Take an Amazing Virtual Tour of a 27-kilometer Particle Accelerator

That's quite simply the most beautiful thing I've ever seen!

The comment about the failure situation is incorrect. Any black hole created by the LHC would "evaporate" via hawking radiation before doing any damage. Devouring the earth would require the black hole to have enough initial mass to last the few seconds required to get to more matter.

@live telivision You're no doubt right, but wouldn't it be in keeping with the human experience that just such a fluke "It couldn't happen in a million years" actually did occur, maybe because of some facts we don't as yet understand about the nature of black holes? Isn't it that why we're doing this thing, to find out more about how the universe works? We haven't seen a black hole yet, what do we know about the conditions required to build one?

Not to say I'm against scientific discovery, far from it. And if we did perchance managed to devour the earth, wouldn't that be a hoot :), what would be lost? An insignificant dirt ball with some inhabitants thinking themselves to be the main attraction.

Fire it up, already! I want me some collisions.

If this thing can create a black hole ... then they shouldn't play with it.

"Hawking radiation" is currently a theoretical concept. It would really be a stupid move to contradict Hawking by destroying Earth & the solar system.

If Hawking radiation doesn't exist how the f**k are they going to "evaporate" a black whole ? (even a very small one).

There should be a backup plan. As it is now there is no backup plan, so they shouldn't do it.

I think it would be completed in 2012! the first test run would be done on December 12 , 2012.

anyway , sangoku will save the earth.

This is CMS experiment, not ATLAS, you can see it by the colors: CMS is red and yellow, ATLAS is black and blue. :)

All this conjecture about black hole blah blah does one thing: it underlines humans' inability at proper risk assessment.

The statement should clearly have been: " Personally, I'm glad they’re spending a bit of extra time to get everything perfect, since one theoretical failure situation could lead to major damage to the system costing us *huge* amounts of money, if not scrapping the entire project."

The black hole concept is fallacious in several ways: it's highly unlikely that something manmade is a cosmic 'first post'. If the universe was so unstable as to allow haphazard formations of blackholes that sucked existence out of existence, then cosmic rays would have surely produced such a thing in the 4 billions of years that the earth has existed.

All of this aside, Hawking radiation is not a 'theory' in that someone (Hawking) took a guess at what the universe is like, and we haven't disproved it yet.

It is a theory that is indirectly supported by our entire experience. Yes, we haven't had the change to fondle a black hole at close distances yet, but that doesn't mean that our understanding of day to day events (like transistors and superconductors) is unable to give us a firm theoretical understanding of quantum theory - which has, I must add, so far not been contradicted by *any* observable phenomenon.

And a final PS: if the black hole were to occur, it would be quickly over. You wouldn't have Hollywood style panic. So rein in the fear.

"If Hawking radiation doesn't exist how the f**k are they going to "evaporate" a black whole ? (even a very small one)."

They'd place Paris Hilton and Bill 0'Reilly in it, which would reverse the event horizon, because two black holes of suckage cannot exist next to each other.

That chick is pretty cute...I wouldn't mind using my accelerator on her;)

Id put my accelerator directly into her black hole as well.

Citing bubble-headed claim of the LHC creating earth-devouring black holes is a discredit to the Popular Science name.

It's disappointing that the writer of this glib little blurb couldn't do 30 minutes of web research to understand that LHC will be a pitifully feeble attempt to duplicate the cosmic ray collisions that happen right over our heads constantly.

The *only* thing that is special about the LHC is that there will be enormous data collection machines clustered around the particle collision points to study them. And, there's nothing ominious at all about those masses of wires, silicon chips, circuit boards, and metal as they silently collect data.

Why are we messing with this if we know the possibilties of the destruction that my occur

The Large Hadron Collider [LHC] at CERN might create numerous different particles that heretofore have only been theorized. Numerous peer-reviewed science articles have been published on each of these, and if you google on the term "LHC" and then the particular particle, you will find hundreds of such articles, including:

1) Higgs boson

2) Magnetic Monopole

3) Strangelet

4) Miniature Black Hole [aka nano black hole]

In 1987 I first theorized that colliders might create miniature black holes, and expressed those concerns to a few individuals. However, Hawking's formula showed that such a miniature black hole, with a mass of under 10,000,000 a.m.u., would "evaporate" in about 1 E-23 seconds, and thus would not move from its point of creation to the walls of the vacuum chamber [taking about 1 E-11 seconds travelling at 0.9999c] in time to cannibalize matter and grow larger.

