CERN to Morons: Large Hadron Collider Won't Destroy Earth. Morons.
Posted by Gizmodo US Edition at 2:28 AM on April 1, 2008
Contrary to the somewhat feverish claims laid out in an recent lawsuit, when our favourite particle-smashing, Force-finding Large Hadron Collider is switched on soon it will not result in the destruction of life as we know it. Such claims are "complete nonsense" say the scientists at CERN (and everywhere else,) in response to the suit. They should know: it's their machine, they designed it and they've been telling everyone for a while that their research shows it's safe.
The lawsuit filed by a group of Hawaii residents is alleging that not enough safety checks have been made by CERN to prevent disaster when the LHC goes live in the coming weeks. It may "create unsafe conditions of physics" which may have disastrous effects. How? Well, you may imagine a micro black hole gobbling up everything unstoppably, while a strangelet (a hypothetical clump of particles including strange quarks) may run amok converting all nearby matter into strange matter, also wrecking the Earth.
James Gillies, a CERN spokesman, suggests this is rubbish in this response to the New Scientist: "The LHC will start up this year, and it will produce all sorts of exciting new physics and knowledge about the universe." It's no threat at all, he says: "A year from now, the world will still be here." The LHC is actually designed to probe the boundaries of physics, and while a 2003 safety study did conceed that micro black holes or magnetic monopoles may be formed, they would be short-lived and offer no threat.
CERN physicists will be talking about safety in an open house discussion on April 6. [New Scientist]

@ManjiKengo: To go along with this notion I think it would be a good idea to have the Dr. Otto Octavius on hand to handle this situation if it fact this thing generates a tiny black hole but then starts gobbling everything around it. I think it should be set atop of a rickety abadoned harbor station just in case.

I guess no one else sees the irony of the CERN fellow saying everything is safe, yet the whole reason for the LHC is to try to recreate events we have not been able to witness and do not fully understand.
I am not saying I am against the LHC going live, but if this guy had reason to be so confident, the LHC would not need to be around. However, reward always comes at a risk. Do not forget the Drake Equation had a variable for "societies that destroyed themselves"'. We could all become a statistic!

If you look at the specs of the LHC, the ACTUAL amount of energy used in EV (electron volts) is very small. IF a micro black hole or monopole is generated, there is no way the energy imparted to the creation is large enough to make something substantial.
When they say "micro black hole"...they mean MICRO...as in: so small you can't measure it with the human eye. The tiny creation will just vaporize within micro seconds (or even faster, maybe pico or femto seconds).

Hawking radiation makes the tiny black holes disappear pretty much instantaneously.
Besides, if you compress a grapefruit enough for its mass to create a black hole; 3" away from it, it still has the gravitational influence of a grapefruit. So, no worries.

I came in here to say this. You'd basically have a tiny point with the gravitational pull of a grapefruit. Which probably wouldn't affect much since it would pale in comparison to the gravitational power of the earth.
IE, you don't feel the gravitational pull of grapefruits now, so a black hole formed from a collapsing grapefruit wouldn't be noticed either.
Plus "Black hole grapefruit" doesn't quite have the same ring to it.

When they first tested the atomic bomb (not 100% about the validity of this) But they thought that the way the atomic bomb would work would be through a chain reactions through the atmosphere. That's why it gets so large. But they didn't know whether it would be just big or if it react through the entire earth's atmosphere and basically destroy the earth.

@gibson042: you have to pick a frame of reference to measure movement. if you're in a car and see the car next to you keeping pace, it hasn't moved relative to your car. stand on the side of the road and view the same car and it obviously has moved. the vague "universe" frame of reference that ripfire4 is referring to would be like standing on the side of the road. if you magically found the "unmoving" center of the universe and used it as your frame of reference, the earth (and the sun, and all the other planets) would have moved away from you in a year's time, even if the earth is in the same position it was 365.26 days ago when using the sun as a reference.
if you want a real mind blow, do some research on how frame of reference affects observations when things are moving really really really fast. (think speed of light fast). things that seem to be constant (like the "steady" passage of time, for example) don't seem to be constant anymore. example: in a way, we've already time-travelled. the russian cosmonaut that (still?) holds the record for the most time in space is 1/60th of a second in the future (kinda). because he was moving quite fast, relative to the surface of the earth, he experience time differently and is basically 1/60th of a second younger than he would have been if he'd stayed on the ground. this is why physics rocks and the LHC needs to fire up on schedule. Higgs Boson FTW. (i mean come one, they don't call it the "god particle" for nothing)

