The humble proton may seem simple enough, and they’re certainly common. People are made of cells, cells are made of molecules, molecules are made of atoms, atoms are made of electrons, protons, and neutrons. And protons are each made of three up or down quarks. Simple stuff, right? All except for that last part. Protons are actually made of many, many quarks that happen to look like three only when we look at them in a particular way. And even then, sometimes they’re made of 5 quarks - including the charm quark.

  • @noxfelis5333
    Thanks AI for telling us that we all contain intrinsic charm.
  • @im_piano
    What's great about these particle physics experiments is that we're unlikely to run out of protons to disassemble in the near future.
  • Thanks for explaining how machine learning is used in particle physics. This whole series is a rare gem in YouTube.
  • @philmccavity
    This is so well explained and yet so packed full of great details. It's overwhelming in a positive sense. This series deserves every educational award out there.
  • @Desertphile
    Well, I dunno much about protons, but Bing told me The Big Bang was an explosion, and when I told Bing it was actually an expansion, Bing told me to change the subject. I still have the feeling that I hurt its feelings.
  • @pbsspacetime
    Update: The audio problem seems to be with the YouTube's processing of the video. Thank you for bringing it to our attention as we can now discuss the matter directly with YouTube. We will pay special attention to the audio in the coming episodes and do all that we can to deliver you high quality experiences while we work to find a resolution to the problem. Hey Space Timers! There seems to be an audio issue for some of our audience members. There may have been a processing error as it's not occurring for all of our audience nor does it seem to be in the original uploaded file. We're going to keep investigating and see what we can do to fix this. In the meantime, we hope you enjoy the content of the episode despite any technical issues you may be experiencing. Thank you for your support!
  • I do not think intrinsic charm quarks can exist but It is possible that even at a low energy collision, when the proton is destroyed the energy which was keeping the proton together might have been released might have made a charm quark.
  • @jgamb914
    Love this channel. I'm not up to speed on all the physics but love learning new things. I usually walk away with new knowledge and a better understanding of the subject matter. Thanks Matt. Great job as always..
  • @mactorresmo
    I´m a theoretical particle physicist and I really appreciate the precise way (and not boring at all) you bring the subject! It is rear to see a Physics Professor that brings information in such accessible way!!
  • @DeltaVTX
    I am made of hopes and dreams. This is not an Undertale reference
  • @gs4945
    I always love how you make some of these tough topics easier to understand.
  • @universemaps
    Another amazing video! The explanation is so clear and concise, and the visuals are stunning. Keep up the fantastic work!
  • @pbsspacetime
    Big thanks to the early gang! Because as noted a few episodes ago: Since our comment response livestream, we've noticed that YT isn't sharing our videos as much with our subscribers. So we're asking our subscribers to 1. switch their subscriptions from "PERSONAL" to "ALL" (just click on the subscribe button and you'll see it) and 2. Watch new episodes as soon as they can!
  • @parkpatt
    This helped me understand particle collision experiments better than I ever have before. Well done! Very clear and engaging presentation
  • @brightwave28
    Used to watch PBS space time 5-6 years back.. good to see you guys are still going strong. Keep it up!
  • @Ahop63
    Incredible job of making this complicated topic very approachable and understandable by those of us that are not particle physicists.
  • @Ignirium
    I've also noticed my intrinsic charm vanishes almost as instantly as it arises, whenever i speak.
  • Great episode! Congrats to the whole team :) It all came together in a beautiful synergy. You are doing amazing work popularizing very difficult and cutting edge science! Gives one a whole new appreciation about the world, and the physics behind it :)
  • @MrOvergryph
    Wow, I actually understood Matt O'Dowd on 2x speed without rewinding, finally. That's a first. :) It may never happen again, but it happened once! :D I usually have to rewatch his videos several times at a slower speed to really digest the material because it's all so new to me and so very complicated.
