This is just a clip from Sephiroth's final attack, about 5 hours in after most people have stopped watching.

It's sad to think of that asshole
Who thought that science was
going to kill us ALL...

And you may have thought it insane
That this ev-er-ey day layman

But don't you worry...



No more 'Geddon, no more Rapture

Thank science for this amazing feat...

Cuz if the knowledge dropped on you
Doesn't scare your offspring too...

THEN YOU KNOW YOUR ASS IS FUCKING OB-SOLETE!

AND, WE, WILL..

And yet, you know in the 38 seconds it would take us to die someone would update the Large Hadron Collider page on wikipedia to reflect the fact that it killed us all.

The Fog (the newer Stephen King version) is a half-way decent movie about a interdimensional CERNish project gone awry. Recommended viewing for a rainy day.

Rovin
The Mist, not The Fog.

yeah thats it. the dog was a crappy movie.

how many movies are we talking about here?

"The Dog" doesn't sound interesting at all.

I read your description as "creates a non-momentary black lol" as if you couldn't get through the statement without laughing your ass off.

Looks like a Scientology ad.
Cleaner82
I hope that I would at least have time to say, "Bummer."
Cleaner82
Anyway, wouldn't that mean the collider is in the center of the earth?

TeenerTot
As a communications major, I hypothesize that the earth's gravitational center would immediately move to coincide with the position of the black hole. Which would give us all such a case of whiplash we wouldn't even notice the whole collapse into a singularity part.

Cleaner82
We'd all fly off the earth like we were on the hood of a car that just put on the brakes.

That is my official science ruling.

afp3683
This reminds me of some Final Fantasy boss' final attack.
phalsebob
Yea... ok. Seriously, do any physics people here have a more realistic notion of what would happen if they made a black hole. I assumed that the hole would orbit around inside the earth for hours, if not days before it gained much mass, and then the earth would begin to shrink and heat up. The mole people would also be very pissed.
Syd Midnight
CERN can't make a black hole big enough to have a noticeable gravitational field. Every day cosmic rays hit the atmosphere with way more energy than CERN could ever dream of. So it's no different than normal background radiation, except they can do it on demand.

mouser
Thank you Syd. Was about to point out the same thing.

Screwtape
Actually, it would pretty much be the same thing, except that two giant hands would manifest themselves, one on each side of the hole to help open it faster.

This is how the world ends. Not with fire or ice, but with goatse.

phalsebob
Well... I didn't think CERN would be able to produce a dangerous black hole. I was wondering what would happen if one, magically, did form. But since you are answering - what kind of energy would you need to create a tiny hole with, say, the mass of a few thousand protons? Would it be a 'white hole'? How big a hole would need to be created before it is dangerous? May I have some chocolate please?

Syd Midnight
Some guy who works at the LHC has a megathread on the SA forums, he said that a black hole would have to have a very substantial amount of mass to survive long enough for its gravity to pull in matter. The smaller they are the faster they evaporate, so they'd only live for femtoseconds. Also the smallest ones have such feeble gravity that they pass through matter like a neutrino (as I understand it).

HarveyTibbar
From my brother with a Physics degree, asked on the eve of the CERN test...

"They aren't exactly making a Black Hole. They're recreating the conditions of a black hole. However, it will be like a mouse farting, the smallest amount of matter swallowed before it is 'neutralized.' At least that's what they think."

'So they don't know exactly how much matter will be swallowed up before it peters out?'

"Right. They're pretty sure it's very small though, unnoticable."

'But they don't know?'

"Correct."

'Well, if we took the time to figure out what would happen before we did anything, we wouldn't get anything done would we?'

TO THE SHUTTLES!
Doctor Arcane
IT'S OUR ONLY CHANCE!

Paranatural
To answer phalsebob: It doesn't really matter because a black hole with a mass of a few thousand protons wold be exactly the kind that would disappear basically instantaneously. You'd need an initial mass the equivalent of Everest to get yourself started with a black hole that should be big enough to matter. To convert that much mass into a black hole would take several thousand times the amount of energy of every power station on the planet operating for years.

