I wrote this response to a blog over at www.americasright.com, a website I quite enjoy. Unfortunately, I’ve seen this skepticism too many times to keep quiet on it, so I’ve included some information that I hope will show why this experiment is not something we should concern ourselves with. Arguing against the LHC shows a couple things, ignorance of science, and a lack of ability to accept science and math as strong evidence. This could be used to severely weaken any argument against global warming on the basis of a lack of science to back it up. If we are unwilling to accept science and math in this case, then why should Democrats be willing to accept science and math with AGW? The result of both cases is the same: detsruction of earth (if the non-science and hype is to be believed). The stakes are the same, the amount of scientific evidence is roughly the same (actually, the LHC is probably even better supported than the case against AGW). We need to take a moment, educate ourselves, and not buy into the buzz around words like black-hole until we understand what a black hole actually is.
Jeff, love the page, and I agree with you on many things.
This, however, is not one of them. The fear from the LHC comes from a combination misunderstanding of physics, and the baggage associated with the term “black hole.”
Black hole basics: Black holes are a collection of mass crunched into a small enough space that “nothing” can escape. This includes matter, and light, hence the black…
Now, there’s a lot of math involved in this, which I won’t get into, but it’s pretty much like this: For any given mass, there is an “event horizon”(schwarzchild radius, technically) which is the size of space that mass needs to be crammed into to become a black hole.
for reference: The Shwarzchild radius for a 1kg black hole is ~1.5 x 10^-27 m, or 12 orders of magnitude smaller than radius of the nucleus of an atom
12 orders of magnitude is such a vast number…it’s literally the difference between 1 dollar and 1 trillion dollars. It’s the difference between having 1 gallon of water, and having the all the water in lake superior 4 times over. It’s almost unimaginably vast.
Now that we’ve covered that, think of a 1 kg object (roughly 2.2 lbs). Stand by that object and see how long it takes the gravity fom that object to pull you into it. See how long it takes the gravity of that object to pull dust into it…It’s a ludicrously small amount of force.
Ok, so that’s a 2.2lb object, how heavy are the particles being collided by the LHC? Well, the LHC is expected to produce a higgs boson particle (and is the primary purpose for the collider) Go look up why it’s important, if you care, to find this particle, that’s not relevent to this discussion of danger. Anyway, a Higgs Boson should weigh about as much as 138 protons, or roughly 69 molecules of hydrogen… It’s hard to imagine how small this is, but I’ll try and compare…
A water molecule is H2O, which contains 10 protons (and 8 neutrons, plus some electron change, but for the sake of ease, we’ll say 69 molecules of Hydrogen gass = 6 molecules of water in weight (it’s probably more like 3, but it doesn’t matter.)) A water drop contains 1.67 10^21 molecules of H20. again, we’re talking magnitude…this is a greater difference than 1 gallon of water and all of the water on the earth (and that’s short by 5 orders of magnitude still….) It’s MORE than the difference between the width of a strand of DNA and the distance from the earth to the sun.
So, you take a mass that is 21 orders of magnitude smaller than 1 drop of water, and determine how much gravity it produces…Then you smash that mass down to a size smaller than anything I’ve mentioned so far, and you’re near the planck length…the smallest unit of measurement. If you know anything of string theory, a plank length is the theoretical distance between strings. It’s so ridiculously small that it’s the distance between two things that exist, it’s as close as two things can be to each other, the space between them is merely representing the fact that two things cannot occupy the same spot. It borders on being 1 dimensional. This black hole would only be slightly bigger than that. IF a black hole existed from this, it would be so monumentally small that it could pass through the empty space in a molecule. It doesn’t matter if it exists for a second, an hour, a year…the likelyhood of it absorbing mass is so small that it cannot sustain, grow, or destroy the earth.
The problem is that people hear about black holes and how they consume everything etc etc etc. It’s simple gravity; at our earth’s core, gravity is enough to crush rock into a molten liquid center, but we’re not afraid of combustion engines. They operate on the same principle, they force liquid gasoline into a small enough space to heat up, vaporize and then ignite.
To get a sustainable black hole that we observe in space, you would need roughly 3 times the mass of our sun. It is impossible, in the truest sense, to create that scale of black hole in our solar system. And for reference, the diameter of a black hole of that size is about 60 km. That 60km black hole doesn’t eat planets, or the galaxy around it.
60 km is only 16 orders of magnitued smaller than our GALAXY. so, the likelihood of an LHC-produced black hole eating planet earth is SMALLER than the likelihood of the black holes that we observe consuming the earth. it’s 5 orders of magnitude smaller…the difference between a centimeter, and a kilometer.
In summary, it is 10,000 times more likely that a black hole being observed by nasa will consume the earth than a black hole produced by the LHC will.
Sorry to prattle on, but this aversion to scientific discovery is comparable to the aversion to fossil fuels on the basis of global warming (a patent hoax in its own right) We conservatives ask scientists to use science to back up global warming, but then we ignore the math and science behind this experiment.
