ATLAS - Episode 2 -The Particles Strike Back (Part 1)

[insectboy0]

wow

[lepape2]

Okay, im sorry but this device is so complex beyond measure, I can't describe the awe I'm feeling right now...

[HmsSulaco]

Find out more about the world...

[AshThEpSYcHo]

soo...whats the use of this any ways?

[cookiesonsteve]

THE JUPITER HYMN!!! I play that on the piano and the last time I've ever heard it was back in high school when I learned to play it! What is the PROBABILTY of that?

[bellinivernon]

Exelente canal ! ; gracias ,desde argentina...

[awsomeskilz01]

reading your comments criticizing something so revolutionary, out of pure ignorant fear, makes me laugh, go read a book and do some research and then make an opinion....dont call something stupid when you have no clue

[delteronix]

I agree with you sir, the biggest reason for the state that our world is in now is because of plain evangelic ignorance!!

the amount of recently discovered facts that the ancients knew is ... well.. staggering!

[landmacht]

i dont understand???

were in a world crisis right?

and how much should this stupid black hole earth destroyng think costs??

omg we human are so stupid !!

[TonyFirelli]

5:25 LMFO!!!!!!!!!!

[birchthebirch]

why use mars teh bringer of war !!!! lol please have already skeptisised about these machines and how there gonan bring death ot the world and the human race. funny

[fordxg]

Can some one tall me if this things working yet , I no that they had problems with it....:-)

[ANewHopeIll]

there is more to this that what there telling us

[pukaman2000]

You should have been able to discover this in the first 20 seconds.

[SHAMIRMCLEISH]

thats so cool how they use Si atoms which get positively charged from the charged particle and the Electrons released from the Si atoms form a current which tranfer to the dector:)

[KIMdante]

why don't they do that in space ?! i know it sounds crazy but also safer than forming a black hole in the middle of the earth u know

[Hedgehogs4Me]

I'm guessing that it really doesn't matter where you form it, if a black hole gets to the point where it can expand at a steady rate, we'd all die anyways, no matter how far away we could put it.

Also, would cost a LOT of money to transport all that to space and get it into orbit.

Don't worry though, the chances of anything like a black hole forming are VERY small, from what I've heard.

Note: I am not part of the ATLAS experiment or any part of CERN, I'm not sure of any of this info.

[wisdomwild83]

i think the chance of anything like black hole forming is not very small. what if they something wrong with the machine and will make the black hole unstable and expand with it's own will. it is not possible even our technology can't predicted about that. look what happen to chernobyl nuklear reactor accident. don't to confident about our technology sometimes technology is not perfect like human.

[pukaman2000]

There are other things that have higher probability that black hole formation.

[TAz69x]

Micro black holes are constantly formed and decaying in many experimental colliders on earth. Aside from the physics of micro black holes, generally black holes have a lifetime; Hawking Radiation residing as an amazing discovering of the physics of a black hole, once thought of as an event horizon for physical baryons to essentially be lost to this universe. The smaller the diameter of a black hole, the quicker the decay rate.

[Stano87]

I wait many years for LHC results, and now when it should work, it has troubles. Well, I wish all people working on LHC strength to overcome all dificulties. And I hope LHC will bring us results, that will revolutionize our understanding of nature, as soon as possible.

[shp0ngle]

yeah. if this does not give us deep knowledge, i agree. if nothing happens. waste of money when there are people that dont even have clean water!

[farvision]

shp0ngle. Certainly clean water is important but so is gaining fundamental knowledge. Should we study how a virus is unable to grow well on a strain of bacteria, but when does grow, it can grow well from then on? How obscure can you get? But that weird little effect was the discovery of restriction enzymes, which opened up the entire field of genetic engineering leading to thousands of medical advances.

[Bugstomper2]

Creating a negativly charged meta-stable stranglet, is highly unlikely, and is akin to making an ice cube in boiling water! The strangelet needs a cooler surrounding temperature that itself to become stable. Now a black hole? That is another matter. They're betting on Hawking Radiation to dissipate it. But HR has never been officially observed. They're going to send up a satellite that is specifically designed to detect HR. So why aren't they waiting, to get Yay or Nay confirmation?

[andriy600]

god dam it how old r u guys im 11 and i understand everyword

[Ingmatter]

The experiment was done a few days ago already, They are still studying the leftovers of the result from the protons colliding. you are complete idiots if you think it was going to actually do something destructive, besides that thing is 300 feet underground and its a man made model of what we believe to be the big-bang. So it wont have the same effects, not to mention i heard they were trying to break the protons to find a new sub-atomic particle.