Unfunny follows. Sci-fi author Greg Bear used a singularity weapon as a Berserker earth killer in one of his books, ran it past some physicists, and described it something like this:

If a singularity lasted long enough such that its matter gobling exceeded its matter loss from Hawking radiation, and it was created with less than escape velocity, it would in fact just spiral down within the surface of the earth. It doesn't experience friction from the surrounding matter, as anything that might rub simply falls into it. The singularity continues sucking in matter in initially microscopic but exponentially growing amounts, its initial velocity diluted to the average of the momentum of the matter it encountered. It would arrive near the center and stay there, consuming both matter and volume, while continuing to grow in size. Gravity at the surface wouldn't change much for a while, but p seismic waves originating in the core would be detected by seismometers with increasing frequency. Eventually the continental plates would compress against each other as the underlying volume decreased, and massive surface earthquakes would ensue. Most people would die off at this stage. In a climax, the plates just start jutting madly across each other as the mass of the earth is lost inside the black hole's Swartzchild radius. In Bear's book, the whole affair takes a couple of months, with seismologists aware of what's transpiring 3 or 4 weeks in.

That, to me, is a lot more plausible that the earth's surface suddenly getting drawn into and ever expanding cone. Myself, I'm not too worried, as higher energy collisions occur regularly from cosmic rays hitting the upper atmosphere, and the Earth's still around.
Takselvaki
sweet, i was hoping we would be able to have time to enjoy the mass panic/total lack of inhibition that would insue

fluffy
Actually, would the gravity ever change at all (until something falls into the singularity, I mean)? I mean it's not like the total mass would ever change, it'd just shift inwards.

Actually I'd expect death to come much more quickly, because when the center of the planet goes away, other mass will have to get sucked in, and most likely the atmosphere would go underground long before everything else does.

good read godot

Albuquerque Halsey
Glad to know all that waiting paid off.

Recalling some skooling from some time ago:

Maximum LHC energies are 1.15e6 GeV which with complete conversion to mass is 2.05e-21 kg. That mass would exert 1 G out to 1.18e-16 m, roughly one tenth the size of a small atomic nucleus, and 1 G is miniscule compared to other forces at that scale. If the cloud of sub atomic particles our singularity passes through were behaving like points (rather than waves), it would require a dead on hit to pick up mass. Something like solar neutrinos, which just don't interact, and pass through the earth barely seen.

Chalkdust
I like the idea that, if a persistent mini-black hole was created, they'd go to great links to make sure nothing came in contact to add to its mass.

Such as a little roped-off area where light bends in a weird way, and signs reading "Do Not Touch the Singularity".

Chalkdust
Haha, great LENGTHS. What the fuck is wrong with me.

baleen

It would be funny if the first thing that was sucked into the core was everyone's pants and bras. Time would dilate in such a manner as to appear sped up, thus rendering the world's last moment a cruel Benny Hill sketch.

Desidiosus
Dammit baleen, you're making me look forward to it

Repomancer
The octopole factor had to exceed the dipole by several orders of magnitude and it had to have a soliton-like solution, IIRC, but the math worked when starting from those assumptions.

The video was ridiculous. A black hole doesn't have any more mass (and therefore no more gravity) than what made it; if the Sun turned into a black hole tomorrow (it can't, not enough mass, but for the purposes of argument) the Earth's orbit would be unperturbed.

wtf japan
Yeah, this is the sort of thing I wish was all TOP SECRET. Like the Manhattan Project. That way I don't have to worry about it.
Jeff Fries
Relax, they wouldn't be telling us if they hadn't done it already.

DopeFiend
Thanks for the nightmares.
KnowFuture
HAHAHA according to this video the Americas will be taken out last IN YOUR MOTHERFUCKING FACE EASTERN HEMISPHERE

Ryo-Cokey
I have to stop by to point out that black holes have infinite density, not infinite mass. Gravitational pull is a distance squared equation, meaning the tiny black hole wouldn't be able to suck up much of anything.

Mass has the exact same gravitational pull whether it in sitting around in the form of an apple or in a micro black hole.

Anyway, it all depends if Hawking's radiation theory is correct. The theory is currently untested because micro black holes to not appear to occur in nature.

What the hell do you know about anything.

That music had me quite relaxed about the apparent inevitable doom of us all.

Yeah, it's nice to know that at least we'll have nice soothing music as we get sucked into oblivion.

In his 1990 novel, Earth, David Brin addressed this subject. The rest of the concepts he introduced in the book were highly speculative, but he proposed a pretty straightforward means of dealing with the black holes. The black holes would not experience any friction, so they would probably maintain the orbit they had when they were released, near the surface of the Earth. The center of gravity for the earth/moon system moves with their orbit around each other, which means that sometimes the black holes would be far above the earth and other times below. The protagonists ultimately plotted the orbits of the black holes and blasted them with anti-matter when the orbit brought them into the open air.
Camonk
Yeah, but in his 1990 book, David Brin also sucked up a bunch of butts right into his inept mouth cause that's easier than trying to write a good book, which he can't do.
