Large Hadron Collider Sparks 'Doomsday' Lawsuit
smooth wombat writes "In what can only be considered a bizarre court case, a former nuclear safety officer and others are suing the U.S. Department of Energy, Fermilab, the National Science Foundation and CERN to stop the use of the LHC (Large Hadron Collider) until its safety is reassessed. The plaintiffs cite three possible 'doomsday' scenarios which might occur if the LHC becomes operational: the creation of microscopic black holes which would grow and swallow matter, the creation of strangelets which, if they touch other matter, would convert that matter into strangelets or the creation of magnetic monopoles which could start a chain reaction and convert atoms to other forms of matter. CERN will hold a public open house meeting on April 6 with word having been spread to some researchers to be prepared to answer questions on microscopic black holes and strangelets if asked."
So what if it creates microscopic black holes? They'd dissipate in a fraction of a second. http://en.wikipedia.org/wiki/Hawking_radiation
Hold on, haven't we been bombarded by even higher energy particles from space for billions of years now without us, or for that matter the world (as in the rest of all visible matter) turning into a black hole?
The microscopic black hole thing is passably plausible, although any such tiny black holes are far more likely to evaporate almost instantly than launch into a positive feedback state.
The magnetic monopole creation is almost surely complete bunk, as (so far as I know) no one has ever detected signs of such a thing (nor is anyone certain that such a beast can exist). On the other hand, Dirac showed that the existence of even a single magnetic monopole, somewhere in the universe might explain charge quantization. The converse, however, may not hold.
The reason they're doing the experiment is because they don't know what will happen.
Any scientists who say that they know one way or another what will happen are not scientists at all.
Scientific experiments that aren't surrounded by uncertainty and doubt are not much use in removing uncertainty, are they?
-1 Uncomfortable Truth
I think we can all agree that even if it does end the world it would be an even greater crime to build a machine that big and then not turn it on. I would rather be converted into strangelets than living in THAT world.
A nuclear safety officer is hardly on the 'inside of' the LHC team.
The article didn't go into the scientific backgrounds of the guys involved, but the job requirements of being a nuclear safety officer is hardly any prerequisite to being able to in any way accurately understanding the quantum chromodynamics, or even quantized general relativity (which nobody can do yet), etc involved in the LHC.
This would be like an airport luggage screener making claims about the aerodynamical stability of a fighter aircraft, or an electrician who can wire up a new 110 AC outlet in your house making claims about transistor-level details of the latest Intel CPU.
While it's possible they might be experts in highly technical fields hugely beyond their job descriptions, it's fairly unlikely.
This doesn't mean that their concerns are necessarily invalid, but they shouldn't be given any more credibility than other non-members of the LHC team.

As you sow so shall you reap.
After reading the tenth or twentieth scientific article that interviewed people working on the LHC, that includes some wild speculation about remote possibilities that might come to pass when it comes online... this surprises me not at all. I understand being a bit sensationalist to make a more entertaining article. I understand hyping the potential a bit to help keep that government funding coming in. Still, black holes, strangelets, cascading subatomic events, time travelers finding the earliest point to return to... it was a bit much. Maybe you get promoted in experimental physics by making waves and smoking pot with the boss. The you want your name in a magazine so you spin some half-assed idea as though it was a real possibility. The only problem is, some people listened and are now worried.
This is why the Manhattan project was top-secret: two out of six physicists think it might destroy the planet... okay those are good odds, let's try it.
Well then it's a good thing I didn't get my information FROM Wikipedia, but instead just linked to it since it's a convenient resource and the information contained on that article agrees with my previous knowledge of Hawking Radiation.
Sigs are too short to say anything truly profound so read the above post instead.
How could a tiny black hole engender a positive feedback loop? I'm not even speaking of Hawking's radiation here; but how would a few g big blackhole do anything? Its mass being tiny, it's not going to have much gravity at all, so it's not going to attract anything to grow. At most will behave like a heavy particle. Big black holes suck up stuff because their gravity overcomes all other forces, but here that can't be the case.
Clearly, they have mistaken the catchy name for the definition.

“Common sense is not so common.” — Voltaire
If a strangelet chain reaction were possible, then it wouldn't stop at earth, right? So why haven't we detected any strangelet stars? Heck if one of them went nova, we should be seeing strangelet galaxies, no?
Done with slashdot, done with nerds, getting a life.
In all fairness to the LHC people, the worst possible outcome is a blackhole that swallows the earth, not the solar system. It's not like there is magic mass available, to make the black-hole earth have more gravity than the earth does and pull in the rest of the solar system. It would just sit there orbiting the sun like the earth does now.

Due diligence may be quite prudent. However, that doesn't mean these guys are not nutcases.
Far higher-energy interaction happen every day as high-energy cosmic rays hit the atmosphere. If these things could happen, they would have already happened and destroyed the Earth long ago.
Right on! Thank goodness everyone at Slashdot has their PhD in theoretical Physics.
:-(
Damn it, at first I was going to say "ah ha", since I just got my PhD (I defended less than two weeks ago) in Experimental Physics (condensed matter). But then I saw that you qualified it with theoretical physics, and alas, I cannot say "ah ha" anymore
But yet your sarcasm proves my point exactly!
Having a PhD in condensed matter experimental physics, in no way whatsoever am I qualified to qualify the creation of 'strangelets' or microscopic black holes. I've taken my share of grad classes, such as graduate-level quantum mechanics (Sakurai) and E&M (Jackson) with other high-energy theorists, and I've even done a small bit of relativistic quantum field theory (Peskin/Schroeder).
Given all this, I barely even know enough of quantum electrodynamics, much less QCD or anything well beyond that, to make valid judgements of the effects of LHC. But I'm supposed to take the word of a guy on these same topics with far less physics experience than me?
