The Large Hadron Collider (LHC) will go online next week, unlocking the universe's great mysteries. Many are fearful it might create a disaster. According to the world's top scientists these fears are not justified.  (Source: EPA)
Despite death threats, fears, and anger among some people worldwide, the LHC's scientists plan to continue with its opening undeterred

The $8B USD Large Hadron Collider will go online next week, becoming the world's most powerful particle accelerator.  It promises answer to some of the universe's most elusive questions.  Among these is the nature of the legendary Higgs boson, a particle long theorized but never observed, which is thought to determine how much things weigh.  The collider, which consists of 7 TeV proton beams harnessed by electromagnets to collide within a 27 km (17 mi) circular tunnel, is expected to unlock many other mysteries such as the differences between matter and antimatter.

However, despite its great promise, many people worldwide have protested the construction of the particle accelerator, believing it could end the world.  Many are fearful that the collider could spawn black holes, which they worry could devour the Earth.  The creators of the LHC, some of the world's foremost scientists, say such concerns are unfounded and convey a lack of understanding about the project.

According to Professor Brian Cox of Manchester University, the public animosity is so severe that American Nobel prize winning physicist Frank Wilczek of the Massachusetts Institute of Technology has received death threats.  Professor Cox, typically sedate, adds irritatingly, "Anyone who thinks the LHC will destroy the world is a t---. "

James Gillies, the LHC head of public relations says he's gotten calls from people literally sobbing and asking him to halt the project.  He states, "They phone me and say: ‘I am seriously worried. Please tell me that my children are safe.’"

While some merely beg Mr. Gillies to convince them that the world is not going to end when the LHC is turned on, he says other take a angrier stance.  He states, "There are a number who say: 'You are evil and dangerous and you are going to destroy the world.'  I find myself getting slightly angry, not because people are getting in touch but the fact they have been driven to do that by what is nonsense. What we are doing is enriching humanity, not putting it at risk."

There have also been numerous legal attempts to thwart construction, none of which have succeeded.  Doomsday predictors argue that there is a small but serious chance the LHC will breed a cataclysm that could kill the world.  Since 1994, when the project was first envisioned, they have fought it.  They frequently quote Our Final Century?: Will the Human Race Survive the Twenty-first Century? - written by Lord Rees, astronomer royal and president of the Royal Society  The only problem is that Lord Rees says his book is not being quoted accurately, stating, "My book has been misquoted in one or two places.  I would refer you to the up-to-date safety study."

Scientists have patiently explained to those concerned many times that the most recent research shows that cosmic rays hitting the Earth daily have more powerful particle collisions than the LHC would.  Thus the added danger of the collider is negligible according to an updated 2003 study from the LHC Safety Assessment Group.  It dispels worries that the reactor might create a deadly black hole.  It concludes, "Nature has already conducted the equivalent of about a hundred thousand LHC experimental programmes on Earth - and the planet still exists."

While the reactor could produce black holes, according to physicists, they would be tiny and would not be capable of growing.  The study states, "Each collision of a pair of protons in the LHC will release an amount of energy comparable to that of two colliding mosquitoes, so any black hole produced would be much smaller than those known to astrophysicists."

Further, the LHC will be incapable of producing possibly dangerous strangelets, based on experimental information gathered at the Brookhaven National Laboratory's Relativistic Heavy-Ion Collider, New York.

However, despite the world's top scientists confident in the system's safety, and the news media constantly seeking to sooth public concerns on the topic, many still remain vocally opposed to the project.

The hadron collider will generate micro black holes, perhaps as many as one a second. But calculations show these will evaporate in an unimaginably short period of time.

In all candor, those calculations *could* be wrong, and the black holes could persist. Even still, the amount of time they would take to "eat up" the Earth would be measured in the tens of millions of years. You have to propose silly extralinear effects to get any sort of real-time risk.

So there is a risk. About as likely as everyone in the US being simultaneously struck by lighting -- all 300,000,000 of us at once. I'm not losing any sleep over either scenario.

From a historical perspective, this isn't the first time we've taken such a chance. Before the "Trinity" H-Bomb test, some people worried the ultra-high temperatures and pressures wouldn't simply stop with the fuel in the bomb itself, but ignite the entire Earth into a mini star.

Quite obviously, they were wrong there as well.

If they employ a Mr. Gordon Freeman at the facility then we've got something to worry about!

So the so-called "resonance cascade" could be, in fact, caused just by two colliding particles in a particle accelerator?

Cool! But if that's so - who's real-life Doctor Breen?

And boy oh boy, do I want to meet Alyx! :p

I don't know, but for some reason I think he'll have Dick Cheney's face.

correction, we have nothing to worry about if gordon's on the job, using his crowbar he'll take down those black holes immediately!

maybe the whole world will end in 60 seconds.

Blah, blah, blah, Mr. Freeman

Just exactly how do black holes 'evaporate ' ? Do they also exhibit this behaviour in outer space, and if so at what rate ? Also what is the ' unimaginably short period of time ' it will take for them to do so--a picosecond,a femtosecond ?

Hawking Radiation. In fact, if the LHC proves this, Stephen Hawking will probably finally get his Nobel.

The speed at which a black hole evaporates is inversely proportional to its mass. Macroscopic black holes trap mass much faster than they lose it from radiation, and thus persist. Quantum-size black holes (the ones from the LHC will be much smaller than even a proton) will evaporate on the order of a femtosecond.

So it's not proven yet-

The same theory which posits the creation of black holes also predicts evaporation due to Hawking Radiation. Thus, if you choose to be worried about black hole formation, you also have to accept the fact that they will evaporate. If you dispute that they will evaporate, no problem, because if that's true then they won't be formed in the first place. Either way, much ado about nothing.

That's not quite correct. Chandrasekhar initially proposed the theory of singularities long before anyone considered the possibility they might radiate. We have experimental evidence for black holes, but none for Hawking radiation. There is certainly the slim possibility that Hawking was wrong, and black holes can exist but not radiate.
