Concern Over Creating Black Holes

kdawson posted about 8 years ago | from the nothing-to-fear dept.


Maria Williams writes to tell us about worry surrounding the impending startup of CERN's Large Hadron Collider. Some fear that the device, in creating mini black holes, could jeopardize Life As We Know It. While the tiny black holes should evaporate quickly — throwing off so-called Hawking radiation that can be detected — CERN software developer Ran Livneh reminds us that "Any physicist will tell you that there is no way to prove that generated black holes will decay." The LHC site assures us there's nothing to worry about. The flap is reminiscent of the time the Relativistic Heavy Ion Collider went live. The worry then was that "negative strangelets" could gobble up the world.

daveschroeder (516195) | about 8 years ago | (#16082503) crap about John Titor [] actually being a real person.


For those who don't know, in the John Titor story, the CERN LHC allegedly lays the groundwork for using artificial black holes as part of a time machine (made for the military by General Electric, of course!).

(And no, John Titor is not a real time traveler.)

For example:

Along with the prediction of World War III, another notable prediction is that of a Civil war in America, which was predicted to begin in 2004, around the time of the presidential election, and would escalate until 2008, which, according to Titor, "[is] a general date by which time everyone will realize the world they thought they were living in was over."

Even statements like this are subjective and many people still choose to believe; I'm sure there are many slashdot readers (judging from the kind of posts I see here) who believe we are currently in a nascent "civil war" and that, indeed, the "world they thought they were living in was over." This is all typical vague crap that can be viewed a variety of different ways, Nostradamus-style, and never soundly disproven, conspiracy-theory-style. Even now, people are arguing that John Titor's visit may have allowed us to "change our future". Yeah, because the mental giants who believe the John Titor story have had a huge impact on things.


It's quite impressive how many people actually believe this tripe, though.

Actually, the civil war prediction is pretty clear-cut. Do we have two or more large factions of Americans shooting each other for political purposes? No. Therefore, while the country is certainly polarized, we aren't in a civil war.

The line may be fuzzy -- people are still arguing over whether Iraq is in a civil war, but they're shooting at each other (and us). So far, though, the USA is clearly on the negative side of that line.

The American civil war is generally agreed to have begin with the firing on Fort Sumter, not with the polarization of the country or even with the first states to secede from the Union.

A black hole cannot just "suck in" whatever it wants, the matter and energy in question must physically come in contact with the boundary of the body to begin with. Note that no object in the immediate vicinity of a newly formed black hole has its orbit disturbed in any significant way. The gravity of a black hole to anything standing outside its bounds is not particularly fascinating - they do not behave like a drain, contrary to the way they're usually drawn.

The holes being created (IF they even get created) would be so incredibly tiny that they would immediately be attracted to the core of the planet, happily flying right in between molecules and even atoms, only occasionally colliding with them and obtaining their mass.

If, by chance, they are wrong about the decay and one escapes, it could take much longer than you or I need to worry about it until it becomes massive enough (density != mass!) to destroy the planet.

Of course, while we're speculating on silly doomsday scenarios, it could also randomly collide fast enough to grow at an exponential rate and destroy us all nearly instantaneously.

That's not too likely either though.

Re:The world didn't end last time... (5, Funny)

spun (1352) | about 8 years ago | (#16082624)

I think microscopic black holes couldn't eat up the earth due to the three stooges problem. They are so small that only an atom at a time can get in, but the gravity is strong enough to try to suck in more, so all the atoms get bunched up around the event horizon like the three stooges all trying to get through a door at the same time. Problem nullified. Whoop hoop oop! Nyuck nyuck, why I oughta!

dgatwood (11270) | about 8 years ago | (#16082787)

I don't think I buy that reasoning. That's like saying that a {particle beam, laser} won't work because the hole at the end of the tube is only big enough for one {atom, photon}.

Except it's worse than that. As soon as things shift around a little so that a single atom goes in, the event horizon is now slightly larger. Repeat ad infinitum. All it takes is an occasional atom getting through.

A microscopic black hole either dissipates or it doesn't. If it does, great. If it doesn't, we have a problem. It may take millennia to become a serious problem, but....