[pschaffner74]

What was done on the 10th was just a test of the LHC beam, not part of the experiment. The experiment will run for years as they test many different theories. Also, there's less chance of creating a strangelet or stable black hole than there is of finding Jabba the Hut in there.

[petesonlineok]

one thing for sure guys, one day you`ll find out for sure if there is a god or not?.. (to late then).

[Vaporifix]

Yes, let's remain willfully ignorant.

[GAKUSK]

Stop arguing over the existence of God. Science does not the absence of god, rather, many scientists don't believe in God because they have no proof. It doesn't mean they need to directly see God, or that they deny the possibility they just need some point from where they can make a reasonable deduction to His/Her/its existence. Equally, many scientists believe in God and Particle Physics.

[spmoura]

Damn, what about them neutrinos? I wanna know about them.

[Andys184]

There is no such thing as GOD or GODS it's make believe fairy tails for the kids that is why there's a Bible to keep them from believing in the truth kind of like our government.

[No1RobLoweFan]

Today is a red letter day!

[ZOKITAPANAR]

10 september in 5 am

[MartinMusic1]

They're using music from Neverwinter Nights!!! XD

Anybody knows wether this piece is made specially for the game or the developers took it from older composer??

[rezomatic]

It's pieces from "The Planets", by Gustav Holst. Just a very famous symphony suite.

[retr1but1on]

what if this collision creates exactly the same range of particles the LEM created just ... 1836 times denser :). That would be a waste of effort.

[donisalexandru]

but what if those protons and neutrons will go trough the tube????

[donisalexandru]

when will this satanicall device will be tested ?

[PsychedelicSodaCan]

wednesday GMT time 8:30 AM i think

[diavolu28]

10 september

[lukehol14]

If it happens, it happens, we're all going to die at some point, it wont hurt dyeing from a black whole anyway, we could end up somewher else for all you know (theory of their being other universes on the other side of blackholes) we'll be ripped apart so fast we wouldnt know about it ;) and i doubt it will happen, hawkings radiation will dissolve it before it gets big enough to swallow earth ;)

[D3mi4n]

That's just ignorace talking. WE WON'T BE SUCKED BY A BLACKHOLE AND NOTHING LIKE THAT.

Is just the pseudo-scientist scaring the not-PhD-in-physics people.

[gina0o]

no body knows for sure if hawkings radiation actually exists - that is partly the reason for this experiment to take place, to see if it does exist

[lmjames33]

GOD is TRUTH and man should bow down and stop denying him. We are always trying to prove GOD does not exist and still to this day they have been unsucessful! LOL...... We can be sucessful in being dumb asses that don't deserve to be here!

[Ceonsamea]

Nobody has proven him to exist either. Both sides have an argument for life and gods existance, but neither has proven the other wrong, so stop being so ignorant and offensive, let people believe what they want. Besides, who said this was to disprove god anyway?

[pschaffner74]

Can't your god take care of himself? Why do you feel the need to defend him? And why is your god so anti-science anyway? Science is not anti-god, and by your default created by him anyway.

[boomanja1]

are we all going to die?

[snozzcumbers]

yes

[badger1211]

scientists are so concerned whether they can and cannot they forget whether they should. how dare they even risk the only life in the universe. if it was one in a billion i wouldnt go near it. Life is to valuble.

[eduardvictor]

we are not the only life in the universe, that is a selfish idea made by stupid people that believe in God...

[GeneralAnimator]

agree!!

[bigbadbom]

WE ARE GOING TO DIE!!!!!!!

[vagelas1gr]

congratulations cern!!

the experiment has been named atlas..

do we know when the big bang will take place??

[clucer]

We should at least be working with the EU on all scientific subjects. Why throw away good money on experiments others are going to do. I cannot understand this. Bush doesn't mind bullying NATO to come to his aid in Afghanistan. NATO has not been attacked. I hope Iraqi partisans smoke those wells in IRaq. And guess what George your not gonna get a drop of south asian oil. Can you say Russia, China, India, Iran. Did you see him drunk at the Olympics? I guess he gave up sobriety.

[defproc]

Do not boost the muon spectrometer by 105%, no matter how badly you need the extra resolution. You have been warned.

[azteca7026]

8 8 2008 mucha coincidencia no creen?

