A Decade of Discoveries at the Large Hadron Collider

It’s been 10 years since the first particles smashed into each other at the world’s biggest scientific experiment, the Large Hadron Collider. Scientists from each of the four giant experiments – ALICE, ATLAS, CMS and LHCb – reflect on what they’ve learned over the past decade and what they hope to discover in the next.

    1:02:00 So this is where all Nvidia’s 30 series GPUs are going.🤣

    I get so tired of actors and BS when the truths barely get divulged . Just a bunch of circle jerking with words to justify its existence . Thats all , 99 percent of these people make me want to get the back hand out 😉

    I would love to see an electron. WHAT! You don’t have one. You mean you cannot show me the teny tiny little BB;s flowing back and forth in the wires above my head. Trillions of dollars laundered and many generations of paychecks for the bean counters. But yet, not even a picture of an electron. Some great graphics and a dinosaur this time. WOW! How many times can you rip the people off. This one has got to break some kind of record.
    “To describe an electron as a negatively charged body is equivalent to saying that it is an expanding-contracting particle. There is no such condition in nature as a negative charge, nor are there negatively charged particles. Charge and discharge are opposite conditions, as filling and emptying, or compressing and expanding are opposite conditions.” – W. Russell

    JJ Thomson developed the “Ether Atom” ideas of M. Faraday into his “Electronic Corpuscle”, this indivisible unit. One corpuscle terminates on one Faradic tube of force, and this quantifies as one Coulomb. This corpuscle is not and electron, it is a constituent of what today is known incorrectly as an “electron”. (Thomson relates 1000 corpuscles per electron) In this view, that taken by W. Crookes, J.J. Thomson, and N. Tesla, the cathode ray is not electrons, but in actuality corpuscles of the Ether.” – E. Dollard

    “There is no rest mass to an ‘electron’. It is given here the ‘electron’ is no more than a broken loose “hold fast” under the grip of the tensions within the dielectric lines of force. They are the broken ends of the split in half package of spaghetti. Obviously this reasoning is not welcome in the realm of Einstein’s Theory of Relativity.” – E. Dollard

    “Unfortunately to a large extent in dealing with dielectric fields the prehistoric conception of the electro-static charge, the ‘electron’, on the conductor still exists, and by its use destroys the analogy between the two components of the electric field, the magnetic and dielectric. This makes the consideration of dielectric fields unnecessarily complicated” – C.P. Steinmetz (Electric Discharges, Waves and Impulses)

    The idea of electricity as a flow of ‘electrons’ in a conductor was regarded by Oliver Heaviside as “a psychosis”. This encouraged Heaviside to begin a series of writings

    Also consider the J.J. Thomson concept of the "electron" (his own discovery). Thomson considered the electron the terminal end of one unit line of dielectric induction.

    Awesome people, great video. Thanks TheRİ

    I am still astounded by what some humans can do when they work together (such as engineering / science projects like this). The human race should hold these people in the highest possible regards and do away with old fashioned beliefs in deities for which there is no actual evidence (books written by people that came after the rumoured events – a hundred years from now are they all going to believe that the events in the Da Vinci code actually happened because it was written down etc). Sorry if this causes offence to anyone – it is not meant to, but it is important to discuss areas like this.

    What if spacetime is fluidic, and the effect is only felt on the largest scales, could that account for some of the irregularities in galactic dynamics?

  8. Tracy_555 on April 12, 2021 at 10:59 pm

    what would happen if u put neodymium magnets on ur ceiling fan blades?
    this could be an affordable option for ALL so everybody can afford to have their own hadron collider too

    Is there any tests being done around the whole LHC and the testing chambers for fluctuation in gravity?

  14. Jonathan Lebon on April 12, 2021 at 11:12 pm

    Such a gift to be able to listen to (and try to understand) some of the smarts mind…true gems of humanity.
    Thank you RI.

  15. Vidyalankar Gharpure on April 12, 2021 at 11:12 pm

    I am not a science student. But I watched this very exclusive program out of curiosity. I admit, I could not grasp its contents fully. However after watching it thrice, I understood major terminologies referred to in this program to a great extent. I understood the expanse and importance of this LHC project. I humbly thank the entire team that aired this program.

  16. Jeremy Warren on April 12, 2021 at 11:15 pm

    Thank you so much for continuing to produce content! Love y’all

    25:17 hey they found a new particle in this lecture… the beauty quark 🤣

  18. Jacob M on April 12, 2021 at 11:15 pm

    This is so cool! I didn’t know it created the coldest place in the universe known by us humans so far

  19. Random Voice ie. Ian Tan on April 12, 2021 at 11:17 pm

    Just watched a video by Simon Whistler on his Megaprojects channel about the LHC, and it still blows my mind how little we have discover in this universe compared to it known knowns thus far.

    A wonderful 10th Anniversary indeed 👏👏👏

    Curved camera detector? Coming soon to a mobile phone near you 🙂

  21. bloody_albatross on April 12, 2021 at 11:21 pm

    So the current maintenance shutdown will last until 2022? Any chance there will be another CERN Open Days next year (after we all got vaccinated)? The last one was amazing, but I only managed to see a fraction of what is to see there.

  22. Debbie Culley on April 12, 2021 at 11:21 pm

    It’s be interesting to see the surpise on people’s faces when they get pulled into the black abyss!

  23. Peter Milanovski on April 12, 2021 at 11:22 pm

    10 year’s and nothing to show for it! Nothing! Made up imaginary particle name’s don’t count! All that money could have been better spent on more realistic experiments that could possibly achieve something real and useable, this is not.

