"the more we discover, the less we actually know" Great quote. Reminds me of "A wise man knows he knows nothing"

I'm glad an organization finally tries to capture the emotional element of this kind of work. If so called normal people understood the motivations behind science, people would become more interested in how it's done.

@TheOats Sure, this is one of the big problems in all experimental sciences. Most observation instruments and practices can interfere withe the phenomenon you are observing, and bias it. Our detectors actually do the opposite: they purposely introduce bias, like a magnetic field, and then recognize particles by the way they behave under that bias. Alternatively, some particles are recognized by the energy they release when disintegrating against the layer of the detectors. SdG

@Hornet85 The CERN Computing Centre features about 10,000 CPUs, dedicated to processing LHC event data. This represents about 10% of the LHC computing needs. The Worldwide LHC Computing GRID (WLCG) in fact spans well over the CERN site, including 140 computing centres around the planet. Projects like Folding@home etc. use a volunteer computing infrastructure, called BOINC. There is enough spare capacity on BOINCs to run without the need for GRIDs. SdG

Apologies about no sound on previous upload of this clip. Had used a weird codec that YT didn't like. Silvano (producer)

Understatement of all time: It's amazing to think that prior to the existence of this Universe that there was an even greater mass of 'something', 'somewhere'. Whatever that extremely immense mass was *we* were like a drop of water on the surface of a balloon the instance that it popped. The incredible mass broke where it was and spat us out, a single drop, from where we were (not through Time and Space, but from _existence_ to _existence_ from there to here). Presumably other _drops_ spat out in all directions into other _existences_ creating many Universes in many places. Our _drop_ (more than all the matter in our Universe, yet smaller than a grain of sand) spat out like a Great Horn - the Trumpet of Creation. Expanding instantly, like a quadrillion Nuclear Bombs in a super vacuum, pure heat and light exploded into what was prior to Life forming early Matter, some of which decayed, becoming what is today. Not only is there our own Universe to travel but also the other places created when we (our Existence) was born. Surely the first moment the mass of our Existence traveled faster than Light, as "Light" did not even exist _here_ the instance prior to our existence. Need some new Math skills.

Good work. @ 2:35 , the announcer reminds me of Carl Sagan. Great presentation skills. She should get her own show.

Thank you for sharing this. Well done.

This is wonderful!!!

Awesome, Thank you very much for posting!!!

@Keovar OK, let's talk philosophy. We call "normal" matter what we see around us (and inside us), and "anti" whatever looks "opposite" to "normal". This discrimination is of course a convention, established from our viewpoint of reality. Antipeople on an Antiworld, if such thing exists, will also do the same, that is, we are their "anti". Signs are also a convention, as magnetic poles. Is there a functional difference? that's what we're trying to find out! SdG

Beautiful, indeed.

This was great! Please make more video like this!

@Aresftfun There are many national Particle Physics laboratories around the World. In the US there is Fermilab, Brookhaven, Berkley (LBL) etc. Most of our scientists are based in their national labs, and come to CERN to share knowledge internationally. At CERN we also have other non-LHC experiments, such as an antimatter factory (AD), isotopes experiments (ISOLDE), a Neutrino experiment (CNGS), a neutron facility (n-TOF), and a climate physics exp. (CLOUD). Check our website for more. SdG

Love this. Love it. Love love love.

i am in awe at the work these super intelligent people do at CERN. well done and goodluck in the future!

@Jazobsen Yes, that's one of the theories. No sign of Higgs yet, but we're patient. SdG

As CERN Guide, I have to say, A Great Great educational video. Congratulation collegues!

@CERNTV Is it just precaution to keep people off the underground area, or is it impossible to be around the machine while its running? too strong magnetic fields or danger with helium? I wanna see it too!!!

@Keovar You are correct about the need for an almost perfect vacuum, in our experiments. The vacuum in the LHC is 10 times emptier than on the moon, and that's as you say, in order to "remove obstacles" into which particles may bump. In our Universe there is no "visible" antimatter so far, let alone a whole galaxy. We are about to launch an antimatter detector (AMS) that will be installed shortly on the International Space Station, to look for any traces of antimatter in space.

How do you see the antimatter? What are the results of the experiment? Is antimatter the concept of 'selectons' for example super symmetry?

A tear of emotion just ran out my eyes. Science is the only way, and what you have achieved is perhaps one of the few things that makes me be proud of being human (I know, that's a little bit simplifying but I don't think there's much to be proud of). By the way, I find it very stimulating that in the images you can see young people working at it too! Greetings!

woa entertaining and very informing at once, really good work ...thank you :)

@primate52 Back in the 1960's when the basic research on lasers was being done, nobody had an idea what they could help with. These days they are used in hundreds of applications for measurement and data storage, and we've certainly not exhausted their possibilities. Benjamin Franklin used to answer this type of questions on basic research with "what is the use of an newborn baby?"