[eivissano]

horndog1014,

The LHC might just help us explain how exactly gravity works, which in turn might tell companies how to actually develop and build BTTF2 hoverboards. Ever thought of that? I betcha didn't. So, next time, first think (some more) before writing. And do go read some good books about particle physics.

Oh, and gee, what "benefit to mankind" would BTTF2 hoverboards have?

[clucer]

What gain from being an ass?

[rea1001]

the scary thing is, this inane rubbish was congratulated.

[horndog1014]

Complete bollocks.... I think scientists and other geeks should stop wasting time and money on worthless experiments like this. I mean they should have spent all their money and effort into something of benefit to mankind like developing hover boards like out of Back To The Future 2. I mean admit it, what would you rather have, a big machine that can smash protons into each other or a kick ass hover board to go cruising round the streets with?? Not the hardest choice in the world eh?

[areu1rustynail]

if it was left up to a fools like you we would still be sitting in caves ,no lights and no fire...just your thumbs up your butt

[markangeloc]

Instead we are now sooo sophisticated, having a ball with wars, eliminating classes, creating viruses, focusing on all external materialistic things that will lead us to our extinction. We would have been much happier and healthier inside our caves, mining our own business while becoming enlightened and one with all that is. I believe we did more than just having our thumbs up our butts, but they lead us to believe that is all we did, historians are bought and paid for by the elites.

[wowthungsten]

On the other hand, it is much more useful to fight wars of aggression which, since we're mentioning costs anyway, would burn through the price of this magnificent device in slightly under two weeks time, causing nothing but pain and untold misery as a result.

When it comes to challenging our understanding of the universe however, it costs too much money, because -you- don't understand it.

DNA said: "The secret is to keep banging the rocks together". Please, do so until enlightenment ensues.

[dismart]

The problem is that this is an experiment, they really don't know what will happen when this machine is fully powered up. anything 100,000 times more powerful then the magnetic field of the earth can't be fully contained or stopped if they lose containment.....lets all pray they don't destroy the planet

[zcherus]

Um, no they won't. May I smack you in the face please? Just once.

[Standard999999]

No, the scientists would not purposefully destroy the planet! But they might do it by accident and they might take risks that are much much higher than they are willing to tell you they might. Just like the managers that recommended Launching the Shuttle Challenger did not believe that it would explode. They knew there might be a reasonable risk because their engineers told them there might be a reasonable risk. But the managers said (paraphrase) "there is no proof of reasonable risk... launch!"

[areu1rustynail]

run chicken little the sky just might be falling

[kentaresquah]

Do anyone know the music/score played from 1:22 - 2:55 ? Its so good

[weejockpoopongmcplop]

That would be Jupiter by Holst.

[DarkBaum]

This extract from Jupiter by Holst is also used as the melody for "I vow to thee, my country". I love it, too :)

[driftability]

What will mankind benefit from this experiment?.

[Lastesina]

Knowledge

[Bratbaticus]

If the human race manages to last until the end of the universe we might find some way to, I don't know, not die as fast.

[zcherus]

If there wasn't for particle physics, You would not have your shiny monitor to ask stupid questions, nor you would have mobile phone and many many other things that you probably can't imagine modern life without. So yeah it will benefit humanity, but don't think about commercial applications, they will come with time, we need more complete knowledge about universe first.

[clucer]

There is no point in being snotty about particle physics or any other subject. You just piss people off whose friendship you may need someday.

[LECHEROOOOO]

when?

[sk8rdude891]

are you serious? will it contain the energy its alot of power u dont know what youre doing!

[dzec82]

The experiment is colliding particles with energies of about 7 TeV that the amount of energy a fly has when is colliding against your windshield. However the entire energy of that fly is concentrated into one subatomic particle, higher energy density, yes; more destructive, no. The big bang involved the entire universe, you cant recreate the big bang. here we are recreating the same energy density. In the eyes of that subatomic particle the conditions are similar, thats all we care about.

[squishdude]

If u ask me.

it just seems like a giant bomb.

more powerful than anything ever created in the history of the universe...

oh except for the big bang ^_^

[squishdude]

and they think the travelling of particles after the collision will stop inside the machine? lol.

We are all going to die if this takes place.

[Mattnesss]

"and they think the travelling of particles after the collision will stop inside the machine? lol."

No, they don't think so (have you ever considered that, y'know, scientists could actually know what they're doing?). Anyway, I have a very easy question for you. Why do you think the LHC is roughly 100m underground? I'll give you a hint: It's not for convenience.