I think you misunderstand the nature of the disagreement. The problem is not that scientists agree the experiment will have a 0.1% chance of gobbling up the earth ("OK, boys, cross your fingers!"). It's that people that do not understand what the scientists are doing are spreading FUD. "Black holes gobble up stars! Surely we are at risk!"

Of course, no one can say with absolute certainty how things will work, but when you flip on your light switch, it's generally reasonable to assume that it's not going to cause your light bulb to vaporize your city. It's perfectly possible that our knowledge of physics is inadequate to the point where it couldn't have foreseen this, but we understand things well enough to know that this isn't likely to happen, and, indeed, it is happening naturally all the time. You can't hypothesize a risk that you do not understand and go on to tell people that they can't flip on any more lights.

Being cautious about a potentially real issue is one thing, but of course the big issue here is that collisions of similar energy happen, if not commonly, at least not entirely rarely due to cosmic rays. If the world could be destroyed by the side-effects of such a collision, we wouldn't be here to be nervous about it.

You Fear What You Don't Understand (4, Interesting)

eldavojohn (898314) | about 8 years ago | (#16082648)

Precisely, although, if I may add a bit as to why people might still be afraid of this research ...

It's natural to fear what you don't understand. It might even be a quality of a species that determines its success as many things in nature are quite dangerous. For better or for worse, mankind has this built in as a default setting no matter who you are whether you're fearing a black hole or suffering from xenophobia.

I am not a physicist but I think the fears here are quite unfounded. All the math and theory point to a black hole having a finite event horizon. If the black holes they are producing are microscopic and last relatively little amount of time, they shouldn't be very dangerous. I think this has been covered before [] .

It is interesting though, because I believe a black hole's event horizon has a radius proportionate to the amount of mass it consumes. I believe that if you make them small enough, however, they don't last long enough to expand. I would be concerned if they were attempting to make massive singularities to destroy garbage heaps with these but I don't see how those would be possible to create as the only known method is to accumulate so much mass in such a small volume that gravity crushes it into a singularity. My understanding of the collider is that it smashes particles together at a fast rate and, as a result, very tiny and brief black holes may result. As this article [] states:
The physicist Stephen Hawking predicted in the 1970s that black holes would evaporate by radiating away their energy. For astrophysical black holes this is a very slow process, but extremely small black holes should last about as long as a snowflake in hell.

People will, as always, fear what they don't understand so I believe it's hopeless to quell all fears about physics research. I'm sure a lot of people are concerned about this being the next "atomic bomb" technology. Where we "drop" black holes on enemies. Though that doesn't really make sense, it still could have military applications such as creating electromagnetic devices that are so strong they displace gravity and aiming them at your enemies. Sure would make for a cheesy sci-fi book whether it was true or not!

Re:You Fear What You Don't Understand (1, Informative)

Anonymous Coward | about 8 years ago | (#16082827)

It's the mass packed into a certain volume that matters. You can have all of the mass in a galaxy, but if it's spread out over the volume of a typical galaxy, you have no black hole. Once you pack it into a certain density, you reach a point where the local gravity becomes strong enough that light cannot escape. I haven't read TFA, but it seems clear that they aren't trying to pack a bunch of mass to create a "tiny" or "microscopic" black hole. They're colliding exceedingly small amounts of mass into an exceptionally small area. Billions of times smaller than "microscopic".

Unless our understanding of gravity is WAY off here, there's nothing special about this region of space except that we have a bunch of mass compressed into a small area. The black hole has no chance of affecting us because the mass that makes it up is no greater than the mass we put into it. Unless we seriously misunderstand gravity, this thing will disappear instantly because it can't hope to sustain itself.

Primary cosmic rays impact the earth all the time, and these often have far higher energies than even our largest particle accelerators are capable of producing. For any experiment we attempt, we can be reasonably sure that colliding cosmic rays have already produced the same results, sometime within the past few billions years.

There is an approximately equal chance that Pat Buchanan will be nominated as the Democrat candidate for president in 2008. No physicist can prove that this won't happen - just like no physicist can actually prove that Superman doesn't exist.