@lordargent:
So if you take a grapefruit and smash it down to a point; you've created a black hole with the mass of a grapefruit (which doesn't have much affect at all on anything within a few inches gravitationally speaking). Got it. A black hole without much mass is mostly harmless.
But since this mini-black hole is still very, very dense, won't it drop through all the matter below it due to the pull of Earth's gravity, and fall right through to the center of the earth? Maybe it would bounce around a bit before settling, but the center of the Earth seems like a nice place for it to end up.
How big is the event horizon of a black hole with the mass of a grapefruit? Because if it is bigger than the atoms that make of the stuff at the core of the Earth, it'd consume them, and add that mass it its own. The added mass would expand the size of its event horizon, allowing it to chow down on more of the stuff at the core of the Earth. Eventually, all the Earth could be sucked into the black hole. Wheee!
I guess the question is; how massive must a black hole at the center of the Earth be, to be large enough to consume the Earth?
I'm a bit fuzzy on the math, but I think it has to be a lot bigger than a grapefruit. Don't tiny black holes actually radiate mass away from their event horizons and shrink, eventually winking out of existence in one last blast of radiation?
Damn, I need to go back to school.

Posted 7:04 AM 2/4/08
@FLskydiver: Wait a minute.
From Wiki: "All black holes are believed by many theorists to emit Hawking radiation at a rate inversely proportional to their mass. Since this emission further decreases their mass, black holes with very small mass would experience runaway evaporation, creating a massive burst of radiation at the final phase, equivalent to a nuclear weapon exploding."
Sorry, Hawaiianites.

@FLskydiver: Whoops. The surface at the Schwarzschild radius acts as an event horizon in a non-rotating body. So the size of the event horizon of a black hole formed from a grapefruit (the distance from the singularity at which matter or energy falling inside will be consumed by the black hole) has to be somewhat proportional to the ratio between of the size of the Earth (which of course is all-in-all denser than a grapefruit) to 18mm. In other words, small enough to be of no consequence. I think.
Go ahead CERN guys, let it rip!
FLskydiver
FLskydiver
Posted 6:45 AM 2/4/08
@FLskydiver:
Ok, did some math (not really). The Schwarzschild radius of the Earth is about 9mm. That means, if you wanted to compress the all the matter in and on the Earth to a point where it would inevitably form a black hole, you'd need to squeeze it down to a sphere with a diameter of about 18mm.
So a grapefruit would need to be squeezed quite a bit smaller than that, I guess. Still trying to figure out the size of the event horizon.

We can't be absolutely certain that the LHC poses no risk of creating a black hole. To suggest otherwise would not only be naive but irresponsible. This experiment is the first of its kind; it is new and untested. Therefore, we can't say that the doomsayers are 'morons', because those same minds warned about the splitting of the atom. On the positive side, nothing may happen - but we cannot say that it never will, or can't. Because it can.

There is always a risk, even if it is small. This is a revolutionary and new, untried project. True, it is CERN's machine, and yes they did build it, but it would be both assumptous and naive for them to just dismiss the possibility of risk. That would be tantamount to saying that the splitting of the atom was something that posed zero risk, when Oppenheimer & co knew quite well what the dangers were. So do CERN when it comes to the LHC. Don't be dismissive of real possibilities. After all, it's humanity's most embarrassing flaw.