[radienx000]

Lets hope the Scientist created a Backspace button or an "Esc" button to stop anything from going wrong. xD

Actully i think, if im correct, they make another big bang, it wont be quite a physical impact, but more like the they will "Upset the Natural Balance of Matter in the Universe".

[Owen2rules]

wow star wars nerds and scientists,yes that matches

Na na na seriously that was awesome and i hope they dont blow up half of the earth!

Good job!

[lfbothner]

My only concern is.. I hope they didn't pick the lowest bidder in supplying the components. This is too big to worry about cost. REALLY!! 16 billion is a bargain

What will come of this will change the world in Everyway imagineable.

[Xenogalatica]

it'll be a spectacle to witness i tell you.

[Maxisgirl]

I would lmao if a fly actually did get inside the -270 degree vacuum. And I hate to rain on your parade but even after this happens and nothing goes wrong it will take us years to analyse all this data.

[negativeheatcapacity]

The energy of the full beam at maximum acceleration will be about as much as that of a small aircraft carrier (20,000 tons) moving at 30km/hour. In Earth's gravity, 30km/hour (or 6m/sec) is the speed you get when something hits the floor if you dropped it from 1.8 metres height (~6 ft).

Last I checked, it wasn't possible to blow up the Earth by dropping a small aircraft carrier on it from 2 metres away. So, not to worry... :-)

[ShtefT]

what could posibly go wrong here :))

[Harabec23]

I'm concerned about being converted to strange matter. :(

[Owen2rules]

hey then we can fly!

[SKatial]

man more people need to be aware of this in the world.. 12,000 views?

[jamesthq]

these guy's know what their doing dude. Were not scientists or partical physists so I know when I'm in way over my head.

[Theschwager]

Am I the only one worried about a black hole or a big bang that annihilates the world and everyone on it...

[FelleAndersson]

Don't worry, when it happens, you won't feel a thing ;)

[StefSSU]

Star wars theme was a bit cheesy, but awesome vid! keep it up!

[blackbass0]

this is the particle accelerator sciencetist are trying to make a mini big bang theory where protons collide in the speed of light

[StefSSU]

ALMOST the speed of light. no particle with mass (no matter how small) can accelerate to the speed of light, because as they reach the speed of light the matter's mass becomes infinite, requiring an infinite force to continue accelerating, and there is no such thing. They are re-creating the moments about a billionth of a second AFTER the big bang, not the bang itself. they are searching for the Higgs particle, the particle which gives matter mass.

[Testerer004]

that's where united physicians, chemists, mathematicians, engineers and even computer scientists will work for probably the most important and tremendous experiment ever done!

Let's hope this will benefit us all.

[coronapounder]

if we dont destroy 2/3 of our earth we have succeeded!!

[soldersucker]

Few more months. Bad news is experiment data will not be available to the public so you will not hear of any discoveries until they officially publish their discoveries. They are doing this to so morons in the general public will not publish false papers or claim they found a breakthrough.

[silentstorm32]

When they hit the start button? I cant wait for see it!

[kurthess]

Now THIS is the type of science video I've been looking for!

[09205479428]

The FERMILAB is doing thesame experiment and another one larger is being built.. i'm not sureif it is this ATLAS project. Hey guys did you know that a blueprint of photon accelerator was made much earlier than our modern age.. much ealier than the birth of Quantum Physics in India.

[ytmoog]

Fermilab have a similar collider which has been running for quite a while, but the LHC will be 7 times as powerful.

[chuck4842]

If Fermilab has one and they didn't find what they wanted, than does that mean they'll build another if this one doesn't provide? I don't get it.

[soldersucker]

Cant wait. Its almost finished too.

[VanDub]

i know what they're saying is important, but i'm just not gettin' it. What are they trying to do?

[weejockpoopongmcplop]

They are trying to figure out how the Universe works.

[StefSSU]

They are trying to find the Higgs particle. The higgs particle is what gives matter mass, in other words, what makes stuff... stuff. There are many potential breakthroughs and experiments that the LHC will be capable of, but this is the main reason it was built. they are searching for the last particle to complete the Standard Model of the Universe. They have been searching for the Higgs particle for almost 50 years.

[devadip1]

Awsome, The brains of the people who figures this out, wow.

[versat82]

thanks, that videos are made so great and are very interesting for me

[pbrane]

Omg - wow!

[REDG2074]

Amazin'!

[Mattersmatter]

well done and very informational

[DoubleM55]

Awesome!

[sheepwshotguns]

incredible, thank you!
