First Collisions At the LHC
An anonymous reader writes "At 1:06 p.m. Central European Summer Time (CEST) today, the first protons collided at 7 TeV in the Large Hadron Collider. These first collisions, recorded by the LHC experiments, mark the start of the LHC's research program."
One of the first events seen in Atlas:

in the history of mankind. this may be the real deal. its possible that we may find the first 'entity' as described as the base of existence in Dewey B Larson's physics approach.

We're still here. :)
im being sucked by a black hole .. does that mean the experiment is a success?
I'm quite suprised that I can reach Slashdot's server now that Earth is destroyed and gone.
this is all sfw. and you've probably seen them already. (but I wouldn't blame you for not trusting an AC seeing as how we are in a pathetically paranoid game theory induced society... anyways, i digress)

You can see the beam status here: http://op-webtools.web.cern.ch/op-webtools/vistar/vistars.php?usr=LHC1 and follow the webcast here http://webcast.cern.ch/lhcfirstphysics/. The webcast screen also has links to each of the experiments.
Well, did they find the Higgs yet?
After all the years of delays and cost overruns, I'm extremely glad to see LHC entering normal operation mode. Congratulations to everybody who contributed and thank you very much for your commitment and hard work! :)
P.S. The labs down the hall that participate in the collaboration will be partying tonight

Apparently the side effects of this experiment is time travel forward several minutes. Oh, and the emitting of large amounts of bogons.

Any particle physicists care to illuminate us on the reason why the LHC might make mini-blackholes but not "strangelets"? Is it because of the kind of particles used in the collisions? Or are strange flavoured particles currently not in favor these days?
Not that it makes much practical difference; if we were to be scrunched into a black hole (I know, I know it's not going to happen) or converted into strange matter we're just as dead. (In fact won't the conversion to strange matter happen at the speed of light whereas it'll take a while for a black hole to grow large enough to shred us?). Kinda sounds like the weapon used in "Ender's game" the "little doctor" (but it left over iron not strange matter).
Watched this happen live and was really stunned with how relatively smooth it went (when you consider the LHC's track record in the past). Yes a couple problems, but the third ramp was the good one. I cannot wait until they start getting enough data to extrapolate any useful data. The potential for new discoveries is almost guaranteed at this point. Higgs boson, or maybe something that completely changes everything we know. Might not get anything though, who knows. They say they will be ramping up to 14TeV in 2012 (7 TeV per beam) with the LHC. So there is still chance for DOOOOOOMMMM!!! (jk ofc :p)
While watching the webcast, just seconds away from the first collisions, the stream went down. I was like w000t! You have no idea how disappointed I was as I realized that it was just my shitty wifi..

And before you ask: yes, you are dead.
And no, you are not in heaven. Your still being on /. should have been clue enough.
It takes a while for the tiny black holes to a) fall to the center of the earth and b) gorge themselves on the earth.
Geeeeez dood- How can you be so stoooopid.
Aaaah!

Nope.

Insert witty comment here
This is certainly a milestone. Now let us hope that prof. Higgs still has the champagne in the 'fridge in case we find the "God particle". Hooray !

http://www.symmetrymagazine.org/breaking/2010/03/30/lhc-research-program-launched-with-7-tev-collisions/ So according to that article, we did the colliding at 7 TeV and their next goal is 14 TeV in 2013, but it's not clear whether that level of 14 is equivilant to the "big bang". Does anyone know what we need to hit in energy levels to reach that?
You're kidding, right? She was already POTUS for eight years. Get with the times, man!
fuck off, seriously
The title could be a little more precise. This is not technically the first collision at the LHC. http://science.slashdot.org/story/09/11/06/0824213/LHC-Shut-Down-Again-mdash-By-Baguette-Dropping-Bird
So does that mean we get to see kdawsons latest dupe before he even (re)writes it ?
...and no blackhole yet !

