LHC News - April 16, 2009 - Last dipole in tunnel

[Jacobrocks9900]

I saw alot of comments about anti matter in this section.. You probably all just read it in Angels and Demons.

anti matter were observed in a collider in conneticut, however it was only observed in a split second and in these collisions, nothing is certain, so cant really say anything for sure. but yeah it is a common theory that anti matter can make energy by annihilation, a process which takes matter and anti matter and they simply blast away when they collide, turning into pure energy.

[y11971alex]

Any message that promotes the destruction of the World by LHC whatsoever is false. The power needed to generate a singularity is beyond the measurement of electronvolts. Say, the 14 Tev generated by LHC = momentum of a flying mosquito, annd does a mosqueto ture into a singularity when it collides with another? of course not, energy neede to make a black hole exponentially exceeds our current capabilities, or that what we shall ever be capable of.

[crazywelshkid]

last year people were shitting themselves that this was going to destroy the world. Hmmm..... nothing happened... it broke... maybe the earth broke it on purpose!

[MaxEagle50]

xDDDDDDDDDDDD

[jared4wally]

WHERE DOOM I TOAD YOU DOOM 2012.

[JumpCheckProductions]

MILF

[SoundsOfDrumAndBass]

fuuck your yourmomiszero, its steven hawking who is a yank, and the people fucking us up and making us die are the swiss and the french

[Fjellmannen2008]

I cant believe they wasting so much money for this. I mean. Why cant the world remain as a mystery???

[wiez5]

i bet you wish electricity was never invented because that used to be a mystery too.

[prototype9000]

i would stick my dipole in her tunnel

[NickSayle]

I am really excited to see this project is back on track, with luck we will find out how pure energy becomes matter and the incredible transformations after the big bang. However what interests me more is to know what happened the Monday week before big bang and what lit the blue touch paper, Question, how many big bangs have there been????

[brando112345]

so r we all going to die in 2012?? :(

[Aaromsax]

no.. were going to die in august 2009.. :(

[borolad1993]

OH MAN it would happen when its my bloody birthday and when Middlesbrough start their ASCENT back to the premier league. LOL

[SlykeThePhoxenix]

Yes, so max out your credit cards now and starting living it up.

[Bloodsaberxy]

6:13 is the guy asleep? XD i would think so

[yuothineyesasian]

What happened Sep 19???

[solomsolomol]

they launched the collider and then a helium leak happened and caused damage to parts of it

[Lokussapiens]

when is the collision scheduled. when can we see a picture of anti materia? Pls keep the project updates posted:)

[yuothineyesasian]

there are already pictures of anti matter, it's nnot really a big deal.

[Lokussapiens]

really, so cern is not for proving anti matter? Only for the higgs thing?

[yuothineyesasian]

anti-matter isn't fully understood, but we know it exists. We've created it in other particle accelerators, and held it for some period of time. But we let it go because it is an extreme waste of time to put so much effort into storing it.

[godzilla74114]

no it isn't. thats one way to power a FTL drive. Matter/Anti-Matter reaction.

[yuothineyesasian]

I can't find my comment, what was it?

[godzilla74114]

about wasting time to try and store anti-matter. Or trying to develop a storage system.

[knytebyte]

im not worried about black holes...its the ass holes conCERN me

[Envergure]

If I stood in the tunnel when the magnets were powered up, would I be able to feel the diamagnetic force on my body?

[Hornet85]

8 hours driving that slow vehicle in the tunnel... wow, I cant imaging that

[Emamnuelguzman86]

No black hole is eating the earth up, as a matter of fact there are quantum black holes everywhere around you as we speak.

[higreentj]

The LHC should tell us what we are interacting with to give us mass, and if there are other dimensions. The Creation of black holes would act as a reference point in space time.

[bustacap503]

What a cool work of science and engineering. And what a pack of dumb fucks you say its going to eat the planet with a black hole when they dont know anything about physics. Its about as stupid and catholics throwing galileo in prison for saying the solar system was heliocentric.

[Sharpie600rr]

Agreed, I also cannot stand these closed minded people stating that this is a bad idea and we'll all die from a black hole forming. Do you really think these hundreds of scientists who've spent their careers studying this subject haven't looked into that possibility?

[FluffMachine]

agree too. I'm also upset at the fact that humans have become further away from space exploration and observation. they do not give much thought and time to space as it was in the past. long ago studying the cosmos was essential. predicting the cycle of planets, stars, etc was so important. We find out a great many thing through experiments like this and getting the human race out in space. imagine the possibilities of what we can learn and do as an interstellar species.

[yuothineyesasian]

The average person hears about atoms and galaxies and thinks it's all figured out already. The sad part is that it's so hard to get people interested in particle physics, they have to be curious about it already.

[AndreKhouya]

I don't like this experiment...