  24. Paranormal Investigator on April 12, 2021 at 11:26 pm

    On displaced vertices and long lived particles that are particles which pass through the detectors are known to travel. hundreds or even thousands of thousands of miles travel outside the detectors to that which you are telling us is thus as the anomaly’s and we are are not told everything very clearly or straight foreword because CERN is not under control of these heavy long lived particles now if I understand your published studies in this area correctly upon reports I have read these heavy particles are unpredictable where their journey ends (displaced vertices) where & when they show up in our natural environment along side our created environment matter can appear out of nowhere a stream of matter from these heavy particles basically can end a journey right in front of your eyes inside you outside of you as the anomaly this is interrupted as discovery where the particles journey is found to end turning into some form of matter as a beam of energy this a gamble on someone getting hurt wouldn’t you think guys ????

  25. HamzOutFor HarambeBlessedBeHe on April 12, 2021 at 11:26 pm

    I had arguement once with someone who confused a subatomic particle collider for a kaleidoscope how one misconstrues a children’s toy for something that literally creates anti matter is beyond me.

  26. RiC Communications on April 12, 2021 at 11:29 pm

    This should go viral… but not everyone is a tech geek!

  27. peter lewis on April 12, 2021 at 11:29 pm

    100s of papers is not lots of discoveries , the biggest discovery is oooopps maybe were not going to find anything else..this looks like people desperate to justify the money when most real discoveries have been done in your head with pen and paper.

    So science is going the path of religion, sad.

  31. Peter Bhz on April 12, 2021 at 11:36 pm

    Can particles/fields go extinct? And if so how can we use that knowledge?

  32. Tooloose lowtreck on April 12, 2021 at 11:38 pm

    I can not understand what she says here, her accent is too much.

  33. Frogz on April 12, 2021 at 11:40 pm

    hahahah you all call it the biggest scientific experiment? biggest single piece scientific apparatus yes but i can name a few very long baseline infermetery(google it or watch the royal institution’s videos on the subject) arrays that physically are much, much larger as well cern’s CNGS project that is still to this day beaming protons from Illinois to Italy!

  34. Chichi Coronado on April 12, 2021 at 11:41 pm

    I heard Eric Kuenhle was building one, but in reverse..So it’s a Collider Hadron Large..Mans a genius.

  35. Peter Davidowicz on April 12, 2021 at 11:42 pm

    What a big chunky boy. 🧪

  36. Sacha Oneill on April 12, 2021 at 11:43 pm

    I shouldn’t have picked this subject for my engineering studies project.

  37. David Filer on April 12, 2021 at 11:43 pm

    Have they found the baby Jesus? I only ask cos I’s a Trump supporter.

  38. Max Headrom on April 12, 2021 at 11:45 pm

    Just a question: 5:50 I’m currently at a temperature much higher than -270C and I’m in the Universe. Is it correct to assume that the temperature of the universe mentioned by the researcher is an average? If it is an average, is it really possible to say the LHC is the coldest place in the Universe? Thanks! (So, this is a real question – it started with a rather lame observation but then my brain told me I know almost nothing and that I should check with the specialists … and that’s what I’m doing.)

  39. Kenjiro5775 on April 12, 2021 at 11:46 pm

    Nothing after Higgs though. These physicists are in a true existential crisis now. They are even debating the requirement of "elegance" in their formulations. Nobody in the field knows where to go now.
    Had to come back to say that the only direction physicists can go now is to pursue higher energy collisions. This means the cost of the next collider they will ask for will make the LHC look like the price tag of a dollhouse in comparison.
    Came back again to mention the notion of Naturalness as these particle physicists see the term. Ask your buddy the meaning of that term and then ask what it has to do with the scientific method. Then run, because they are likely to throw something at you.

  40. Mr-XeCute on April 12, 2021 at 11:48 pm

    Make sure your UK-representatives are still part of the greatest experiment on earth. A hard Brexit would mean a shut off of this experiment. 😉

  41. Mark Davich on April 12, 2021 at 11:48 pm

    7:04 "The LHC has to be adjusted even for the phase of the moon" – because it actually gets longer by a few microns? So… you discovered/verified gravity waves BEFORE LIGO?

  42. don17525 on April 12, 2021 at 11:48 pm

    SUSY entered the room! Or maybe exited, no one knows..

  43. Nathanael Newton on April 12, 2021 at 11:48 pm

    Wonderful video, Watched the whole thing.. it’s surprising that it only cost 4.75 billion $… That’s peanuts compared to some things we as a society spend money on, I’m going to use it as a comparison from now on..

  44. Sivan Sharma on April 12, 2021 at 11:49 pm

    Could not understand the second speaker. No offense intended

  45. shane mcdaniel on April 12, 2021 at 11:51 pm

    Okay so let’s say they figure it all out . So what does that mean? They don’t ever say , so let’s guess..time travel, warp speed, anti- gravity, proof of conscious after death, dimensions, make gold out of hay. My imagination can keep going, so let’s be practical with partical physics.

    "The LHC is so sensitive that is has been tuned to take into account of the phase of the moon, due to the acceleration ring lenght changing" whoa.

  48. mani mohamed on April 12, 2021 at 11:52 pm

    Doing a Great living scientific work at LHC , with risk , Hats Off to you all scientis ts over there ?Gods really with you …Dark matter or energy is a set of tools to fill the void of our thoughts ..let s search …heaaaaa….!!!@#$%***

  49. Fernando Aguilar on April 12, 2021 at 11:53 pm

    WTF was she saying?

  50. Abhishek Singh on April 12, 2021 at 11:54 pm

    Fascinating to know what LHC has been doing all this time. Very interesting video
