Large Hadron Collider Goes Live September 10th
Naznarreb writes "CERN announced today that the first attempt to circulate a beam through the Large Hadron Collider will be on September 10th, 2008. You can read the press release here. They also announced the event will be webcast live. According to the release, they're just planning to run a few tests laps, not smash any particles, so the world won't be ending quite yet." And despite that September 10th date, according to the BBC, "On 9 August, protons will be piped through LHC magnets for the first time."
And will take 1 day to warm up right?
It is a good day to die !!!!!

The other LHC
Unless, of course, we're finally in the timeline where the LHC never quite works.
OR the timeline where you're the only non-cloned human left alive, surrounded by clones of your ex-girlfriend. Then you'll wish you didn't get on her bad side right before 'the accident'.
Nothing travels faster than the speed of light with the possible exception of bad news, which obeys its own special laws. So I think we'd hear about it first.

FARNSWORTH: So what are you doing to protect my constitutional right to bear doomsday devices?
N.R.A. MAN: Well, first off, we're gonna get rid of that three-day waiting period for mad scientists.
FARNSWORTH: Damn straight! Today, the mad scientist can't get a doomsday device, tomorrow it's the mad grad student. Where will it end?
There is virtually zero chance the LHC will produce micro-black holes.
Even if it somehow does, they will very likely dissipate in fractions of a second.
Even if they doe form, and are stable, they will be so small so as to sink to the center of the earth and star devouring it at the alarming pace of 1 atom a year.
For frame of reference you have about 7,000,000,000,000,000,000,000,000,000 atoms in your body.
So it would take billions of lifetimes (or more) for you to even notice the effects if one were stuck in you.
Easier to ask forgiveness that permission. Especially easy if there's no one left to ask forgiveness of.
Your courageous and selfless spelling corrections have made me a better person.
Sorry to self-reply, but even once it got going, it wouldn't destroy us immediately. A black hole with the mass of the Earth still only has Schwarzschild radius of 1.5cm.

Looks like 9 September will be a good day to charge up my HEV suit and sharpen my crowbar...

What has *science* done?!? -- Dr. Weird (ATHF)
it would be destroyed almost immediately due to Hawking radiation.
Awesome. I always knew Stephen Hawking was a badass, but now I find out he's a superhero with the power to destroy black holes!
I can see it now: thousands of people panic through the streets, while Stephen Hawking slowly wheels himself into a phone booth, only to fly out a second later and fly to the black hole, destroying it instantly with his Hawking radiation eye-beams! That's going to be sooo cool!
I must admit, his disguise is ingenious. I never suspected he was anything other than a mild-mannered physicist.
Oh, thank heavens... So beach front property in Geneva is still a good investment then...?
Sig Battery depleted. Reverting to safe mode.
A red crowbar has been sent to CERN in anticipation of the LHC particle accelerator going online.

Sucked into a microscopic black hole
You will need: a microscopic black hole. Note that black holes are not eternal, they evaporate due to Hawking radiation. For your average black hole this takes an unimaginable amount of time, but for really small ones it could happen almost instantaneously, as evaporation time is dependent on mass. Therefore you microscopic black hole must have greater than a certain threshold mass, roughly equal to the mass of Mount Everest. Creating a microscopic black hole is tricky, since one needs a reasonable amount of neutronium, but may possibly be achievable by jamming large numbers of atomic nuclei together until they stick. This is left as an exercise to the reader. [I love that part].
Method: simply place your black hole on the surface of the Earth and wait. Black holes are of such high density that they pass through ordinary matter like a stone through the air. [Yeah, so then how will I place it *on* the Earth. Lousy instructions.] The black hole will plummet through the ground, eating its way to the center of the Earth and all the way through to the other side: then, it'll oscillate back, over and over like a matter-absorbing pendulum. Eventually it will come to rest at the core, having absorbed enough matter to slow it down. Then you just need to wait, while it sits and consumes matter until the whole Earth is gone.
Highly, highly unlikely. But not impossible.
Earth's final resting place: a singularity of almost zero size, which will then proceed to happily orbit the Sun as normal.
Source: "The Dark Side Of The Sun," by Terry Pratchett. It is true that the microscopic black hole idea is an age-old science fiction mainstay which predates Pratchett by a long time, he was my original source for the idea, so that's what I'm putting.
If nothing comes from this demonstration but a black hole it will definitely suck.