[azzy1990]

dont the c.e.r.n there playing with god the magnectic field will be to stronge when the components are filled with 2000 degree helium that could produced a black hole only small at first but when the magnectic mass is fuild by helium it will expand the black hole very quickly wich if that happens kiss our planent and galaxy good bye

[peacekid]

.....You have no fucking idea how a black hole works, do you?

Rchayes has it - it's a small black hole. It's going to deteriorate from the moment it starts, and it'll be so small you can't even see it with the naked eye.

[0TylerDurden0]

imagine it.. a fucking black hole so tiny u cant see it.. sucking everything.. every light.. every colour .. around u.. and... its so tiny . but its sucking the whole world outside in. .... how fucking epic is that?!?!?

[Firepaw123]

now thats fucking epic and i want to fucking see that!! xD

[niiidar]

you just haven't got a clue, have you? IF ou want to, I would happily explain.

[swinkyuk]

Forget physics for now, learn to write first.

[lacisnot]

haha.. why aren't you doing anything to stop it then? if it has the potential to destroy the galaxy.

Wouldn't your time be better spent saving the galaxy from complete destruction?

[pnskbk]

maby they'r thinking they are like luke skywalker

[YWA32]

to tell you the truth i dont no what is the purpose of this thing.

all i remember was people where saying that scintist trying to recreate the black hole.

so what is the point of this?

[grofuss]

What's the point? to "see" or reproduce very exotic particles which may exist in multi-dimensions... and we would observe these extra dimensions of space. It's the pursuit to understand gravity i.e. the graviton, which QM and M-Theory both predict as the effect we feel as gravity. The bottom line... if 'we' cannot directly observe a piece of nature, its philosophy, not science. Therefore instruments like this are a must to advance our most basic AND extreme knowledge of physics, chemistry, etc.

[AZURA888]

this is a nice video, without all that shity apocalyptic stuff that becomes to subjectionable people in morons, just spitting all class of nonsense curses against scientists and engineers whose built this marvellous machine and blaming them of all the problems of the humanity when scientist are not the 0,5% of humanity, that is really stupid. Maybe that's the problem of humanity, to many assholes already everywhere.

[Rchayes88]

Granted the RHIC didnt cause any problems, but it wasnt as powerful. They say cosmic rays hit our Earth constantly with greater force than the LHC but we have an atmosphere to reduce it into an air-shower, last time I checked CERN dosnt have a mini-atmosphere for their LHC. Also all the justifications for this experiment are based off of theories which no one has tested or seen in action. They endanger everyone, if only CERN would be destroyed, fine do it, but they hold everyones lives at risk

[HansTheAtheist]

@Rchayes88: I don't see the problem, and I think you're mixing up some unrelated things: first, the LHC is below ground, radiation is shielded by 100 metres of rock, much more mass than the athmosphere. Second, the cosmic radiation is not used to justify the radiation levels, but the risk of creating a mini black hole. If the LHC would create such a thing, it would have been created already in a natural way, and earth wouldn't exist.

[Rchayes88]

No it woulnt have, because our atmosphere stopped the protons as they pound earth, google 'air showers'. The collision of protons will not be disapated at all, it'll happen at full force and on earth so its chance of stablizing is greater than that of which the 'natural way' occurs. Maybe if CERN was incased in lead Id feel a bit more releaved. Black holes are like drains, once you pull the plug it will keep sucking things down. No astrophysicist has ever seen a black hole 'evaporate' or 'decay'

[HansTheAtheist]

@Rchayes88: If you would feel more secure when the LHC would be encased in lead, check out radiation protection. 1cm lead = 9 cm packed earth. So basically the LHC is shielded by the equivalent of 11 meters of lead already. Thinking that radiation can only be stopped by lead is a myth.

[uidsea]

Actually that statement is wrong

Most physicists today do say that black holes will and do evaporate. Im not sure where I heard it though, just look up black hole evaporation or something.

[yuothineyesasian]

It's called hwaking-entropy

[shon9514]

30 tons, over 1300 to change??!! No wonder they had to shut down for months! Congradulations !! Can't wait for new data and discoveries!!!

[Thoko21333]

unique and amwesome....love cern !

[pat2rome]

Man, how cool would it be to work with something like this?

[RIPEBERRY]

Right, lets see if it works this time!

[homousios]

soon. the Higgs!

[TigerLeahu]

.. or NOT, which would just open up the String Theory and extra dimensions.. Both finding Higgs and Not finding it are exciting!!!! Like opposing football teams Partcles vs Strings, the winner is the Game. ; )

[homousios]

you are right!

[validac2]

Perfect.!!

[lepermunna]

thanks for making these videos, looking forward to the next!