CERN's web site states that we have not been destroyed by effects of cosmic rays and micro black holes will evaporate.
However, cosmic rays travel too fast to be captured by Earths gravity, and Hawking Radiation is disputed ([arxiv.org]) and contradicts Einstein's highly successful relativity theory. Collider particles smash head on like a car collision and can be captured by Earth's gravity, and relativity predicts micro black holes will not decay (Hawking called Einstein doubly wrong, yet it is Einstein who is repeatedly found to have been correct in his theories). There is currently no reasonable proof of LHC safety, LSAG (LHC Safety Assessment Group) has been trying for months to prove safety without success. I hold the minority opinion that it may not be possible because it may in fact not be safe.
Cosmic Rays from the legal complaint.
…any such novel particle created in nature by cosmic ray impacts would be left with a velocity at nearly the speed of light, relative to earth. At such speeds, …, is believed by most theorists to simply pass harmlessly through our planet with nary an impact, safely exiting on the other side. … Conversely, any such novel particle that might be created at the LHC would be at slow speed relative to earth, a goodly percentage would then be captured by earth's gravity, and could possibly grow larger [accrete matter] with disastrous consequences of the earth turning into a large black hole.
If this thing is so safe, why aren't CERN scientists allowed to express any personal fears they might have about this Collider?
Alleged in the legal action: Chief Scientific Officer, Mr. Engelen passed an internal memorandum to workers at CERN, asking them, regardless of personal opinion, to affirm in all interviews that there were no risks involved in the experiments, changing the previous assertion of 'minimal risk'.
(Statisticians generally consider minimal risk as 1-10%).

OK OK OK how bout this...
1) Scientists aren't always right
2) Scientists sometimes lessen the risk of a project or experiment to obtain proper funding (NO, ABSOLUTELY NO FLIPPER BABIES.....well....ok, maybe ONE flipper baby)
3) Humans have always been plagued with that little thing called hubris...it generally leads us into messes that could have been avoided
And yes, before anyone states the obvious that the next reference is science fiction and not fact...I am acknowledging that the following reference is science fiction and not fact...however...
Did anyone read that old short story by Larry Niven about the team of scientists that find this alien machine and they can't figure out how it works so they start messing with it and turn it off and it turns out it was getting its power from a micro black hole that was held in place by a whopping humongous onlyanaliencouldmakeit gravitational field and when they turned it off the micro black hole was sucked up by the planet's gravitational field and before killing the scientist it passed through it fell to the center of the planet where it started bouncing around in the core and eating up all of the core's yummy goodness basically dooming the planet?????
Anyone...anyone....

Hmm perhaps you all remember a little movie called superman? Jurel told everyone that Krypton would blow up within 30 days. No one believed him and look where that got them.

The Scientist also claim the LHC does NOT play Doom, and that Earth will be around long enough for Skynet to go online

There is strong evidence that the LHC *will* destroy the world. It's called the Fermi Paradox: where are all the extraterrestrial civilizations? One logical explanataion is that they destroy themselves with ill advised experimentation.
Civilizations that reach this level of technological capability without real understanding of the underlying physics involved inevitably destroy themselves.
Those cosmic ray events are just the signature epitaph of yet another baby civilization poking its fingers into the electrical socket of spacetime and getting severely fried.
Lets understand a bit more of the physics involved. The physics community can't even make up its mind whether a recent paper by some surfer guy is a major breakthrough or nonsense. Claiming that the LHC is zero risk is hubris to the extreme. Even if the probability is once chance in a quintillion, the expected loss is infinite.
And they said the space shuttle had a one in a million chance of failure.

Silly! It's not going to blow up the world, it's going to create a time dilation portal which will then proceed to resurrect Jesus and once he's back you better be scared. He's bringing his thwomping stick and you're all invited to the party.

Now that I think about it, the Hadron is the big bang as we know it, its the very answer to the 'infinite time' question. It closes the time loop.
Predestination Paradox ftw.

What is Gizmodo basing their ridicule on? It is amazing how many commenters also pitch in with a har har. There is a SMALL change of the production of detructive particles/mini-black holes, and the LHC people recognize this. A large part of the issue is to do with probabilities. If the consequence is, say, the destruction of life on Earth, then the probability of that event ought to be darned small. There is an academic paper on the probability isse by Adrian Kent. ([arxiv.org]). It's not all silly talk. Actually Kent is a very conservative scientist in many respects. Get a clue Gizmodo - look up some facts and you know THINK. You techie types should be able to handle that.

Dilbert Oops
Have you see the Dilbert Oops article?
And who exactly ran the numbers to decide it wasn't that risky? After all, the whole point of the Large Hadron Collider is to create conditions that are not predictable. If someone already predicted what would happen using nothing but his laptop and Excel, and determined it was safe, I don't think we're getting our $8 billion worth.
I can't see the management of this project spending $8 billion, realizing it was a huge boner, and then holding a press conference suggesting it be turned into a parking garage. I'll bet a lot of people in that position would take at least a 5% risk of incinerating the galaxy versus incinerating their own careers. I know I would.