In 1999, I was uncertain whether Hawking radiation would work as he proposed. If not, and if a mini black hole were created, it could potentially be disastrous. I wrote a Letter to the Editor to Scientific American [July, 1999] about that issue, and they had Frank Wilczek, who later received a Nobel Prize for his work on quarks, write a response. In the response, Frank wrote that it was not a credible scenario to believe that minature black holes could be created.

Well, since then, numerous theorists have asserted to the contrary. Google on "LHC Black Hole" for a plethora of articles on how the LHC might create miniature black holes, which those theorists believe will be harmless because of their faith in Hawking's theory of evaporation via quantum tunneling.

The idea that rare ultra-high-energy cosmic rays striking the moon [or other astronomical body] create natural miniature black holes -- and therefore it is safe to do so in the laboratory -- ignores one very fundamental difference.

In nature, if they are created, they are travelling at about 0.9999c relative to the planet that was struck, and would for example zip through the moon in about 0.1 seconds, very neutrino-like because of their ultra-tiny Schwartzschild radius, and high speed. They would likely not interact at all, or if they did, glom on to perhaps a quark or two, barely decreasing their transit momentum.

At the LHC, however, any such novel particle created would be relatively 'at rest', and be captured by Earth's gravitational field, and would repeatedly orbit through Earth, if stable and not prone to decay. If such miniature black holes don't rapidly evaporate and are produced in copious abundance [1/second by some theories], there is a much greater probability that they will interact and grow larger, compared to what occurs in nature.

There are a host of other problems with the "cosmic ray argument" posited by those who believe it is safe to create miniature black holes. This continuous oversight of obvious flaws in reasoning certaily should give one pause to consider what other oversights might be present in the theories they seek to test.

I am not without some experience in science.

In 1975 I discovered the tracks of a novel particle on a balloon-borne cosmic ray detector. "Evidence for Detection of a Moving Magnetic Monopole", Price et al., Physical Review Letters, August 25, 1975, Volume 35, Number 8. A magnetic monopole was first theorized in 1931 by Paul A.M. Dirac, Proceedings of the Royal Society (London), Series A 133, 60 (1931), and again in Physics Review 74, 817 (1948). While some pundits claimed that the tracks represented a doubly-fragmenting normal nucleus, the data was so far removed from that possibility that it would have been only a one-in-one-billion chance, compared to a novel particle of unknown type. The data fit perfectly with a Dirac monopole.

While I would very much love to see whether we can create a magnetic monopole in a collider, ethically I cannot currently support such because of the risks involved.

Im still learning about this subject so if anyone can help me out a bit i would appreciate it. As far as i understand if this black hole was to be created it would fizzle out in an extremely quick period of time due to a lack of required mass, the hawkings radiation theory. Would it not be possible to "feed" it so to speak with enough material to form a lasting black hole with a mass abouve 10,000,000 a.m.u.?
Would containment failure do the job or would you have to "feed" with enough particles first to continue with the matter-antimatter production.
If anyone can answer these questions it would be much appreciated. Thanks.

totally from left feild here but ok, what say they found the Boson particle validated the Hawkings theory, and proved all they set out to...found this, saw that, even made a tame black hole that did just what they said...can someone tell me just how this will trickle down to joe public? I mean will this result in...what? exactly. and i am fully into experimenting but spending squillions just so people in white coats can say there you go! we were right!

Oh my god if its true we will all dye.

If they are aware that there will be a black hole than why
did they build this machine.

It could put an end to the human race.

If a black hole is created it will depend on 'when' it is created how much damage it will do. We are on a spinning planet in an eliptical orbit, in a solar system moving in a spiral galaxy, moving through the universe. Some where between 140 and 330 mi/sec (800,000 and 1,700,000 ft/sec) ft.sec.)
If a property of a black hole is to be stationary in the universe when it is created and If Hawkings evaporation time is correct at 1*10 -23 seconds, the hole will move .000000000000002 inches max before it expires; else it will cut a hole along the resultant stationary vector and exit, hopefully above the tangental plane and not on a collision course with the sun.

My 2 cents,