[TUFFCAT04]

"Will this tell us the truth about ourselves"

- I think so

- it's a chance for the expected and the unexpected, for progress even

- lots of scientists also care for these problems

- lots of money is spend to improve social and health-conditions and of course it could be more

- I also love organic :))

[MISSBESOS]

Will this help the crisis we are going thru, the starving people and the hate we started developing? Will this help understand the Globalization we are facing promising more suffering and chaos? Will this help us unite as a human race, as we are supposed to be. Will this tell us the truth about ourselves and not what religions tells us? ... Why don't they experiment in helping Starving people grow their food? I love organic :)

[aManApathetic]

There's your problem right there: wanting 'organic' and fed people at the same time. Humans have modified agricultural produce for thousands of years to feed themselves; almost nothing can legitimately be called 'organic' and some people seem to think progress can and should be halted now, for some reasons they hardly ever specify because they're patently ridiculous.

I know, let's cease basic scientific research and bring about a mini-dark age. That will help.

[cycik2001]

"Will this help us unite as a human race, as we are supposed to be? "

An international experiment that sits on the French Swiss border with scientists from countries all around the world working together to discover some of the deepest truths of the universe to be given freely to all humanity. It sounds like it already has.

"Will this tell us the truth about ourselves and not what religions tells us? "

I think that is what science has been trying to do since its inception.

[mazack00]

...it took the Cern guys nearly a month to edit this video then upload?

wtf...

[Dutchdrummer99]

Incredible. Can`t wait till it comes back online.

[gurkhaboy]

This is beyond Cool.

[milotintin]

Oh my how exciting!! I wish the team all the good luck they will need it!

[dmix09]

lets get it right this time shall we..

WOOO!! YEAAA LETS DESTROY THE UNIVERSE!!!

[effilang]

There is already black holes in the Universe - that doesn't make any sense.

[dmix09]

i know lol.. i was making fun of those gloom&doom people that think another "big bang" will result

[effilang]

lol - That makes sense now : )

I'm waiting for the aliens myself - sniff, Earth is getting so boring!

[dmix09]

hehe

[letdowner]

you guys seriously need to learn to spell 'break'. it's not 'brake', that's like stopping your car, 'break' is stopping it forever. i'm surprised you could physically operate a computer, let alone watch a cerntv video. kudos on raising the bar for legions of mouth breathers.

[theeskyyliine]

FINALLY! back in action!

[darkspinesonic5]

watch it brake again

[Ackreti]

"watch it brake again"

Its largest, most complicated machine ever built. Yeah, it can have some flaws from start.

[darkspinesonic5]

if it brakes a second time though they are doing something wrong

[youme1414]

Believe me, I am still sceptical of this project. It's fantasy!

[ferrariModenas]

pleaseeee smash these protons already!!!

[youme1414]

Maybe they will smash them at your door.

[KX125dude]

I think she said "19th of September"

[VerySeriousUser]

Yeah, I'm tired so I messed it up, sorry :P

[KX125dude]

No problem.

[cougar1515]

What happened to the magnets on the 19th?

[kurtilein3]

cougar1515:

worst possible accident... a connection between two magnets failed, got partially evaporated, caused shockwaves due to heat in the liquid helium, an arc formed, resulting flaws in the magnetic fields caused magnets to get knocked in one direction or the other, damaging many connections and magnets....

now they repair it, and install a safety system that will shut down the experiment safely and so rapidly after a failing connection is detected that this will not happen again.

[YousefNjjr]

By the time a failed connection is realized, the magnet(s) circuits would be toast. In other words, I don't think any such safety device exists.

[kurtilein3]

"By the time a failed connection is realized, the magnet(s) circuits would be toast."

when they inject new bunches of protons into the ring, they actually need to switch on some of those magnets, get them up to full field strength, and then switch them off so that the magnetic field and currency is gone again. all that in far less than a millisecond.

so the idea would be: a connection starts heating up, security system switches off all magnets and dumps the energy a few milliseconds later.

[kurtilein3]

continued to yousefnjjr:

i think they can be fast enough to get the energy out of the coils before an arc develops at a failing connection. if one connection rises in temperature over a treshold of lets say 5 degrees kelvin, how many milliseconds until it heats to the point of evaporation, arc and damage, and how few milliseconds do you need to dump the energy from the coils, switching them off?

[YousefNjjr]

They melted because a manufactures defect allowed the gold wires of the magnets to run 11 thousand amps without proper cooling.

[jwwetzel]

Fantastic!  Really nice presentation!

[ParadoxTorque]

Nice to hear good news. Good luck!

[teobesta]

finally the kind of good news i'd been waiting for

[Saukko31]

Cool, I have been waiting for you to restart the LHC.

[IC1101]

Good luck. Hope you don't fuck it up again.

[goldragon988]

Good luck! I'm really looking forward to the results of the experiment.

[Nickzed]

start that shit up!

[the768]

April 16th?

[Sum4life23]

good luck with the experiment;)
