such books as Schrödinger's Cat and the Fabric of the Cosmos and alleges that he's finished A Brief History of Time (as if), "that this glass is a very hot bowl with a frog on its rim." Right. "At the bottom of the glass are some worms that the frog wants to eat." Check. "The frog can't keep still on the glass because it's so hot and so hops around. But as the glass cools, the frog slides down, just like matter did when the universe cooled in that first second." I see, I say (lying). "But imagine if the bottom of the glass had a raised central podium on which the worms sat." Gotcha. "Well, the difference in altitude between the frog at the bottom of the glass and the worms is parallel to the Higgs field of bosons that pertained in that first second and gave all mass-bearing matter its properties." Why does the frog slide down the glass? "Because of time's arrow," says Martin, settling back in his seat proudly. Right. And what do the worms represent? "That's not important." Frankly, I don't think Martin did read all those books. Or if he did, he didn't understand them.
From a fairly amusing, if not unenlightening, article overall.

Scientists at Cern, the European particle physics laboratory in Geneva, have begun their first attempt to send a beam of protons around the Large Hadron Collider, the largest, most complex machine in the world.
The beam of protons has been injected at close to the speed of light, but there are blocks inside the machine that stop it periodically as it works its way around. Each time the beam stops, the engineers can use magnetic fields to make sure the beam is travelling down the centre of the ring. If it's off to one side, it could crash into the ring wall and stop.
We've just seen the first flash of the beam in the machine. And it looks to be well in the centre of the pipe it circulates in. The beam has now made it around the first sector, which is an eighth of the ring
Lots of applause from Cern's control room. The last time they opened a particle collider, in the 1980s, it took 12 hours to get a beam to circulate. This is moving fast so far.
Looks like it will take a while before it's properly going.

Och, BORING. Really wanted the 'minor electrical glitches' to create a giant angry monster somehow. Like the beam hits a microbe that got glued to the side of the accelerator, and transforms it or something. I don't know yer fancy science words for what that would really be called, but you know what I'm talking about, right?

Someone on the live update I'm following has commented that they're landing in Switzerland, they'll probably call it quits and head home, perhaps pick up a Toblerone bar for mom.
Anyway...

It's a big day here at Cern, the European particle physics laboratory, on the outskirts of Geneva. They have begun switching on their Large Hadron Collider, the most powerful particle smasher in the world.
The man at the controls is Lyn Evans. He's a charismatic guy, running the show in jeans, white trainers and a stripey short-sleeved shirt. Yesterday, when I met up with him, he was in shorts and a tee-shirt covered in equations.
The beam is now more than half way around the Large Hadron Collider. Lyn said this morning that it might take two hours to get the beam around if everything went well. So far, all is going fantastically smoothly though.
"We are making very good progress. The beam is now half way round the LHC," said Evans. "At this rate, let's hope that within an hour, we'll get the beam the whole way round the LHC."
There are four giant detectors around the ring, where ultimately two opposing beams will be crashed into one another. So far, the beam has gone past two of these detectors. One of the detectors has already picked up emissions from the beam striking a block that was put in place to halt the beam.

The beam has now reached the last detector, the enormous one called ATLAS. They are one sector away from a complete circuit.
Seriously, this beam is supposed to be traveling at .9 the speed of light, it's gone like 18 miles so far, who's operating this? Virgin Trains?

That's it, they've made it. One lap down. Scientists have just pulled the last block from the 17-mile-long tunnel and seen the beam of protons appear at the last stage of the Large Hadron Collider. So protons have now circulated once around the machine. It has gone extremely well for the scientists here.
They've done it in under an hour. A great first day for a machine that will take us into a new era of physics over the coming decades.
That's the slowest beam you'll see going around the LHC, at around 20mph. When it's up to speed, a proton will make more than 11,000 laps in second.
Okay, it's not going so fast so I guess it will be a while before it smashes, guess I should finish this report then.
:(

They're going slowly to make sure they've got the beam just right and that everything is working properly.
What, did you expect them to just start it up and go into full-scale experiments immediately?

I guess this is why my application to run this thing was turned down.

Nothing but the wasting of billions of Euros and vast amounts of resource to find out information which will be of no practical use.
You mean: "of no practical use save from the fact that among the various technical fall off produced by the LHC project there is the new version of the World Wide Web, for now called GRID"?

However, I can say all the thing with "It can blow the world!" was a great publicity stunt for a branch of science most people normally don't even know about. They might get the money back with a good extra in a few years.

There should be t-shirts, obviously. "I tried to blow up the world and all I got was this lousy Higgs Boson". Assuming they find the Higgs Boson, that is.

Damn...I thought it was a rather expensive way to find a bison.
Yay! Of course, it'll still be a couple months before we actually do any experiments. Still, at least it works!

Aw, man!
It's already kaput!!!
One of the super-cool (-270°C) huge super-conducting magnets that control the particle stream has "overheated" as in "not been cooled down enough" and burned through due to a damaged coupling between two super-magnets.
It'll take months to warm the machinery up, repair it, cool it down again, and restart the experiment.
Bummer!!!
Damned hot magnets. Ruining my science.

Honestly, I figured that something like this would happen eventually. I actually expected it to fritz out on the opening day, what with mixing European and American scientists.

I had hoped it wouldn't happen so soon. Then again, I'm rather glad it happened now and not when it was running at full capacity.
The only reason I'm really upset is that it's a super-conductor and hence the time for cooling/warming phase that takes so long. On a "regular" collider the magnets could be replaced within a couple of days.
And as long as everyone agrees on using metrics and then actually does so, I don't see a problem.
Will the world never end!