The beauty expirament was left out of the video. In fact it involved all employees lining up and rating eachothers beauty. Then corrlating those scores

Great video, Thank you! :)

@mathforphysics "Only integrals", yes. But many of them are complicated enough to fill the working life of many theoreticians. Most LHC studies use hadrons somewhere (if not in decays, it is still a p-p-collider...), so QCD is included if you look at the process in theory.

@antipodeandreason Yes he is still part of the collaboration. ATLAS is a general purpose detector aiming to find any new particles that could enlighten us on the formation of the early universe, a fraction of a second after the Big Bang. The origin of mass, supersymmetry, dark matter, extra dimensions are some of the mysteries on the menu. Google Atlas Experiment for more info. SdG

@BurnabyAlex Tara is a great science communicator and a lecturer at Liverpool University. She also works with the BBC and other TV channels. SdG

Does CERN open the grid computing thing to the public? Perhaps something like Folding @Home project where the public could help run the simulation on their own computer to analyze stuff.

just wondering."Is it possible to take a tachyon formula with the results of matter and antimatter and fiqure out the fractionalisation in 3 dimensions?

Glad to see the smartest people on Earth get smarter!

I really hated it when they renamed the Truth and Beauty quarks to Top and Bottom. Probably the same committee that kicked out Pluto.

@OtherVerse ok, so you are making a fuss over some inappropriate wording. I looked back at the script and found that the initial version said "than anything ever achieved". However that line was modified during the shooting. Tara is not an actress but a physicist, and does not recite the script by heart. The lines on the paper are just a guideline. Perhaps that particular one came out of her head without thinking of cosmic rays. Apologies, nobody is perfect. Silvano

@geromino2007 All of what you mention, plus radiation. When the beams are on, there is high radiation in the tunnel and the experimental caverns. This radiation is however entirely contained within the thick cement walls. That means it is perfectly safe for us on the surface, but you just cannot be in the underground areas when the machine is running. SdG

@OtherVerse You might be right about that, however our communication policy is simply based on "telling the truth". If this machine produces the most energetic collisions ever made by man, we will not hide that fact because of a few delusional whistleblowers. The fact that cosmic rays collide everywhere, including inside our body, at much higher energy, is our main argument. Those who have a brain and want to listen, will. SdG

@Jcapmusician1394 yer but the construction probable changed events more then the collisions and acceleration will disregarding what we will learn from it.

Now I understand why it is named as it is

@BoardOfRandomosity I don't think so. The name GRID comes from the analogy with power GRIDs, as computing resources are dispatched across a GRID a bit like electric currents over a power GRID. There are hundreds of GRIDs around the world, for all sort of computing. You use at least one of them every day: GOOGLE. SdG

@BoardOfRandomosity Its basically a form of cloud computing...there are some NGOs wherein even you can hook on to the network and assign your computer's idle time for the cause of medical research etc

Is the name of the supercomputer a tron reference? The Grid.

@mathforphysics Use publications and conference notes&talks if you look for scientific results. The theoretic part is mainly quantum field theory, which is not just "some math".

What a great report on LHCb - beauty-ful! Andreas, how are you?

@mathforphysics Up to a level that they could calculate cross-sections for e- e+ scattering on their own, for example? LO, NLO, NNLO, ...? And I think we agree that e+ e- scattering is one of the easiest things with "real-life" applications. Throw in some QCD and you get the real mess.

The universe has been exploding for billions of years, or/and is it expanding a lot in the space ?

Mientras más se “avanza”, más se descubre lo poco que realmente se sabe. Poco a poco la física moderna se ha ido acercando a la humildad y pasión socráticas. Son nuestros modernos “alquimistas”, sólo cabe preguntarse si se darán cuenta de ello. Que leyeran el libro Psicología y alquimia de Jung podría ayudar en el acercamiento de las áreas del conocimiento físico del mundo junto a las humanidades: porque la vida ya nos está demostrando muy obviamente que esto nunca ha estado separado.

I'm still excited about all this. I hope we can find the collision that will give humans super cosmic powers.

@Henysheadonwall I agree, wholeheartedly...

@sbkang85 Yes, the video was comparing CERN's energies to the maximum particle energies achieved at Fermilab's Tevatron. But the video DIDN'T say that. That's the point I was making. Consider this: even major media outlets constantly repeat the LHC "doomsday" garbage. The reporters hear about energies "higher than anything seen before" and "mystery of antimatter" and they misinterpret it. It's irresponsible to encourage such misinterpretations with such careless choices of words.

I think Tara Shears sounds surprisingly like Professor Brian Cox - I don't know if it is a horrible thing to say that someone from Liverpool sounds like someone from Manchester.

I see the girl at 1:07 is already pondering the physics of traveling waves

I think the biggest mistake in world physics is that some of the most talented people in the world don't choose physics. Including me. Maybe I could create a force against gravity.