If you would have been more offensive to religion you would have gotten modded up. The hivemind doesn't much care for references to religion when they are not offensive.
we're to the point that each euro burned is an euro saved from corruption and fraud
This is what makes me laugh about the whole religion thing.
If God [or-substitute-deity-of-your-choice] really is an omnipotent being, how could he let this happen ? He must have known by giving us free will, we were going to use it ?
Even the earliest cavemen probably took apart animals and other cavemen to see how they worked. You'd think he might of had a bit of foresight and brought a rain of frogs or an earth shattering meteor down upon us before we got to the LHC elementary particle level of curiosity.
"I turn my back for one bloody minute, and those damn apes discover the raw particles that make up the universe".
Being omnipotent means you can see everything, even if your back is turned. No excuses, no cop-outs.
Perhaps it's time we drop the whole religion thing as completely unnecessary (apart from an excuse for old people to have a get-together and a game of bingo), and accept that science is all we need now.
Always makes me think of "Understanding Space and Time" by Alastair Reynolds, which can be found in one of his books of short SciFi stories "Zima Blue and Other Stories". Not to spoil the plot but it is one mans struggle with an near eternity of discovering fundamental laws beneath fundamental laws until his "brain" is so big it has to be "scaffolded" to prevent gravitational collapse.
A great read- highly recommended.
would be hoarding (water, etc...). 0, that's most of the problem now? history repeats?
Whoever it was, I hope they're insured.
At 7 TeV it is still running at only half power, the original design is for 14 TeV (two 7 TeV beams colliding). From today on it will run a while, and go down for extended maintenance, at which point they will modify the LHC so it can be cranked up to full spec power.
Still bloody amazing though, AFAIK the tevatron over in the states, now the second most powerfull collider, tops at around 1 TeV
People, what a bunch of bastards
I know some (mostly leftist) physicists who think LHC is a useless toy which is not capable of leading to anything conclusive and is too costly for theoretical curiosities.
What if God [or-substitute-deity-of-your-choice] wants us to discover those particules so we can be buddies whit Her ?
She could have made us so from the beginning, but you know, sometimes, the journey is more important than the destination.
I just blacked out! I had a dream/vision where I saw myself eating a meatloaf sandwitch and chips..oh..sorry..that's a TV show. Or is it?
My cellphone's gone missing...
Stupid blackholes.
>Perhaps it's time we drop the whole religion thing as completely unnecessary (apart from an excuse for old people to have a get-together and a game of bingo), and accept that science is all we need now.
Good luck with that.
contrary to what you have misconceived, my post you have replied to has no relevance with god, religion or higher power whatsoever.
it basically points out that this experiment may award us with the knowledge of what 'existing' is. all the 'otherwordly behavior' pale in importance when compared to knowledge of the concept of 'existing'. note i didnt say 'existence', i am talking about the mechanics of existing, or not existing.

The fact that you mention "old people" as if they were a foreign being and not something you will become tells me you do not yet know enough about life to make a decision on religion for everyone.
Being omnipotent means you can see everything, even if your back is turned. No excuses, no cop-outs.
Just to be pedantic for a minute, the term you are looking for is omniscient... And if you were, you'd know that...
I mention old people not as foreign beings, but as the pair of 80 year old parents I have to drive to said church bingo game every day. The age of my parents should give you enough information to determine that I am in fact plenty old enough to have made a decision on religion a long time ago (for myself).
And unlike religions in general, I have no wish to force my views on anybody else, it was merely a suggestion.
Just to be pedantic right back at ya.
Omnipotence from the Latin "Omni Potens" (all powerful). That would kind of imply the power of omniscience also.
Can someone tell me what might happen to the LHC in the event of a large solar storm along the order of the Carrington Event?
Beams dumped 16.34
Good while it lasted!
Finally had enough. Come see us over at https://soylentnews.org/
(yes im being pretty polemic about but everytime someone complains about "bad demographics" as a problem it just sends chills through my spine)
Actually you're just being less subtle about your disgust at racism than the OP was being about their racism (not that it was very subtle).
Anyway, my question is, how exactly does he imagine we're going to save "The West" without doing any research? When science and technology are among your big advantages, you don't turn around a decline by abandoning them.

