BUT....THE FUTURE REFUSED TO CHANGE.

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

When the earth's a SING-GYOO-LARITY...
WE WILL ALL GO ARBITRARILY...

When that E-VENT HORIZON...
Makes the Germans say OH SHIEBEN...

When your looking at a blackhole
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
could be lecturing
a labcoat about the fall...


But don't you worry...



No more 'Geddon, no more Rapture
No End of Days, or Ragner';
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..

Dude, I'm sorry I killed you. =(

I'm not voting for this video.

I'm voting for you.

agreed, this should go in the poe time capsule of best comments ever

SET OFF A BOMB LIKE IN "THE ARRIVAL" or whatever that fucking Jodie Foster movie was

You mean... Charlie Sheen?

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.

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.

Anyway, wouldn't that mean the collider is in the center of the earth?

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.

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.

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.

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

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.

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?

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).

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?'

IT'S OUR ONLY CHANCE!

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.

sweet, i was hoping we would be able to have time to enjoy the mass panic/total lack of inhibition that would insue

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.

5 for fluffy

good read godot

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.

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".

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

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.

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

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.

Relax, they wouldn't be telling us if they hadn't done it already.

What the hell do you know about anything.

Let's challenge his theory over an armwrestle

It's cute when he acts like he's read a book or paper or something.

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

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.