Unfortunately, it's about the only way a reporter can "sexy up" a story about a particle accelerator. I can't wait to see the headlines in 2007 - "Will the Earth end tomorrow?" (subheading: "Respectable scientists say 'No'").

The beauty of it is, either way the papers won't have to print up a retraction the next day.

"Has anyone seen my car keys? I set them right next to the collider."

  This reminds when I read Brian Greene's Elegant Universe, he mentioned that there was a possibilty of creating another Universe when (if it were possible) smashing together Superstrings. Something like that, I'm not sure where I put the book.

Oh, or Yellowstone goes all explosion on us and brings about a second ice age or something. (There was a Docu-drama on this one.) Oh, or maybe the moon can be partially destroyed and threaten to crash into earth. (Reference to a ABC Family comedy or in some ways to Cowboy Bebop). Oh, or nuclear winter. I am sure I forgot some.

Empirical evidence (1)

frostilicus2 (889524) | about 8 years ago | (#16082773)

Ok, so as long as this remains theoretical we don't know for certain. But, this is unlikely, very unlikely. We should first look at empirical evidence - Collisions with energies of this magnitude happen in space all the time from natural sources (solar radiation etc), and yet cause us no ill effect. So its clear that such an event occurring is very unlikely. Its good that we consider such possibilities, but I'm sure that the probabilities are tiny, one in several billion perhaps. I would consider this to be an acceptable margin to perform an experiment that could destroy the earth, especially one from which we can learn so much.

Odds of finding Higgs Boson (1)

electric_mongoose (988634) | about 8 years ago | (#16082790)

According to this New Scientist article [] you can get odds of 6-1 that the Large Hadron Collider will find the Higgs before 2010 at 6-1. Sounds like a dead cert to me.

There is no stinking Higgs particle (1, Offtopic)

sweetser (148397) | about 8 years ago | (#16082792)

The reason several billion dollars are going into the electromagnetic crop circle known as the Large Hadron Collider is to detect the Higgs particle. The standard model of physics predicts all the detected particles we have seen out there. The model can be represented by the symmetry groups U(1) for EM, SU(2) for the weak force, and SU(3) for the strong force. Well, it can do that so long as none of the none forces has a mass. Oops, that's not what the experimentalist tell us.

So what do theoretical physicists do? They try to sneak in something without breaking it. That is what is known as Higgs mechanism, or the false vacuum Mexican hat dance. Instead of saying the vacuum is a vacuum is the home field of zero, it is claimed that vacuum is utterly false, there is a Higgs field everywhere there can be a where, so that fundamental particles can get some mass when they need it (always). This mathematical trick works because it doesn't mess up the symmetry in the Lagrangian (a fancy way of writing all the interactions that can happen in a volume), but does get the vacuum to add the mass back in.

You may have noticed gravity is not in the standard model. Guess what is going to happen when gravity gets in? Gravity will break the nice symmetry, and no Higgs boson will be needed.

The uber-sophisticated will complain (whine) that gravity is done by a spin 2 particle, but the Higgs is all about inertia, so it must be spin 0. This is not a flaw, it is a sign from Einstein, specifically the equivalence principle that gravitational mass (the spin 2 thing) must be cow-tied to inertial pass (the spin 0 thing). There is no way to wrestle a steer to the ground unless those two are expressions of one and the same thing.

The way I do it, because of course I have my own personal unified field theory, is to use a second rank symmetric field strength tensor for gravity and the spin 2 stuff, and then use the trace of that very same tensor for the spin 0 Higgslike stuff.

What happens when multiple black holes combine? (1)

popo (107611) | about 8 years ago | (#16082794)

If "multiple" tiny black holes are being created, and they combine, don't we
get a "less tiny" black hole?

And isn't that... "bad"?

It's not like we'll ever _know_! (0)

MikTheUser (761482) | about 8 years ago | (#16082795)

If a black hole is created and remains stable anywhere on earth, you won't even have time to scream "Oh, shit!" before your molecular structure is torn apart.

So, no sense in worrying about an event that you will not notice is happening and will never be able to remember.

  • the 'vortex' secondary fire of the missile launcher in the old SNK arcade game SAR: Search and Rescue