No way, I'm not getting sucked into that again.
Your statement is true even if they never turn on the LHC.
Yeah. He looks totally different without his glasses. You can't even recognize him.
Yes, I'll probably get modded troll or something for this, but it needs saying.
There's many comments in here about "oh, what about Sept. 11... couldn't they pick a better day?" and the like.
NEWS FLASH: The rest of the world does NOT come to a screeching halt every Sept. 11th. All points of business are NOT put on hold on that one day of the year. The rest of the world has moved on, if they even stopped to begin with. GET OVER IT!
LHC isn't even located in the USA for christ sakes.
Yes, the Sept. 11 events were sad, but seriously... stop criticizing all events taking place somewhere on earth on or around that date.

I can see it now: thousands of people panic through the streets, while Stephen Hawking slowly wheels himself into a phone booth, only to fly out a second later and fly to the black hole, destroying it instantly with his Hawking radiation eye-beams! That's going to be sooo cool!
The image is funnier to me if he never gets out of his wheelchair. He slowly wheels up, has his machine say "Take this, you bastard", and then the Hawking Radiation spews forth!

Kingons and Queons are believed to travel faster than the speed of light, but I hear it's quite difficult to harness their power.

Maybe we've finally figured out why we haven't had any luck with SETI yet? Perhaps any civilization advanced enough to begin broadcasting in the radio spectrum will, within 100 years, start running scientific experiments that are sufficiently dangerous to cause the extinction of the species? Is that possible?
On second thought... that's a silly theory, never mind! I'm going to go back to my very important medical experiments. It's pretty cool stuff, actually. I'm using virus-borne DNA to reanimate dead cells to help critically ill people. I think I'm on the verge of a breakthrough but they're going to cut off my funding if I don't get any results soon! Maybe I'll have to take a few shortcuts... use highly unstable, mutation-prone RNA instead of DNA... maybe skip straight to the human testing phase using this cadaver I have lying around my lab...
Anyhow, have a good day everybody!
Could you imagine what it would be like to be on the ISS when the earth is destroyed by a LHC mbh.
The earth would fold up, only a 1% consumption would be needed to make it impossible to land on the earth and survive, but if the earth all went in a few hours or less. wow. And with the angular momemtum of the earth, the mbh would have to rotate on the earth's axis and the mbh would send its radiation beams away from the iss so the iss could be survivable from that prospective. Also, the aero drag would be gone and so orbital reboost would not be needed. I wonder how long they could survive? Also, since the mass of the earth/mbh doesn't change, all those nasty time-drag effects won't happen at the orbital distance of the iss.
It would make a nice sci-fi short story noir if a multi-year survival could be speculated.
Regards.
That makes me feel much better. Although, how did a micro-blackhole on Earth end up with the mass of Earth...?
<panic mode on>
God invented whiskey so the Irish would not rule the world.
Honest question about Hawking Radiation - how do we know it really exists? As far as I know we've never directly observed a black hole and we've certainly never created one in the lab, so where is the experimental evidence to support it? Shouldn't you say that we THINK Hawking Radiation would destroy said black hole?
Screw the towel. Where's my crowbar?
If the Earth is completely destroyed, you will be the first to know.

You're not.
A black hole with the mass of the Earth has, at one Earth-radius, a gravitational attraction of 1g. (In other words, if you were on the far side of the moon, and the Earth suddenly turned into a black hole, you wouldn't notice.) Closer, it would be much higher. Half an earth radius from the black hole it'd be 4g, a quarter of an earth radius it'd be 8g, etc --- one kilometre away it'd be 4 million g, and one metre away it'd be 3x10^14 g. That's gonna hurt.
So if somehow you were to magically create the 5x10^41 Joules of energy necessary to create a black hole the size of the Earth, on the Earth, I suspect we'd probably know immediately, subject to light speed limits, as the direction of down shifts abruptly followed a few seconds later by the disintegration of the planet and collapse into a accretion disc of white hot plasma. That is, those parts of the Earth that are not blasted outwards by the collapse event, which is what astrophysicists would call 'violent'.
(Of course, *now* I realise that you were actually originally talking about the end result after the consumption of the earth by a tiny black hole, but I've done all the maths now, dammit. So I'm going to post anyway. Besides, once the tiny black hole reaches about .1 earth mass it's still going to be pretty spectacular.)
Yeah. He looks totally different without his glasses. You can't even recognize him.
That doesn't make any sense! He wouldn't be able to see.