@noxure , Physicists will say "pure energy" as a shorthand for "photons", because photons have zero rest mass. But in general, your comment is quite astute: you've noticed that the video is actually quite abominable at explaining anything. I might try to have a word behind the scenes with Silvano, to discuss the video's omissions and misrepresentations. For example, it's plainly wrong to say, "7 TeV, 3.5 times higher than anything seen before," since cosmic ray particles can exceed 1000000 TeV.

@ADEdge how many partical physicists does it take to change a lightbulb! forever! they're too busy WANKING!

@itsasin1969 You can't see the big bang by looking 13.7 billion light-years into space. Look up "cosmic microwave background". You can see long-gone quazars because, when they existed, they were distant from us in space already, and the expansion has made the origin of those photons farther. But the big bang happened everywhere in the universe, and any singularity also existed everywhere, because, at the time, the universe was a point.

.34 "Something that will change our view of reality..."

@reefgirl994 Not at all, that was a very good question. Just trying to cope with the assault... Those particles are so small that gravity has very little and hardly measurable effect on them in a lab. What matters to detectors is charge. The AD experiments use magnetic fields to "suspend" antiprotons and positrons to observe the formation of atoms of anti-hydrogen. Google ALPHA CERN, or ATRAP, or ASACUSA for more. SdG

@Jcapmusician1394 Super cool story, bro.

2:04 to 12:31, and to boldly go where no man has gone before.

@happysplodie Then you should plan a trip to Geneva for Jan 2013, as that is next shutdown when the underground areas will be accessible. SdG

Cool. Science.

Is Prof Brian Cox still working on ATLAS and what does the experiment aim to find.

This video was uploaded in 2011 and was obviously made before that time. As of 2012 the first few runs resulting in what appeared to be B_s mesons took place. The most current data I can find is from 2013 where, iirc, a Sigma Level of 3.5 on this type of CP Violation has been reached. That level alone is quite staggering but I anxiously await further developments for 2014. Kudos LHC!

Shes lucky shes so smart, because my god shes plain to look at.

Beauty = the bottom quark?

@AlienFromAntrax You thought you could correct me, because you *felt* that you knew all of the correct definitions of the word. However, the correct definitions exist in dictionaries as a matter of *fact*, and they show that your feelings were wrong. That in a nutshell is what's wrong with this video: the production team *felt* that they knew the facts, when in fact they made a train wreck. Now the producer is trying to defend their inexcusably sloppy approach, which makes it far worse.

@primate52 How is understanding the basic underlying principles of the universe going to help us? What? Why would you even have to ask such a question? I bet if you were back in the 17th century, youd be one to go on about Benjamin Franklin wasting his time with that 'electricity' thing. As if thats ever going to do anything for us!

@primate52 We can't afford to waste money on crossing the ocean, Mr. Columbus, when Spanish society has so many unsolved problems. Why, most of those Jews and Moors we have converted aren't really sincere Catholics, and a lack of money to hire more inquisitors has put their hearings so far behind that many have died of natural causes before we ever got around to them. - John McCarthy 1993

@raddicks1 Real mature troll...

What is "pure energy"? She's saying it so casually, but I'm not buying it. Energy is an abstract concept, like "fruit". You can have apples and mango-juice, but there's no such thing as "pure fruit". Likewise, energy can be a property of a particle or a quantity of force, but the concept of "pure energy" just seems to defy all reason.

messiahh is arrived,MUHAMMED IMAM AL MAHDI,

CERNTV i like you and all but you seem to like arguments

@CERNTV Silvano, no one needs an apology about that one line in the script. If you should apologize about anything, it is your entire attitude toward your mission as an educator. You're still sounding like an egoist, even in your supposed admission of error, by referring to me as "making a fuss". You and your team should be ashamed of that. You should view the CERN imprimatur as a demand for excellence in your team, not as a shield to cover your team's incompetence. Just go. Leave.

11:00 "With different religions" -- Yeah, like 95% atheists and 5% agnostic.))))

@CERNTV Silvano, there's no argument. You are trying to defend things that are demonstrably wrong. You fixated on that *one example* about cosmic rays, but you still ignore the reason I provided that one example: to illustrate your contempt for accuracy. Now, egoist, you imagine that there's an *argument*. Your KZread defenders are now following your example, deriding scientific accuracy as "pedantry". Was this your goal as as a science educator? No, it means you have failed.

@MicrosoftsourceCode Stop being so boring! haha

And now JWST has proven the big bang was not the start......😂 so big waste of time.... now what?

@CERNTV Silvano, your reply marks you as a egoist, not an educator. Shame, shame. I am quoting your video's script here: "7 TeV, 3.5 times higher than anything seen before." Your video did not provide the viewers with context to interpret that. That's so self-evident, it's almost absurd for me to have to tell you that. Stop being a scoundrel in public, and recognize that your video wasn't "telling the truth" to the intended audience of non-scientists. The script was terribly inept.

Lots of supercolliders going up, pretty cool!