The blogosphere has plenty on the LHC as you can see at:

You're reifying. there's nothing "not space". There's nothing to expand into because "expand" and "into" are not relevant when you're talking about space expanding. It's just the distance between things is getting bigger.
{PS think about "not egg beating", when you're beating an egg and stop. Where did the "not egg beating" come from? And where did it exist before then? And how big is that "not egg beating"???}
Because it could lead to the ability to assemble highly complex items from simple particles?
If you know how matter is put together, you're on the path to turning lead into gold.
Why would God not bthis to happen?
If they could get all of those little Muons inside the Inverse Femtobarn and close the door, it would be a lot easier to study them . . .

Where's the Kaboom? There was supposed to be an Earth-shattering Kaboom.
What religion is that, where God creates earth for man to make it into a paradise? The semitic religions, as far as I'm informed, believe that mankind will destroy earth and at last realize that knowledge/conscience, derived from Adam and Eve, was not a good idea.
...the "God" particle. WTF, does "GOD" have to do with it? It is the "Higgs Boson" and is theorized to be the Quanta of the Gravitational Force. Why it would be termed the "GOD" particle is beyond me. If you believe in "God" then every particle is the "God" particle.

Where are all the massive black holes generated by the LHC? Has anyone seen one yet?
Here's what Wilson said when Pastore questioned him in front of a Congressional Joint Committee as to whether particle physics provided any value to the country (and what Pastore meant was, did it give us any advantage over the Russians):
Only from a long-range point of view, of a developing technology. Otherwise, it has to do with: Are we good painters, good sculptors, great poets? I mean all the things that we really venerate and honor in our country and are patriotic about. In that sense, this new knowledge has all to do with honor and country but it has nothing to do directly with defending our country, except to make it worth defending.
So yeah, if you want your culture to basically be an animal culture, where your prime concerns are eating, sleeping, and shitting, where ignorance is held as a standard to aspire to, and everyone is essentially a moron and proud of it, sure. Go ahead and stop doing science.
Uh... not exactly.
The Planck units are just dimensional analysis wizardry; they make equations simple and pretty when you use them. By themselves, they don't have any significance.
Due to how the units were derived, though, Planck Length and Planck Time are intimately related: Light travels one Planck Length in one unit of Planck Time. Now tell me, how far does something with a velocity of 0.5c move in one unit of Planck Time? That's right, half a Planck Length. Now what if was moving at 30 mph? A small fraction of a Planck Length. Not everything is travelling at light speed all the time. That tells us that Space is not quantized. However, Time is still a complete mystery to us and for all we know, it could be quantized. But a quanta of Time would likely be much smaller than the corresponding Planck unit.
I've heard some people claim that the Planck Length is a future barrier on our imaging resolution, but their explanations either don't make sense or don't add up and I haven't been able to find any credible sources that touch on the subject. Regardless, though, from what they were claiming, the Planck Length itself was not acting as a physical limit on the Universe, but rather an approximation for the actual limit.
Look at the Planck Mass, for example. It is about 2.2 x 10^-8 kg (2.2 x 10^-5 g). That's roughly 22,000 times the mass of an average human cell. (http://en.wikipedia.org/wiki/Orders_of_magnitude_%28mass%29#10-12_to_10-7_kg) Not a very useful unit. Both too small and too large by several orders of magnitude for any real purpose.
Yeah, a pigeon with a piece of bread just doesn't seem to measure up to Old Testament standards.

"Old people", in such sense, usually means a state into which people put themselves in; not age.

And unlike religions in general, I have no wish to force my views on anybody else, it was merely a suggestion.
While "forcing" would be indeed deplorable, to improve situation a bit (I like to believe that we would be better off if larger part of humanity than it's currently the case had a realistic opportunity to free themselves from religions; larger part, but not all; we're not wholly ready yet) I think you have to use similar mechanisms, similar "brainfarts" which are exploited by religions. It's a competition of ideas, it always was; you can't put yourself at a disadvantage...
